I upgraded my 10 year old spring mattress to this one. The difference was significant and this mattress felt some much softer and more comfortable. It also doesn’t make sound even when I jump on it. The gel combo is nice. My body sinks a little bit in it but it’s evenly supported. I got the 12” queen size and the thickness helps. My old one was 8”.The mattress came rolled up compressed in a box. It did take a few days to fully expand to max size. It just gets more plumped after each day. The mattress did not have any smell. It was one of the concern I had since I have a bad experience before. This one seems fine so I sleep on it the very first day.I checked the seams for loose threads but didn’t find any. It seems to be well made. The layered combo with gel felt so much nicer than my spring mattress. My body would sink a little and it molds to the shape. But it’s evenly supported and felt comfortable. Overall a really nice comfy mattress. Wish I had upgraded sooner.Unboxing was an entertaining event.Being delivered shortly before my lunch break, I decided to eat lunch at home to give the mattress a head start.After discovering it wasn't at the leasing office, I found it at the bottom of my stairwell. Laugh-crying the entire time, I flipped it up the stairs and removed the box.Assuming I was carefully following directions and advice from prior reviewers, I found myself dead wrong:Upon removing the outer layer of plastic the bed started hissing at me. I quickly realized that meant this thing is about to become very large, very fast, and I needed to act promptly. Thankfully, lifting the half-inflated mattress to the frame was more awkward than challenging.After removing the remaining plastic, it quickly rose to about 10 inches and looked irresistible from the start. I found no obvious defects or dirty material and I recieved the size I ordered.We decided to wait the full 72 hours to give our investment the best chance to floof up.After 76 hours of impatiently waiting we finally laid on it and knew we bought the right bed for us. This mattress didn't slope downward towards my partner, taking me with it, and I found a comfortable position almost immediately. We weigh a combined 315 pounds and are both primarily side sleepers.After 80 hours of this beauty set free from it's vacuum existence, we had our 2" cooling gel topper (became attached to it trying to "fix" our old serta), mattress protector, sheets, pillows and duvet on it at the best time of day. Bed time.Climbing into bed was like being embraced by a cloud without the humidity. I fell asleep faster, after the excitement wore off, than I ever did on the old mattress.3 nights sleeping on this luxury mattress and backaches have slightly decreased, I feel more energized, and seem to be calmer throughout my hectic work day than normal.I can tell this bed was engineered and manufactured with great care and attention to detail. The seams are sturdy and the fabric is high quality. I truly appreciate the design of this mattress. I can sleep peacefully knowing my hips aren't in danger of being jabbed with metal if I shift my position. I can figure out how clothes work in a dignified manner during my state of half-wakefulness 5 early mornings a week.The only negative thing I have to say about this mattress is the hard plastic under the BedStory tag. A problem easily remedied with any mattress topper. Perhaps the company could consider another material to use in the future.This mattress was the right purchase for myself and my husband. It exceeded most of our expectations, while happily meeting the rest. We tend to prefer a softer mattress and have searched for one with proper support for ages. We decided on the Bedstory Hybrid, although it is labeled as a medium-firm, and are not disappointed. I think it will last longer being more firm than others we've tried.BedStory has found themselves a lifetime customer if this mattress holds up.I will update this review after awhile.Edit:9 April 2020This mattress is such a blessing right now.It's still as comfortable and soft as it was the moment I tested it 39 days ago. We have noticed a slight give when we lay close together, as expected, but the support is terrific!Considering the added stress of the current pandemic, I still wake up feeling rejuvenated. It's easier to get out of bed than it was a month ago.I hope everyone is doing well!Edit:29 October 2020I still look forward to jumping in bed every night (mattress review aside, sleeping is a sport in this house) and hanging out in bed playing on my phone in the mornings on my days off.I rotated the mattress 180° about a week ago as it was overdue and my memory foam mattress topper developed impressions where DH and I laid. The hard tag is now by our heads and not once have we noticed its presence (I still recommend a topper to conceal it). There hasn't been any increased sloping since my April update as far as we can tell.I'm removing a star because not everyone wants a mattress topper (they can be incredibly hot), nor can everyone looking to purchase this mattress afford one. The mattress topper is vital to ignoring the hard tag. This is a design flaw that can easily be fixed BedStory!!Overall we're still very satisfied with this purchase and will likely choose this mattress again in the future.I slept well, it was to thick for me I gave it to my granddaughter and her husband. They say it is great value mattress.Ordered for college dorm bed, good buyI'm a few months shy of turning 50 & I can honestly say that I personally have NEVER in ALL my life had such a comfortable mattress! We lost our home & almost EVERYTHING in our home due to black toxic mold. We left it all behind and started over from scratch. We slept on air mattress for almost 2 years & then the Lord God made a way for us to purchase 3 of these brand new Double XL Hybrid Mattresses and 3 platform frames. All I can do is thank the Lord God Almighty for leading me to this very mattress & giving us the funds to purchase 3⁷⁷! I have had Chronic Lyme, a severe black toxic mold infection, and widespread, unbearable chronic pain like you would NOT believe. I spend a majority of my time & life in bed. So when I am saying this is the MOST comfortable mattress that I have ever owned and ever slept on and lived in... I MEAN IT! I had a lot of fairly new bedding (bought a uear & a half before my mattress) so I use on this mattress. There is a thin queen size sponge type mattress topper and a padded water proof mattress cover so I do havea little extra added softness but, not a lot and good quality sheets and blankets. I have traveled as of recently and let me tell you I really missed mmybed and I have NEVER said that about any othermattress/bed I have ever owned. I don't have pain from this mattress eithwr which is amazing. I can not say enough good things about it. It's most definitely worth the $$$! I hope this will help!
