Review: Auvon...😁 - This is extremely comfortable. I like memory foam. I use it on my wheelchair.
Review: Well made and works well - Does improve seat comfort. Cushion is strong enough not to collapse around you, and soft enough to cushion.

## Features

- Secure and Safe. To improve the safety of users in the wheelchair for daily activities, we designed a non-slip bottom and added a detachable strap to help fasten the wheelchair cushion in the wheelchair or other chairs.
- Superior Memory Foam. As prolonged sitting increases tailbone pressure, this chair cushion uses superior memory foam, which better responds to your body heat, evenly distributes weight and relieves your tailbone pain and spinal pain.
- Waterproof & Breathable. The cover was strategically designed with a layer of waterproof membrane, which protects the memory foam from sweat or urine and can be removed for machine washing (do not wash the memory foam). The butt cushion also features vent holes that allow for ample airflow and never trapped body heat.
- Ergonomic Design. The unique U-cutout design floats your tailbone and hence alleviates pressure and minimizes coccyx pain. The slope and contoured surface shapes your lower body while providing support for your thigh with optimal comfort
- Built for Daily Seat. AUVON memory foam cushion (18" x 16" x 3") fits most wheelchairs around 17" - 18" long and 16" - 17" wide, and it can turn seats of scooters, office chairs, car seats, and dining chairs into comfortable seats. Please note, the actual size may vary due to the heat-sensitive nature of memory foam.

## Questions & Answers

**Q: What is the width of the cushion?  The description shows 18" x 16" x 3", further described as 18" deep and 16" wide.  True size?**

**Q: is a replacement cover available for this cushion?**
A: No don't buy falls apart in washer

**Q: Will this work in a Broka high back wheelchair?**
A: As long as your seat is a standard type seat that you sit on I don't see why you couldn't use this one. I use this on my battery operated wheelchair and my manual wheelchair it seems to fit on everything. My manual wheelchair is only a 16 inch seat and it fits perfectly I hope that helps good luck

**Q: Can this be completely submerged under water?**
A: Would not recomend.  Foam inside would not absorb water, and would float.
