Ergo系列全背靠墊

I've been using this cushion for my home office chair and the full back coverage makes such a difference compared to my old lumbar roll. The foam stays firm enough that I don't sink into it, even after a few hours of work.

The memory foam genuinely molds to my lower back after a few minutes, and the full-size coverage means I’m not constantly shifting to find support. It’s made my long sitting sessions noticeably more comfortable without that stiff feeling I usually get.

Sat at my desk for a four-hour design sprint without shifting once—the memory foam really does mold to your spine, and it held its shape the whole time. Woke up this morning without the usual stiffness, which is the real win for me.
