    • Nuform Luxury Gel Memory Mattress

      I'm very happy with my memory foam mattress. It's firm but not too firm. I was having pain from my other mattress... With this mattress I feel much better. It only took 24 hrs for it to reach its max wasn't quite 11 inches but its close enough for me at 10 1/2 inches. No odors from the memory foam. I would recommend this mattress.

    • Exceeds Expectations!

      I purchased the king 11-inch NuForm gel memory foam mattress. It was my first major online purchase and my first memory foam mattress - so major risk-taking, especially considering that no one had reviewed this mattress! This was the most pleasurable and hassle-free shopping experience I have had. Smooth sailing from start to finish. Mattress arrived earlier than anticipated and was much easier to set up than expected. It is heavy but my daughter and I handled it with no problem. It expanded quickly and I was able to sleep on it the same night it was delivered! It is a bit firmer than expected given that it was labeled "medium" on the description. I am happy with this however as I was a little worried about sinking in too much. Memory foam takes a little adjusting to but I can tell after only a few days that I am sleeping better (less tossing and turning) and awaking with fewer aches and pains than with my old traditional coil mattress. This mattress seems very comparable to more expensive, well-known brand gel memory foam mattresses that I tested in mattress stores. I will not hesitate to buy a mattress through Overstock in the future. This mattress is an exceptional value. I purchased with a platform bedframe that takes the place of buying a traditional box spring and with this 11-inch mattress, my bed is at the perfect height. I am thrilled!
