What Alexander Signature Series customers have to say

  • “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

The finer print


The Alexander Signature Series ships free to the lower 48 states and usually arrives within 3-7 business days.


This mattress comes compressed, rolled and boxed. You will simply open, unroll, remove the plastic wrapping and watch it grow.


The Alexander Signature Series should be used on a non-flexible base. If using slats, you’ll want to make sure they do not bend at all and have good center support. You should not use this mattress on the floor, older style flexible box springs, slats that are flexible or bowed, or slats that are more than 4″ apart.

Return policy

If you decide the Alexander Signature Series mattress is not for you after at least 30 nights and within the 100-night trial period, you can either exchange the mattress for another model/feel or return it all together. You can donate your unwanted bed to a local charity and have your original purchase price refunded in full.


Nest Bedding offers a limited lifetime warranty on all their mattresses.

Bonus points

  • Made in the USA.
  • All foams are CertiPUR-US certified, meaning they’re good for you and the environment.
