Customer Reviews

“The bed didn’t disappoint! Delivery was quick, set up was easy, and that night was the best night of sleep I’d had in months. I’m a 5’8”, 130lbs female with a bad back. I sink just enough to feel like I’m on a cloud (in no way does it feel like I’ve sunk into my bed), yet it’s supportive enough to ease my long-term back pain. 5 stars across the board. I love this mattress.” – Lindsey

“First memory foam mattress that we have owned and after reviewing all the major brands I must say we are very happy with our Signature purchase. The final selling points were the 12″ depth, the superb construction, the pillow top and the life time warranty. I don’t think you can go wrong with a Nest Bedding Alexander Signature Series mattress. The only reason I give it four stars is I have not tried other brands, so I have nothing to compare it to!” – Charles

This is the BEST mattress I have ever slept on. It is firm enough to support my bad back, yet soft enough to take all the pressure of my body. Also the mattress is a fast responding foam so you don’t get the stuck feeling known with memory foam. I am 6’1″ 180lbs and sleep on my side 90 percent of the time and a little on my back and I am very comfortable in both positions. Shipping was fast and ordering was easy.” – Westair
