Good substitutes for yoga blocks include a stack of sturdy books, a firm couch cushion, a folded yoga blanket, a bolster, a sturdy chair, a rolled towel and a stable step stool. Choose something rigid enough to hold your weight without sliding, and set it at a height that keeps your spine long. If you are unsure whether a makeshift prop is safe for a given pose, ask a qualified yoga teacher or physical therapist before relying on it.
Why Substitutes for Yoga Blocks Work at All
A yoga block exists for one reason: to bring the floor closer to your hands, hips or shins. When your body cannot reach the ground comfortably, a block gives you a stable surface at a predictable height. That is the job any substitute needs to do. The material matters far less than the height, the firmness and the stability underneath it.

Most students use blocks in standing poses such as Triangle (Trikonasana), in seated poses such as Easy Pose (Sukhasana) with the hips raised, and in restorative positions where a block supports the sacrum or head. Each use asks slightly different things of the prop. A hand block in Triangle must not tip when you lean on it. A sitting block under the hips needs enough height to tilt the pelvis forward. For a fuller breakdown of what blocks do and why teachers recommend them, see Yoga Blocks Explained.
The Factors That Decide Whether a Substitute Is Safe
Three factors determine whether a household object will serve well. Firmness is first. A soft cushion compresses under load, which shifts your alignment mid-pose and can strain a wrist or lower back. Stability is second. Anything with a curved base, a slick surface or a narrow footprint will roll or slide. Height is third. Standard yoga blocks come in a few common sizes, and manufacturers generally specify heights in inches. A substitute should land close to the height your pose requires, with a little room to adjust.
Material also affects grip. Foam and cork blocks offer friction against the floor and your skin. Wood is firm but can be slippery on hardwood. For a comparison of how these materials differ, read Yoga Block Materials Compared.
Seven Substitutes and How to Use Each One
- Hardcover books. A stack of hardcovers is one of the most common stand-ins. Stack them with the spines aligned and press them together. Check that the stack does not shift when you put weight on it. Use it for hand support in standing poses.
- A firm couch cushion. Choose a cushion that holds its shape under your weight. Sit on the edge, not the middle, so you do not sink. This works well under the hips in seated poses.
- A folded yoga blanket. A dense, tightly folded blanket gives a soft but firm lift. Fold it into a rectangle roughly the width of your hand. Our guide to Yoga Blankets explains which fabrics fold most firmly.
- A bolster. A bolster is a long, firm cylinder that suits restorative poses. It is more useful under the knees or torso than in active standing postures. See Yoga Bolsters for when it fits best.
- A sturdy chair. A chair with a solid seat and four flat feet can support a hand in Triangle or a forearm in Seated Forward Fold. Place it against a wall so it cannot slide backward.
- A rolled towel. A tightly rolled bath towel makes a low, thin support. It suits small height adjustments, such as raising the hips a half inch. Roll it as tightly as possible; a loose roll compresses.
- A stable step stool. Some step stools have a wide, nonslip top and flat legs. Test it with a gentle push before you lean any weight on it.
Practical Steps Before You Substitute
- Measure the height your pose needs. Sit or stand in the position and note how far the support must rise.
- Test firmness. Press the object with your palm. If it dips or squeezes, it will not hold your weight.
- Test stability. Place it on the floor you practice on, then rock it gently. Hardwood and tile need more friction than carpet.
- Keep a second support nearby so you can switch if the first one shifts.
- Stop at the first sign of tipping, sliding or pain. Reset the prop before continuing.
When a Substitute Is Not Enough
Some situations call for a true prop. If you have a recent injury, a joint condition, osteoporosis or a balance problem, a makeshift support may not be stable enough. Adjustable height matters too. A stack of books cannot be fine-tuned by half an inch, which some students need for comfort. In those cases, consult a physical therapist or a doctor before modifying your practice.
What We’d Use
If you want a dependable prop that matches a standard yoga block’s behavior, a foam block with a grippy surface is the most practical upgrade. Look for a product type described as a high-density foam yoga block. View on Amazon
For a firm, flat surface that holds its height under load, a cork yoga block is a steady option. View on Amazon
Related Questions
Can I use a pillow instead of a yoga block?
Usually not for standing poses. Pillows compress, which changes your alignment. A pillow can work under the hips in a seated pose if it is very firm and you keep it stable.
Is a stack of books safe for yoga?
It can be, if the books are hardcovers, aligned squarely and do not shift when weighted. Test before each use and avoid stacks that lean.
How high should a substitute be?
Match it to the pose. Hand supports in standing poses are often set lower than hip supports in seated ones. Adjust in small increments, and see Yoga Pose Modifications for guidance on using props in different positions.
Do I need blocks as a beginner?
Many beginners benefit from them. If you are just starting, Yoga Mats for Beginners covers the basic gear that pairs well with blocks.
Can a strap replace a block?
A strap extends reach rather than raising the floor, so it solves a different problem. For how the two differ, see Yoga Straps Explained.
