Best Price Mattress 11" Essential Gel Medium Memory Foam Mattress, Twin

I was thrilled, to get the Best Price Mattress Gel-Infused Memory Foam Mattress, to review - because I desperately needed a new mattress! I got a queen size mattress and was very eager to see what happened, once I took it out of the box and unwrapped it. I had never seen a boxed mattress, up close, before - just in ads, on the internet. So I was really anxious, to see this mattress unfold, to it's full size. Once the rolled/compressed mattress is removed, from the box, the mattress begins to decompress. Lay it on the bed, zipper side down, right away. Cut away and remove the remaining protective plastic. The mattress will soon decompress to it's full size. (The instructions state the mattress takes 48 hours to decompress fully and wait until then, to add bed linens.) The instructions state there may be an odor, from the mattress being sealed in plastic, however I detected no odor, with mine. My mattress, once unrolled, went from about two inches to approximately 7 inches high, in less than 10 minutes. However, I waited before trying to sleep on it, for the first time. So far, setting this mattress up, has been very simple and I was able to do it, all by myself. After sleeping, on the mattress, I have only good things to say, about it! As someone with chronic back issues, I am accustomed to waking up and being in pain. I had yet to find a mattress, to give me any relief. Even though I have a lovely mattress topper, which cushions me nicely - it did nothing to help alleviate my pain. This wonderful new mattress does just that - as it conforms to my body and relieves the pressure points, which have always caused me such discomfort. This mattress supports me, but is not hard - it cushions my body, while supporting it and allows me to sleep comfortably. I do not find myself shifting around, constantly trying to find a better position, to sleep. Instead of waking up, stiff and sore and TIRED....I woke up, with no pain and felt rested. I am extremely happy, with this mattress and would highly recommend it, to others!
