### ⭐⭐⭐⭐⭐ Amazing mattress!

### ⭐⭐⭐⭐⭐ Good product

A very comfy style of mattress

### ⭐⭐⭐⭐⭐ Super comfortable
*by A***N on August 13, 2025*

Got this about 6 months ago. It is soft but also supportive. I was hesitant about a bed in a box, but honestly I spent a lot on my mattress from a mate store and I’m pretty underwhelmed considering the price we paid. This mattress was a great price. In fact my sister has slept on this bed twice now and is usually up several times a night and both times she slept through the whole night. She has since purchased her own.
