  • This is a very good mattress.

    It took a few days to get used to the new mattress, only because I haven't slept on one before. Now it is sleeping on a cloud. The gel in the mattress does keep it cool, I do not get hot at all.

    I bought 2 mattress to replace our 1 king size for 2 reasons. First, it will be easier when we move to handle the two instead of one large one. Second, I was looking for a solution to the "bounce" problem when one person rolls over. Success!

  • Great matterss

    I called the local mattress place and this was half the cost of their mattresses. The quality of this is great, my girl loves it. It arrives vacuum packed, just cut the plastic and it is actual size after it gulps in all the air. No complaints.

  • Awesome great....we ordered three!

    It was time for our three school-aged kids to get new tend to grow so they need the support, right?! After looking and looking at traditional mattresses, I was completely unimpressed..and believe me, I do my research. So my cousin happens to mention that she bought her traditional mattress from Overstock and she loves it. I go looking and again....did not find what I wanted for the kids...until I took a good look at the Spinal Response mattress. I ordered my son's first, figuring I would return it if it did not work out. It took him two nights to give an opinion...and it was "I feel like I am floating on a cloud"! That's all it our two girls had to try out the mattress and they were hooked, too! Next week or so later, I ordered two more for them! I purchased three metal platform bedframes with 14" high legs and this height combined with the height of the mattress does make for a rather tall bed, but the kids love it. All summer long, they've slept quite soundly...and no one woke up too ungodly early. School is starting in it's school-night bedtime....and all three go right to sleep when it's bedtime. Our tip: We cut and unfolded the box in which the mattress is delivered to fit the flat top of the metal platform bedframe. This helps preserve the integrity of the bottom of the mattress from and potential snags on the frame and will stay clean and free from any dust. Plus, it makes it easier to move the mattress on the frame if needed. Hope you enjoy this mattress also!

  • Super comfy mattress

    I'm currently living in a rented college apartment and the bed/mattress sucks. As a more 'mature' student I wasn't prepared to put up with such a crappy mattress. I tried a memory foam topper, which helped a little but I still wasn't getting a good enough sleep. ISo, I bought the Gel Memory Foam Mattress and have been using it for over a week now (on top of a wooden slatted bed frame) and it is truly wonderful ! The gel/aloe makes a difference. It came very well packed into a cardboard box and I had trouble believing that there was a mattress in the box! Once unpacked, I left it overnight to go back to its normal shape. I think it's a bargain for this price and I am really pleased with my purchase.

  • Great buy

    After more than a year, it is still as good as the priciest ones we tried out.

  • Would be great for an average person

    It feels fairly firm when you first lay down, but it will sink after a while and even lose some of the support. Maybe because I weigh 200lbs. I added a 3" memory foam topper and it helped with the sinking feeling. I was not as comfortable as am after waking in my sleep number bed. I think it would be an excellent mattress for a guest room or a slim teenager.

  • ...and that bed was just right... zzzzz

    Pleasantly surprised by the quality of this product, admittedly took about 48 hrs to reach it true dimensions. Was tough to rate on the comfort scale; supportive yet it is still somewhat soft (I'm not a fan of firm mattresses). Perfect for my tastes. The cover is very attractive.

  • I love it!

    I bought this mattress not knowing whether or not I would like the memory foam. My only experience with memory foam was during a sleep study and I liked sleeping on the one at the hospital's sleep testing facility. I found this mattress on and for the price I figured if I didn't like it I could use it for a spare bed in my guest room. The mattress comes in a fairly good sized box but was easy for me to handle as it was tall and skinny. The mattress itself is vacuum sealed in plastic. When I opened the plastic it quickly expanded to its full size. It had an odor (not God awful) to it which I had expected because I had read it would have in other memory foam reviews. I let it sit for a few days and the smell dissipated enough to use it. Now that I've been using it for over a month I can say that I am so glad I purchased this! It is the most comfortable mattress I have ever slept on. It cradles the body while giving it good support. If there is any drawback that I can think of it would be that it gives quite a bit when I'm sitting on the edge of the bed but it is not a big deal. I am now trying to talk my boyfriend into buying a memory foam mattress for his motorhome because I don't know if I will be able to stand not sleeping on one when we go on trips!

I'm looking for 2 TwinXL's to replace the mattresses on an adjustable Cal-King bed. Can this mattress be used on an adjustable bed? sweetland on Sep 14, 2013

Hello sweetland, we appreciate your inquiry. Unfortunately, this item would not fully replace a Cal King mattress, but would replace a King, as there is a few inches difference between the two.
