To find the best non-toxic yoga blocks in 2025, I researched, bought, and tested 13 bamboo and cork options. In many cases, the most durable yoga blocks for daily use are made from EVA foam or PVC. Two highly toxic materials that can contain plasticizers, flame retardants, and other additives that off-gas over time, especially when heated or compressed. Since yoga blocks sit close to your face and hands (and get sweaty), I prefer natural materials that don’t release chemical odors or microplastics during practice.
Initially, my goal was to create an arsenal of sustainable yoga equipment for my Vinyasa practice. But over time, I’ve come to rely on these eco-friendly yoga blocks and mats in all of my fitness routines, including my aerial and calisthenics workouts and classes.
I reached out to brands directly to verify the materials and certifications of all blocks. I also evaluated features like stability, grip, comfort, and durability through my weekly yoga sessions. After putting these blocks to the test in real-life practice, I’m excited to share the ones I trust most. Whether you’re flowing through Sun Salutations, building strength, or stretching deeply in aerial silks, there is a set of wood, bamboo, or cork yoga blocks on the list for you.
I’ve also tested a wide range of non-toxic fitness gear, including the best non-toxic dumbbells and clean shaker bottles for protein.

Best Non-Toxic Yoga Blocks, at a Glance
- Overall best non-toxic yoga blocks: Manduka
- Most eco-friendly yoga blocks: Root
- Most versatile: Infinity Strap
- Best bamboo yoga blocks: Hugger Mugger
When I first stepped onto the yoga mat a few years ago, it was all about improving my mobility and flexibility for my aerial classes. Little did I know that yoga would become such an integral part of my weekly routine, right alongside my calisthenics.
Over the past few years, I’ve explored dozens of eco-friendly yoga accessories to find what truly supports my practice. One thing I quickly realized was that, just like with yoga mats, many yoga blocks on the market are loaded with toxic materials. Especially foam blocks. These can release harmful chemicals like PVC and BPA, which are best avoided for a non-toxic practice.
That’s why the blocks I’m sharing with you today are the ones I use and trust in my own practice. EVA foam options are simply NOT safe. The healthiest alternatives are cork yoga blocks, bamboo yoga blocks, and natural wood blocks. I’ve tested each non-toxic yoga block repeatedly and can confidently vouch for its durability, stability, and overall performance, all while ensuring they meet my standards for safety and eco-friendliness.
But first, let’s get into why it’s so important to have environmentally friendly yoga gear that’s 100% toxic-free.
Why Are Foam Yoga Blocks Not Safe Or Healthy?
For more folks, the best yoga blocks are synonymous with Ethylene Vinyl Acetate or EVA foam. However, even though marketed as a “safe” material for sustainable yoga blocks, this isn’t the case. One of the main concerns isformamide, a chemical used to make EVA foam soft and flexible. Formamide is classified as apotential carcinogen and has been linked to developmental issues at high exposures. Studies have shown that EVA foam products can release formamide into the air, posing inhalation risks, especially in enclosed spaces.
and even vulnerable use. You’ll find it in baby floor mats, sleeping bags, and a lot of fitness and sports gear, mainly because it’s cheap, lightweight, and easy to mold.
“Formamide-free EVA” isn’t safe either
Some brands advertise “formamide-free EVA,” which reduces one risk, but doesn’t address:
- Other plasticizers
- Residual solvents
- VOC mixtures
- End-of-life breakdown
Last but not least, as EVA foam ages, it can break down into microplastic particles, especially at cut edges or areas of repeated pressure. While research on direct health effects from yoga block exposure is limited, microplastics are now widely detected in indoor air and household dust.
Beyond formamide, EVA foam can emit volatile organic compounds (VOCs) during and after production. As we previously mentioned in our non-toxic living guide, these compounds can cause respiratory irritation and allergic reactions. Although VOC levels tend to decrease over time, initial exposure can be concerning, particularly for individuals with sensitivities.
Granted, some manufacturers have taken steps to reduce or eliminate harmful substances like formamide from their products. However, the lack of stringent regulations means that it’s often up to the consumer to do their homework to find truly non-toxic yoga blocks.
What is the Best Material for Yoga Blocks?
Cork Yoga Blocks
If you’re looking for eco-friendly yoga blocks that support both your poses and the planet, cork is the way to go. Cork comes from the bark of cork oak trees, which regenerate after harvesting. No trees are cut down in the process, making it one of the most sustainable materials out there. Compared to synthetic foams, which involve chemical-heavy manufacturing, cork is already a clear winner. Plus, it’s impressively durable. My cock blocks have already handled years of use without losing their shape or crumbling under pressure.
One of the cork’s best features is its natural grip. Ever tried to hold a foam block during a sweaty hot yoga session? It’s a slippery mess. Cork, on the other hand, gets even grippier as moisture increases, helping you stay stable in poses like Half Moon or Extended Triangle. Bonus: Cork is also naturally antimicrobial, meaning it resists bacteria and odors—no funky gym bag smell here.
Bamboo Yoga Blocks
Non-toxic yoga blocks made of bamboo are strong, stylish, and a fantastic alternative to synthetic materials. Bamboo is one of the most sustainable materials on the planet. It grows ridiculously fast and doesn’t require pesticides or fertilizers. Functionally, bamboo blocks are lightweight yet incredibly sturdy. They’re firmer than foam but slightly softer than cork, making them a solid choice for anyone who likes strong support without too much give. However, bamboo’s smooth surface isn’t as grippy as cork, so if you tend to sweat a lot during practice, you might want to pair it with a towel or yoga strap for extra grip.
Natural Wood Yoga Blocks
Wooden yoga blocks might not be the first thing that comes to mind when you think of eco-friendly yoga accessories, but they’re a solid option. While they may not be for everyone, their benefits make them a fantastic choice for certain yogis.
First off, wood is 100% natural and free from synthetic chemicals, making it one of the cleanest materials you can use. Unlike foam or even some cork blocks, wooden yoga blocks don’t off-gas VOCs (volatile organic compounds) or contain adhesives that could leach toxins over time. If you’re serious about a non-toxic practice, this is as pure as it gets. Another major perk? Durability. Wood blocks are virtually indestructible. They won’t lose their shape, dent, or crumble over time. If you invest in a high-quality wooden block, it can literally last a lifetime. Plus, they often look stunning, with a natural grain that adds a touch of elegance to any yoga space.
Of course, there are some trade-offs. Wood is hard—really hard. If you prefer a softer, more forgiving surface (or like using a block under your lower back in restorative poses), this might not be your best option. But if you need maximum stability, wooden blocks offer unmatched firmness. They’re excellent for standing poses, arm balances, and deep stretches where you don’t want any give.
The Different Types of Non-Toxic Yoga Blocks
A standard yoga block is what you’ll find in most studios. It’s thicker, more stable, and offers more surface area for support. On the other hand, lean blocks are narrower and lighter, making them ideal for people with smaller hands or for specific poses that require less bulk.
| Feature | Standard Yoga Block | Lean Yoga Block |
|---|---|---|
| Size | Typically 4″ x 6″ x 9″ | Usually 3″ x 6″ x 9″ |
| Best for | General support, sitting poses, balance, deep stretches | Wrist support, subtle lifts, smaller hands |
| Weight | Heavier, depending on material | Lighter and easier to carry |
| Stability | More stable for standing poses | Less stable but great for small adjustments |
| Versatility | Works for most yoga styles | Best for fine-tuning alignment and light support |
When to Use Each Type
Choose Standard Blocks If…
- You’re a beginner and need extra support in balancing poses.
- You do a lot of restorative yoga and need a larger surface for comfort.
- You want a block that works well for most yoga styles.
Choose Lean Blocks If…
- You have smaller hands and struggle to grip a thick block.
- You want a lighter block for travel or easy storage.
- You need subtle height adjustments rather than full support.
Personally, I always go for standard sustainable yoga blocks, despite having small hands. But some yogis even keep both types on hand—standard blocks for grounding and stability and lean blocks for fine-tuning alignment. It all comes down to how you like to flow!
6 Best Eco-Friendly & Non-Toxic Yoga Blocks
1. Manduka Yoga Block
- Safe Materials: Cork
- Weight: 0.6 pounds
- Dimensions: 8.5″L x 4″W x 2.75″Th
I don’t usually rely on the number of ratings when choosing sustainable yoga blocks, but these ones had over 2.000 glowing reviews on Amazon. The Manduka Cork Block is available in 4 sizes to cater to everyone’s needs. It provides excellent support without any give, which makes me feel completely secure in my poses. The grip is great, and the rounded edges add extra comfort for restorative work. I keep reading that it’s “too heavy” to take to class, but honestly, that’s nonsense. It weighs about as much as a full water bottle! I mostly practice at home, but when I do go to class, this block comes with me—no hesitation.
2. Infinity Strap BRIK
- Safe Materials: 100% All-Natural Cork
- Weight: 3.5 Pounds
- Dimensions: 3.5” x 5.5” x 8.75″
The BRIK yoga block has completely transformed my home practice. I used to avoid cork blocks and solely rely on wooden options for a while, but this one’s octagonal design is so versatile that I can’t imagine using anything else now. The different height options make it adaptable for everything from backbends to balance work, and using it against a wall adds a whole new level of support. The grip is excellent—no slipping, even when my hands get sweaty—and the rounded edges make it comfortable to hold during longer poses. These non-toxic yoga blocks are definitely heavier than foam, but that extra weight provides unmatched stability, making me feel more secure in challenging poses.
3. Hugger Mugger Bamboo Yoga Block
- Safe Materials: Bamboo
- Weight: 2.2 Pounds
- Dimensions: 6″L x 10″W x 4″Th
Hugger Mugger yoga blocks seem to have a cult following. And for a good reason. These rectangular bamboo yoga blocks are very durable and offer ample support. The weight gives a solid, grounded feel, yet the hollow core keeps them light enough for easy transport. I love the smooth, rounded edges—they make restorative poses much more comfortable compared to harder-edged blocks. I even tested their strength by standing and lightly jumping on them, and they held up effortlessly!
4. Hugger Mugger Cork Yoga Block
- Safe Materials: Cork
- Weight: 16 ounces
- Dimensions: 3.5 x 5.5 x 9
If bamboo isn’t really your thing, Hugger Mugger also offers eco-friendly yoga blocks made of cork. These blocks have the perfect balance of sturdiness and comfort. Unlike softer blocks that absorb pressure, these transmit my strength efficiently, making me engage my muscles more in every pose. They’re solid and never collapse, yet the contoured edges make them comfortable enough for long-held supine poses. The surface feels smooth and high-quality—nothing about them looks or feels cheap like those foam blocks. At 1.8 lbs each, they’re lighter than I expected, and while carrying a whole stack might be a workout, I’d gladly bring these to class because they’re simply that good.
5. Root Eco-Friendly Yoga Blocks Set
- Safe Materials: Cork
- Weight: 3.5 pounds
- Dimensions: 6″L x 9″W x 3″Th
ROOT offers the best non-toxic yoga blocks for those who prefer to have something more aesthetic. In addition to having a beautiful motif on them, these blocks are sturdy, smooth, and made from 100% solid cork, not just a thin wrap like some other blocks. It’s completely moisture-proof, which was a bit of a surprise. The grip is excellent, and I love knowing they’re sustainably sourced from Portuguese Cork Oak, a tree that naturally regenerates its bark. Plus, supporting a women-owned small business is a huge bonus! Now, keep in mind that ROOT weighs the same as the Infinity Strap BRIK, which is slightly above average.
6. Trideer Cork Yoga Blocks
- Safe Materials: Cork
- Weight: 3.5 pounds
- Dimensions: 6″L x 9″W x 3″Th
Trideer’s eco-friendly yoga accessories were recommended to me by a friend who has been doing yoga for over 7 years. “These are the best non-toxic yoga blocks,” she said. And they didn’t disappoint! The Trideer Cork Yoga Blocks strike the perfect balance between firmness and comfort. Their high-density cork offers incredible stability, making me feel secure even in challenging poses, while the textured surface and contoured edges ensure a comfortable grip. Unlike foam blocks that can compress under pressure, these stay solid and supportive, whether I’m using them for active yoga or restorative poses. They’re also sustainably made! Whether for deepening stretches, seated m
Bonus: Silicone Protective Cover for Yoga Blocks
If you’re still using EVA foam blocks but want to avoid direct contact with them, this food-grade silicone cover is a great option. It fits snugly over standard 9″x6″x4″ blocks, creating a protective layer that’s sweat-resistant, non-toxic, and much more hygienic. The outer textured surface improves grip significantly, while the smooth inner lining prevents friction damage to the block itself.
How To Choose the Best Eco-Friendly Yoga Blocks for Your Needs
Assess Material Safety
When shopping for an eco-friendly yoga block, material matters most. Some materials, like cork, bamboo, and natural wood, are inherently non-toxic. Others, like EVA foam, can contain harmful chemicals. Here’s how to tell if a block is truly safe:
Look for Certifications
- OEKO-TEX® Standard 100 – Ensures that the product is free from harmful substances and safe for skin contact.
- GREENGUARD Certification – Verifies low chemical emissions, reducing indoor air pollution.
- FSC (Forest Stewardship Council) Certified – Guarantees that cork or wood is sustainably and ethically sourced.
- 100% Natural Labeling – Make sure the block specifies “natural” cork, bamboo, or wood with no synthetic coatings.
Considering Density and Weight
A block’s density affects how much support it provides and how it feels during use.
High-Density Blocks (Cork, Bamboo, and Wood)
- Best for: Stability, standing poses, deep stretches, and strong support.
- Pros: Won’t collapse under pressure, excellent durability.
- Cons: Heavier and firmer—less comfortable for restorative poses.
Low-Density Blocks (Foam, Some Cork Variations)
- Best for: Gentle support, restorative yoga, beginners who need a cushion.
- Pros: Lighter, softer, and more forgiving on joints.
- Cons: Less stability—may compress under weight, making balance poses harder.
Tip: If you’re doing a lot of standing poses and active yoga (like Ashtanga or Vinyasa), go for a firmer block like cork or bamboo. If you’re into Yin or Restorative Yoga, a softer sustainable yoga block might be more comfortable for reclining poses.
Size and Shape Preferences
As we mentioned, non-toxic yoga blocks come in different sizes, and choosing the right one can make all the difference.
- If you have average-sized hands and practice a variety of yoga styles, a standard block is your best bet.
- If you travel often or have smaller hands, go for a lean block.
- If you’re taller or need extra support in deep stretches, consider extra-large blocks.
Maintenance and Care Tips for Non-Toxic Yoga Blocks
You wouldn’t roll out a grimy yoga mat for practice, so why let your yoga blocks gather dust, sweat, and bacteria? Proper maintenance not only extends the life of your blocks but also ensures they remain hygienic and safe to use. Different materials require different care, so let’s break it down.
How to Clean Yoga Blocks Based on Material
Cork Yoga Blocks: Cork is naturally antimicrobial, which means it resists bacteria and mold. However, it still absorbs sweat and dirt over time, so regular cleaning is essential. Wipe down with a damp cloth after each use. For deeper cleaning, mix water + white vinegar (50/50 ratio) in a spray bottle and lightly spritz the surface. Use a dry cloth and let air dry. Always make sure to avoid soaking in water, as cork is porous and can weaken if oversaturated.
Bamboo Yoga Blocks: Bamboo is strong and water-resistant, but it’s still wood—so moisture is not its friend. Use a damp cloth with mild soap or a vinegar + water solution to wipe the surface. Dry immediately with a towel to prevent excess moisture from sitting on the block. For stubborn stains, use a gentle bamboo-safe wood cleaner and a soft brush.
Natural Wood Yoga Blocks: Wooden blocks are the most durable but require a bit of care to maintain their smooth finish. Wipe it down with a slightly damp cloth. For deeper cleaning, use a natural wood cleaner or a mix of olive oil + lemon juice to nourish the wood and remove dirt. Keep in mind to always avoid chemical-heavy cleaners, as they can strip the natural finish. Lastly, store it in a dry place, and if the surface starts to feel rough, lightly sand it with fine-grit sandpaper and apply a thin layer of natural wood oil (like linseed or coconut oil).
Foam Yoga Blocks (If You Still Use One): If you have a foam block that you’re phasing out for a healthier option, keep it clean until you replace it. Fill a sink or bucket with warm water + mild soap, and soak the block for 5-10 minutes. Scrub gently with a soft cloth, then rinse with clean water. Then, let it air dry completely before use.
More Eco-Friendly Yoga Accessories To Try
- I don’t always use straps, but when I do, it’s the MeFree Organic Cotton Yoga Straps. They mostly help me deepen stretches since I’m still in the process of achieving my front split.
- My go-to mat will always be this GURUS because it’s entirely made of ethically sourced cork and rubber.
- During my travels, I always use the Manduka eKo mat. This one is made of 100% natural rubber, non-toxic foaming agents, and non-azo dyes. The 1.5mm thickness works great for me since I can’t hold my poses for long with thinner options like 0,5 or 0,8.
- As of late, I am also trying to incorporate the Trideer Yoga Ball Exercise Ball in my fitness routine for stretches and core strengthening. This one has passed Proposition 65-Lead (Pb) & Cadmium (Cd) and California Proposition 65- Phthalates, and it’s made with top-quality non-toxic PVC material.
- If you experience muscle pain, I highly recommend this Yoga Design LAB Cork Roller. I find it to be a very quick and easy way to release tension, massage tissue, and relieve sore muscles once or twice a week.
What Can You Use Instead Of Yoga Blocks?
Of course, you can’t have your non-toxic yoga blocks with you at all times. Especially when you travel a lot. Here are some alternatives to try:
- Stack of Books: This one is ideal for reaching higher positions in poses like forward folds, standing poses, or seated postures.
- Pillows or Cushions: For gentle or restorative practices, extra padding for knees, lower back, or hips, pillows are a great choice. However, I wouldn’t recommend them for fast-paced flows or standing poses requiring firm support.
- Towel Rolls: Need some gentle support in stretching, deepening forward folds, or knee cushioning? You can adjust the thickness by rolling the towel tighter or looser for more or less support.
- Wooden or Foam Balls: These non-toxic yoga block alternatives are fantastic for core work, balance poses, and deep stretches (especially for the back or under the knees). Just don’t use them for large surface support; they are better for targeted areas.
- A Chair: This one is great for standing poses, forward folds, or seated stretches where extra height is needed. Just make sure to opt for a sturdy, stationary chair without wheels for extra support.
- A Yoga Wheel: If you’re working on your backbends, deep stretches, or restorative poses, you can replace your eco-friendly yoga blocks with a wheel.
FAQs About Non-Toxic Yoga Blocks
Can I use a yoga block for meditation?
Yes, a yoga block can be used for meditation to support your sitting posture. Place it under your sit bones to elevate your hips, which can help maintain a neutral spine and alleviate discomfort during longer sessions. It can also be placed under your knees for added comfort and to reduce strain in seated positions. A block can make your meditation practice more comfortable and sustainable, especially for those with tight hips or lower back discomfort. Using a block is a great way to promote proper alignment and focus.
How do I use a yoga block for backbends?
In backbends, a yoga block can provide support and enhance your stretch. Place the block under your upper back to deepen the stretch in your spine, allowing your chest to open further. For poses like a Bridge or Wheel, you can use the block under your sacrum for added support or under your hands in the Wheel pose for extra stability. It’s also helpful for use in a supported backbend, such as Supported Fish Pose, where the block is placed under the back for a gentle stretch. A block can ensure better alignment and safety in deep backbends.
How do I use yoga blocks in poses like Downward Dog or Cobra?
In Downward Dog, you can place a yoga block under your hands to reduce strain on the wrists and help with stability, especially if your heels are lifted or you’re working on improving your form. For Cobra, place the block under your pelvis to gently elevate it, which can prevent compression in the lower back and help you focus more on lifting your chest. Using blocks in these poses adds support and helps you maintain proper alignment while also encouraging a deeper stretch. Blocks can also help you focus on the strength of the core and legs rather than overcompensating with the lower back.
Can I use a yoga block under my feet during standing poses?
Yes, using a yoga block under your feet in standing poses can help with alignment and flexibility. It’s particularly useful in poses like Forward Fold or Triangle Pose, where you can place the block under your hands or feet to increase height and deepen your stretch. The block can also be used to support your foot in poses like Half Moon or Warrior III, providing a stable base. By using a block under your feet, you can improve stability, balance, and overall comfort in standing poses, making them more accessible and effective.
Final Thoughts on Non-Toxic, Eco-Friendly Yoga Blocks
These were the best non-toxic yoga blocks and some additional sustainable yoga equipment I’m using in my practice. In conclusion, many traditional yoga blocks, especially those made from foam, can release harmful chemicals like PVC and BPA, which can negatively impact your health and the environment. Non-toxic and eco-friendly yoga blocks, on the other hand, are made from sustainable materials like cork, bamboo, or natural wood, offering a safer alternative that enhances your practice without compromising your well-being. These blocks provide a more stable, supportive surface, promoting better alignment and comfort during poses. When choosing a block, consider factors like material safety, density, grip, and size to ensure it meets your unique needs, whether you’re practicing Vinyasa, restorative yoga, or integrating them into other fitness routines like aerial or calisthenics.
