Patent CN115445137B
Updated October 30, 2026Universal Folding Yoga Cushion with Waist Support
Seated yoga poses often require external support for the lower back, forcing practitioners to find a wall or carry bulky props. Standard mats offer no structural support. This universal folding cushion solves this by integrating a mechanical folding system directly into the mat. By utilizing pre-scored guide grooves and transverse lines, the user can fold the mat in half, bend the standing section along a vertical curve, and lock the resulting chair-like shape with side buttons. This creates an immediate waist support structure. When unfolded, it returns to a flat, anti-slip yoga mat with textured backing for stability.

The problem
Practitioners performing seated yoga poses often struggle with maintaining proper posture, particularly for the lower back and waist. Without adequate support, users may slouch or strain, reducing the effectiveness of the pose. Traditionally, finding a wall or carrying a dedicated bolster or chair is necessary, which limits where one can practice. Existing folding yoga mats typically focus only on portability and storage, offering no structural support when set up for exercise. They remain flat surfaces, failing to address the need for ergonomic assistance in specific postures.
The solution
The patent describes a yoga mat body integrated with a specialized folding system. It transforms from a flat mat into a three-dimensional support structure through a series of guided bends and locks.
- Fold in Half: The user folds the mat along the first transverse groove, causing half of the mat body to stand upright.
- Bend the Standing Section: Using the second guide groove and the vertical guide groove within the matching area, the standing half is bent backward to form a curved surface.
- Lock the Shape: The inclined guide grooves facilitate the final positioning. Side buttons located near the matching groove are buckled together, securing the mat in a chair-like configuration.
- Provide Support: The resulting curved structure acts as a backrest or waist support for the user sitting on the base portion.

Who it is for
- Home Yoga Practitioners who lack space for multiple props like bolsters or chairs but want support for seated meditation or restorative poses.
- Fitness Studios looking to provide versatile equipment that serves as both a standard mat and a support aid without cluttering the room.
- Travel Yoga Enthusiasts who need a compact, all-in-one solution that adapts to different practice needs in hotel rooms or parks.
- Physical Therapy Centers requiring adjustable support tools for patients practicing core stabilization or flexibility exercises.
How it works
The main parts

| No. | Part | What it does |
|---|---|---|
| 1 | Yoga Mat Body | The primary surface for practice; flexible enough to fold and bend. |
| 2 | Folding Groove | Located on the back surface; aids in creasing the mat for initial folding. |
| 21, 22 | First & Second Guide Grooves | Linear channels that align the mat sections during the folding process. |
| 231, 232 | Transverse Grooves | Horizontal lines perpendicular to guide grooves; act as hinge points for folding in half. |
| 24 | Matching Groove Area | Contains vertical and inclined chutes (241, 242, 243) to guide the bending of the standing section. |
| 11 | Buttons | Fasteners on either side of the matching groove that lock the folded shape. |
| 3 | Support Assembly | Optional internal components (sliding block, plate, spring) to enhance structural rigidity. |
Operating Steps
- Lay Flat: Unfold the mat completely on the ground. The textured back ensures grip.
- Initial Fold: Bend the mat along the first transverse groove (231). One half stands vertically.
- Curve Formation: Apply pressure to the standing half, guiding it along the second guide groove (22) and vertical guide groove (241) to create a convex curve.
- Final Lock: Adjust the angle using the inclined chutes (242, 243) and snap the side buttons (11) together to prevent rebound.
- Use: Sit against the curved backrest for waist support. To revert, unbuckle buttons and unfold.

Applications
Home Meditation and Seated Poses
Users practicing Sukhasana (Easy Pose) or Padmasana (Lotus Pose) at home can use the folded mat to support their lumbar spine. This helps maintain an upright posture without relying on a wall, allowing for longer, more comfortable meditation sessions in any corner of the house.
Restorative Yoga Classes
In studio settings, instructors can utilize these cushions for restorative sequences where students need passive support. The ability to quickly transition from a flat mat to a backrest saves time between poses and reduces the need for storing numerous separate bolsters or blocks.
Travel and Outdoor Practice
For yogis traveling or practicing outdoors, this dual-functionality eliminates the need to pack extra props. A single lightweight mat can provide a stable surface for standing poses and then transform into a supportive seat for cooling-down stretches, ideal for park benches or uneven terrain.
Physical Rehabilitation
Therapists may use the adjustable support angle to assist patients in strengthening core muscles or improving flexibility. The firm yet cushioned backrest allows for controlled leaning, helping individuals regain posture alignment safely during recovery exercises.
Where it is less suitable
- High-Impact Activities: While sturdy for yoga, the folding mechanism may not withstand vigorous jumping or intense cardio exercises compared to solid rubber mats.
- Fixed Angle Needs: If a practitioner requires a perfectly rigid, non-adjustable chair, traditional furniture might be more appropriate than a flexible mat-based structure.
- Very Large Users: The dimensions of the mat limit the size of the support structure; taller or broader individuals might find the waist support insufficient or uncomfortable.
Frequently asked questions
How does the folding mechanism work?
The mat uses a series of pre-scored grooves and guide channels. You fold the mat in half along a transverse line, then bend the standing section along vertical and inclined grooves to form a curve. Finally, side buttons snap together to lock the shape into a chair-like support.
Does it stay flat when unfolded?
Yes. The grooves are designed to allow easy folding but do not compromise the flatness of the mat when fully extended. The material selection is critical here; a suitably elastic compound ensures it lays flat without curling.
Can I wash it?
Cleaning depends on the chosen material. Most TPE and rubber mats can be wiped down with mild soap and water. If the design includes fabric covers or electronic components (though none are mentioned in the basic claims), care instructions would differ. We recommend specifying wipe-clean materials for ease of maintenance.
Is the waist support adjustable?
The patent describes a specific folding path that results in a fixed curved shape once locked. However, variations in the depth of the grooves or the length of the mat could allow for slight adjustments in the curvature. Custom designs can explore variable locking points.
What materials are available?
We can produce this design using natural rubber, TPE (thermoplastic elastomer), or PVC. For US markets, we strongly recommend non-toxic, eco-friendly options like natural rubber or TPE to meet consumer preferences and regulatory standards.
How durable is the folding mechanism?
Durability relies on the quality of the mold and the fatigue resistance of the material. The buttons and grooves are integral parts of the mat body. With properly specified polymers, the folding action can be repeated without breaking. Prototype testing is essential to confirm lifespan.
Can this design be made and sold in the US?
The patent CN115445137B is filed only in China and has no US counterpart. Therefore, this specific patent does not restrict you from making or selling this design in the US. However, you should conduct a freedom-to-operate search to ensure no other US patents cover similar folding yoga mat technologies.
