Ergo系列舒適坐墊

The gel layer genuinely stays cool even after an hour on a hot desk chair, which was my biggest worry before buying. My lower back feels noticeably less stiff by end of day, and the memory foam holds its shape without flattening out.

I’ve had mine for two weeks and the memory foam actually holds its shape instead of flattening out by lunchtime. My lower back feels noticeably less stiff after a full day at my desk, which is something I wasn’t expecting from a cushion.

Spent eight hours in it yesterday and my lower back actually felt fine when I stood up, which never happens with my usual chair. The gel layer keeps it cool even on a hot afternoon, so it doesn't turn into a sweaty mess. That foam-gel combo really does take the pressure off my tailbone.
