Great for body pains.
The mattress arrived in the afternoon in completely vacuum sealed packaging. We opened the seal and were sleeping on the mattress that same night. The firmness is perfect for my wife with chronic pain. It wasn't long before we knew we found a great mattress. We appreciate the ease of process and will be recommending this particular mattress in the future!

Comfortable, Supportive, Cozy, and Refreshing
Never realized the difference a great mattress can make. Sleeping much better now and wake up refreshed and ready for the day! The bed feels thoughtfully designed because it is strong and supportive yet comfy and cozy! I also really liked that the bed shipped in a box that was much easier to move around the house than a full mattress and just opened it up in the bedroom! Love it and will always choose Beauty Sleep!

Great Product!
I recently got this mattress and it has exceeded my expectations. The quality is great! I am a bigger guy and provides plenty of support and I don't feel like I'm dipping all the way through the mattress. It's very comfortable on my back and hips. I don't sleep hot like I used to. Honestly, I am very impressed and would definitely recommend this mattress.
