Editor's Pick: If your office chair cushion is too thin, your tailbone can easily get numb after sitting for a long time. This thick memory foam cushion supports your entire hips and lower back, and its U-shaped opening leaves space for your tailbone. The non-slip bottom keeps it in place when you stand up and sit back down. Perfect to use when driving or flying.
