## 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 makes this cushion different from others?**
A: This cushion is specifically designed for wheelchair comfort, relieves pressure and supports all-day sitting. The U-cutout eases tailbone pain, the contoured slope supports thighs, and breathable anti-bedsores fabric keeps skin dry.

**Q: Has a slight odor or the cushion feels firm?**
A: Due to sealed packaging during shipping, you may notice a slight odor when first opening — it fades within 2–3 days. Cold temps may also make foam feel firm on arrival. Let it rest 48h at room temp, or sit 10–20 min — body heat softens it.

**Q: Is it slippery?**
A: No. This wheelchair seat cushion features a dual anti-slip design with large anti-slip particles on the bottom and an adjustable strap to keep it securely in place on your wheelchair or chair during daily use.

**Q: Can I clean it easily?**
A: Yes. The removable cover includes a waterproof membrane that helps protect the memory foam from sweat or moisture. The cover can be washed separately in cold water on a gentle cycle and air-dried. Do not machine wash the memory foam core.

**Q: Will this cushion fit me?**
A: Yes. It measures 18"×16"×3" and fits most wheelchairs (17"–18"×16"–17"), scooters, office chairs, car seats, and dining chairs. A great choice if you're dealing with tailbone, coccyx, or spinal discomfort.
