LIFEMENT Basic Twin Cooling Gel Infused Memory Foam Mattress in a Box | Medium Firm Bed, Fiberglass Free, Certified Pressure Relief Foam, Cooling Comfort Sleep, 10 Inch

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.

I recently received the Lifement Full Element Memory Foam Mattress and we're really happy with it so far! When the package arrived, the mattress was compressed and tightly packed. Once we opened it, it expanded very quickly and was fully inflated in about 25 minutes. It's very comfortable and a great size for my son. He's 13 years old and about 5'7”, so he's pretty tall for his age, and the mattress fits him perfectly. When he laid down on it, he immediately said how comfortable it felt. I also added a foam mattress protector just to help keep it protected. Overall, I definitely recommend this mattress, whether it's for a growing/tall child or even for yourself!
