Review: Comfortable and great cushion - Comfortable! Great cushion!
Review: A comfortable cushion! - This has been a very satisfying cushion I'm happy I purchased this particular seat cushion Thank you!

## Features

- Soft Velour Fabric
- 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.

**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.

### ⭐⭐⭐⭐⭐ Pressure and Pain Relief
*by I***S on May 27, 2023*

I am sitting on it right now, to write the review. It is the 18"x16"x3" cushion. It really makes a difference on these old hurt hips on my wooden chair at the computer. I am a larger person (not huge but no where near petite) and over 140 pounds-that's why I chose this cushion- meant for >140 pound people. I have tried a number of cushions and the problem was always that a plain square cushion or a couple of pillows never could do what this cushion does- which is twofold- it has a cutout so my tailbone doesn't get sore like it always did after hours on the computer, and second- the front tapers down. I never gave it much thought before, but having the taper means the cushion isn't constantly digging in and applying unneeded pressure on the back of my thighs. Both the cutout and the front edge taper really make quite a difference. The soft fabric on top is nice. The rubber grips (on my chair at least) stop it from moving around so well, that I have not needed to use the removable strap at all. I cannot speak to durability as I haven't had it that long yet, but it seems well made and sturdy. Like anything that is memory foam- it sinks down when weight is on it, but it still gives some cushioning as needed, and when I get up, it (so far) fairly quickly bounces back to it's normal height of close to 3". All in all- I am very happy with it, and intend to get another for the easy chair in the living room-which lost it's 'easy' many years ago.
