Excellent mattresses, we initially bought one to try and it was absolutely fantastic. Came in a box and as soon as we opened it, it expanded into a full size mattress. They recommended 24 hours but in two hours it was already expanded. We ended up buying 4 more for all of us. 1 king, 2 queen and 2 double. I would highly recommend libertymattresses based on my own personal experience. The quality of the mattresses are really good. I normally have back pain on my old mattress and can't get up in the mornings. However, with this new mattress I'm up like a champ with a good night's rest. Shipping took a day longer than expected but during these times thats not bad at all. Great product, great quality and just amazing to sleep on.
