  • It needs time to fill out, 12 hours
Size: King Style: 14 Inch Pattern Name: Medium Firm
I wasn't sure this bed would help me sleep any better, but after three nights, It feels great. It took some time to fill out after opening the package, (About 12 hours) but it seems to get more comfortable the more I sleep on it! Good choice for the money

  • Very Supportive and Comfy
Size: Full Style: 10 Inch Pattern Name: Medium Firm
This is a really nice mattress. Not just for the price but overall. It came out of the box easily and was ready for use next night. I bought a plush, and it is more of a medium to plush, soft on top and very deeply supportive. It does not sink in or feel bouncy, but maybe because I don’t use a box spring. I would buy it again. Ver nice. ... show more

Value of the money and quality sleep is guaranteed. I love that it has no smell at all and the size is exactly what I ordered. Will see how long it lasts.

  • Comfy bed…can’t beat the price!
Size: King Style: 14 Inch Pattern Name: Medium Firm
My husband loves this mattress, I don’t love the springs but when you’re sleeping on it you don’t notice it at all, only when you’re making the bed and feel the sides, otherwise, very comfortable! We got the 14” deluxe hybrid
