## Description

## Features

- Polyester, Cotton
- Imported
- UNIQUE CUT-OUT DESIGN: This firm, high density memory foam cushion reduces pressure on your spine, tailbone, and lumbar discs. It ensures your tailbone doesn't touch the sitting surface, preventing discomfort or soreness.
- RELIEVES PAINFUL PRESSURE POINTS: Provides excellent back support and relieves the side effects resulting from pressing on the lower tailbone area. Getting rid of this pressure helps relieve hip and back pain, pregnancy related pain, herniated discs, sciatica, an injured tailbone, pressure sores, and numbness.
- FIRM, HIGH DENSITY MEMORY FOAM: Heavy Duty Thicker Memory Foam to Support Heavier Users. (Size - 18" x 16" x 3.5"). High density prevents cushion from flattening.
- CURVED SURFACE PROVIDES SUPPORT FOR BUTTOCKS, HIPS, AND THIGHS: Ergonomic design gently cradles your buttocks and the back of your upper thighs with its curved surface, evenly distributing weight and promoting proper posture and spinal alignment. Perfect for Office, Car, Kitchen, or Dining Room Chairs.
- WASHABLE, BREATHABLE VELOUR COVER WITH BUILT-IN HANDLES AND NON-SLIP BOTTOM: The high quality cover made with tiny holes to improve circulation and prevent the buildup of moisture or sweat, making it an ideal choice for prolonged use. Simply unzip the removable cover and place it in the washing machine or hand wash it for a fresh and clean sitting. Non-slip bottom keeps your cushion in place. Built-in handles make it easy to bring it with you wherever you go.
