AirLiner

Took a while to get the air out of the foam after unboxing, but once it settled, the support for my back was noticeably better by morning. The standard thickness feels just right for a medium-firm sleeping surface.

Installed it under my existing mattress and woke up without my usual back stiffness for the first time in months. The standard size fit my queen frame perfectly with no sagging edges.

The fit is noticeably more comfortable than the last cheap liner I tried, and it stays in place even during a long walk. It’s also way easier to clean than I expected, which is a huge plus for daily use.
