LIFEMENT Basic King Cooling Gel Infused Memory Foam Mattress in a Box | Medium Firm Bed, Fiberglass Free, Certified Pressure Relief Foam, Cooling Comfort Sleep, 6 Inch

How in the world did they get this wrapped up so small? I thought I'd been sent the wrong size at first! It unrolled out to a normal queen size though. I like that it unfolds flat and then you open it. My last mattress you had to open it first and we accidentally had it backwards which was a pain to flip around. It started plumping up immediately, though I'm confused on if "Mattress should be unwrapped within 72 hours to fully expand" means it just needs 3 days to expand or you need to open it within 3 days of receipt to avoid causing damage? Very weird choice of words. The fabric is super soft and cool to the touch though, and I'm very happy with how it's looking so far!

Perfect for side sleepers or back sleepers. Takes about 12 hours to fully expand but it is well worth the wait. Just the right amount of support- not so soft you sink, but not so firm that you feel like you're sleeping on a board. Overall, excellent value for the money.
