SitzRight Seat Cushion SOLD OUT ONLINE The SitzRight Seat Cushion relieves pressure on your sitz bones and tailbone by distributing your weight more evenly. Made of soft, supportive EVA material, it was designed to help you sit with better posture, alleviating fatigue and discomfort. Measures 18” x 14” x 4”. Most chairs don’t support a normal lumbar curve. But the SitzRight cushion has a unique ergonomic design that slopes downwards to support a healthy lumbar curve, giving you instant lower back pain relief. The contoured design has higher pillars in the back that prop your pelvis up and open the angle between the upper body and legs, reducing strain on the hip joints and encouraging proper posture. SitzRight also features a unique cutout that provides pressure relief for your tailbone. The seat promotes better airflow to reduce heat and humidity for extra comfort. It’s even waterproof and washable for easy cleaning. Start sitting better with SitzRight.
