Customer Reviews on the Alexander Signature Series

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
