インテグリティ スタティッククッション - 低リスク - 17インチ x 17インチ

The weight distribution is noticeably better than my old foam pad—after a full day sitting, my tailbone doesn't ache at all. The 17-inch size fits my chair perfectly.

I’ve been using this cushion in my desk chair for a few weeks now, and the 17x17 size fits perfectly without sliding around. The foam has a nice firmness that keeps my hips aligned during long workdays. Really glad I picked this for low-risk support.

Finally a cushion that actually stays put on my chair. The 17x17 size is perfect for my desk, and I can feel the weight distribution working during long work sessions.
