Review on MeMoreCool Memory Foam Camping Mattress Pad - Portable 3.5" Foldable Floor Mattress For Travel And Guest Bed by Peter Nobles

Left out for a week to puff back up from the vacuum sealing it came it. At the thickest part, 2" tops (see pic). That being said, it is comfortable for only being 2", but side sleepers on hard surfaces will likely bottom out. Using as a supplemental cushion on a firm futon, which works fine, but for a standalone pad I'd look elsewhere.
