Great affordable option
I've been suffering from lower back & hip problems & this has helped with making sleep more comfortable. I opened it in the morning before leaving for work thinking there's no way that's fitting my king size bed but when I got home that evening it had filled out @ fit it perfectly!

Comfortable
I wanted to try it because my back has been killing me with the mattress that I recently brought and this item has helped me sleep well and not make my back hurt at all and it's very comfortable!
