OYT 6" Twin Size Gel Memory Foam Mattress - CertiPUR-US Certified, Pressure Relieving & Supportive, 39"x75"x6" Mattress in a Box | Perfect for Kids Rooms, Guest Beds & Small Spaces

I was skeptical about buying a mattress that comes in a box but I am so glad I did!!! I bought the 14” king size and let it set out for 2 days to rise and it did rise to about 14 inches.It is also about 78” long and not 80” but not a big issue for what we need.I’m very picky about mattresses and this one blew me out of the water with the quality and comfort. My husband and I love this mattress!!! It’s not too soft but not too hard and it cradles your body perfectly. No topper needed. Doesn’t get hot and is supportive enough to sit on the side of the bed comfortably. My husband even mentioned his lower back pain was better. For the price, you really can’t beat it. Buy it, you won’t regret it!!
