BEHOST 8 inch Twin Mattress, Breathable Cooling Memory Foam Mattress in a Box, Fiberglass-Free, Medium Support

I got this mattress after sleeping on a sleep number for over 12 years. I don’t know if it was my body or the bed but I was having more %26 more trouble sleeping, staying asleep %26 being comfortable. Having said that I am a 50 year old RN. I have hard earned body aches and lovely hormone changes contributing to my sleep struggles. I did not have a lot of money to put into a mattress, but having read the reviews and comparing with other mattresses out there, I decided to give this a try. I am more than pleasantly surprised! It is such a comfortable mattress! Soft, yet supportive. It’s firm enough, but in a cushiony way. I’m going on 8 months with mine and I still love it. I just bought another one for my daughter. And she loves hers also. I am a flipper and flopper, I sleep mostly side, some stomach %26 rarely my back. Unlike my previous bed, I can really sleep in any position in the bed and sitting up an reading is also comfortable. I put mine on a metal bed frame with 5.5 inch spaced slats. So far so good. BTW, it comes tightly wrapped in many layers with a letter opener type of tool to cut the plastic. Once the outer plastic is off, I put it on the frame to remove the last layer. It’s a very heavy mattress, but my daughter and I managed to lift it upstairs and onto the frame. Once you cut into the last layer of plastic it expands VERY QUICKLY. It can be used right away as far as I can tell, but it takes days to fully expand.
