      This Sleeplanner twelve inch king size bed with I-gel infused memory foam is an absolutely incredible bed for the price. It arrived vacuum sealed in a box roughly three and a half feet tall by about two feet wide. I was easily able to carry it upstairs, unpack, and set it up by myself. I gave it the full 48 hours to decompress, but you could tell it had literally JUST been sealed up and shipped out, because it decompressed to the full twelve inches within a few hours. It is extremely plush to the touch, and we have had incredible nights of sleep every night we've owned it. Memory foam has always tended to make me sweat really badly overnight, but this bed, with the I-gel, has eliminated that problem. Somehow it naturally adjust to a very comfortable temperature all night. I guess it is just the right amount of absorption and airflow. As always, Overstock has deliver what was promised and my wife and I are very happy sleepers.

      Completely worth EVERY PENNY!!! Husband and I have been shopping for a new mattress for about 6 months. I knew I wanted a gel memory foam but I couldn't decide on one. My previous mattress was a sleep number and while it was amazing, I wanted a gel memory foam. I have also had 2 spine surgeries so comfort and support was an absolute MUST! After many months of comparing Puffys to Purples, Simmons to Serta and everything in between we had finally come across the perfect mattress. It was the Simmons Beautyrest Black Scarlett plush. Of course! A $6,000 mattress. While I could have swiped my card at the Mattress Store and had it delivered the next day, I decided to look on Overstock and see if they had anything close to comparable. After going through other reviews on multiple other mattresses, I came across this mattress. The specs were on target for what we liked and the reviews were great, not to mention, it was under $400 vs $6,000!!! So, without hesitation, I bought it. A week went by while we patiently waited for our new mattress to arrive to see if we bought a dud or not. It arrived exactly 1 week later, right to my doorstep. Hubby got it in and unfurled it. It immediately proofed up but we waited another 24+ hours before actually laying down on it to try it out. There was a slight smell that was expected but it went away in a few hours and wasn't really even noticeable unless you put your nose right next to the mattress. After the 24 hour timeframe passed to let it fully poof up, we tried it out..... Oh...my...goodness! Perfection! It was JUST like laying on the $6,000 mattress!!! We also ordered some 1800 thread count sheets for it and it was like sleeping on a cloud!!! Hubby and I are always in the bed when we are home now. Waking up in the morning is good and bad thing. Good because I actually wake up rested from a good nights sleep. Bad because we don't want to get put of it because we are sooo comfortable! I highly recommend this mattress!!!

      The Queen Memory Foam mattress was delivered on time. The foam mattress came in a box about 4 feet in height and 2 feet wide. I was a bit puzzled if the box was miss labled. When i removed the instruction from the box, placed the rolled up compressed foam mattress on the platform bed and carefully cut away the protective layer and plastic it inflated into a queen size standard mattress. Wow, is all I can say. I was able to use my previous sheet sets and incur any additional expenses.

      I was a little worried about buying a mattress online without ever trying it. When I bought it, there weren’t any reviews but it seemed to have all the features I was looking for. The bed stays pretty cool even though it’s memory foam. The gel layer really helps. It’s very supportive for me as a side sleeper. The right combination of firmness and softness. It sinks a little as you would expect for a non-spring mattress but I don’t have any problems sitting on the edge to get dressed in the morning.

      I had to return this but Overstock customer service took total care of me. The mattress did not expand to 12 inches, only 9 inches in some spots and 10 inches in other and the california king is made like a regular king. The mattress hung off the end of my bed and the width was to short. Would have been a nightmare but after uploading pictures, overstock helped resolve.

      The mattress was relatively easy to maneuver into place and install on my bed. I did it myself but an extra hand would be nice, as it weighs quite a bit and is awkward to handle. I've only slept on this mattress 1 night and can say it is firmer than my previous mattress. When putting my body weight onto my hands while crawling into the bed, the mattress depresses about 3 inches. I prefer a bit more give than this mattress provides (maybe 4-5 inches of give), but I'm still satisfied with it so far. Recommended for someone who prefers a medium firm mattress.

      one side is slimmer than the other side measures ~ 9 inches; all corners are ~ 8 inches high; I waited 10 days for this mattress to expand; maybe I have bad luck on this item; thanks.

      This mattress is so plush I thought I would sink in and never get out! But then it feels supportive, not too soft, and of course I can get out of it easily. So far extremely comfy and it expanded quickly with no smells at all. Memory foam mattresses have come a long way from their early years when they needed several days to expand and air out from strong smells. My only minus is that I think for my use the 12" is too high, now the bed is a little higher than I would like and the mattress pad doesn't fit well. At the time this looked like the best mattress for the best price and I am happy with it.

      If you like to feel hot when you sleep then this is the mattress for you! if you like to sink so deeply into your mattress that it is hard to turn over then this is also the mattress for you! I was eager to replace my old mattress with this new Gel-Infused memory foam one that I found on sale. I ordered it just in time for our upcoming move and since not all of our furniture had arrived both my daughter and I slept on it the first night. My daughter got so hot that she left to go sleep on the couch and I kept waking up sweating and sticking to the mattress. I actually dreamed that I was at a hot yoga class and was stuck in one position because turning over is hard when you have sunken so deeply into the mattress. Since this is not returnable, I have ordered a cooling gel top mattress cover/ topper (another $150) to go on top in hopes that I can salvage this mattress and not have to order a new one. My bargain sale dream mattress has been a nightmare thus far.

      I'm an "edge sleeper". This mattress will dump you into the floor if you are too close to the edge. Anywhere else on the bed and you feel like you are stuck in quicksand. No supporrnon this mattress whatsoever. I truly regret buying this.

      I bought this knowing I haven't bought a new mattress in way too long, and suffer from severe back and hip pain. After buying, the pain I suffer at night is dramatically reduced, but what is most interesting is I've had an MRI since I started sleeping on it and I have a badly torn labrum in my right hip and several bulging discs in my lower back. I am obviously still in pain until surgery, but this mattress has taken the stress off of those areas and has allowed me to sleep in a manner that I have not in months. I definitely recommend this mattress to anyone, but especially if you do not sleep well due to joint or back pain.
