xElevate everyday seating with Sigmat
Designed for comfort you can feel, the Sigmat Memory Foam Seat Cushion blends a plush memory foam core with a durable grey cover. Its 13-inch diameter and 1.2-inch profile provide a supportive, low-profile addition to a wide range of chairs, from desk stools to dining seats. The foam cushions the sit bones while adapting to your body shape, helping to minimize pressure points during longer sessions.
The cushion features an anti-slip backing to help it stay in place on most surfaces, so you can focus on your task, conversation, or travel without constant adjustment. The cover is removable for easy care, and the fabric mix (86% polyester, 14% nylon) offers a soft touch that remains comfortable through daily use. Whether you’re at work, at home, or on the road, this cushion adds a subtle layer of support to your seating experience.
