This new twin bed is awesome! It fits perfectly in a twin bed frame and it’s high enough to not need a bed frame. It’s super comfy and very thick! My daughter is really enjoying her new mattress she says that it keeps her cooler overnight then her last mattress. It has green tea infused into it and it it feels super fresh! It came in a tall box compressed in a roll but it expanded in less than 24 hours! It’s an awesome mattress I definitely recommend!
