Vibe 12-Inch Gel Memory Foam Mattress | Bed in a Box, [Mattress Only], Twin XL (410263-1120)

I purchased this mattress (the 12" Cal King) in 2020, and it's now five years old. I've intentionally waited a long period of time after purchasing to leave this review. The main reason for me doing this was because I truly wanted to give an honest appraisal of the mattress that truly reflects its longevity and how it lasts in the long run -- not after a few weeks like some of the reviews you see.So, this mattress? It's good stuff. Honestly. As long as the materials and structures are the same within the mattresses, I can 100% vouch for this product. I'll break it down a little bit:When I ordered this mattress, it came in a box as expected. Same process as everyone else. Put it on the base, unroll it, open it, and let it rise. In a few hours, it expanded to full size. We were able to sleep on it the same night, and it's been great ever since. There were no issues with corners being mashed or dips in the foam. I keep seeing people complain about fiberglass, and while I'm aware that fiberglass is used a fire protectant, I haven't had any issues with it myself. Of course, I also haven't tried to take off the cover, and the mattress went directly into an encasement before we slept on it. There's not really any reason to actually take the cover off anyway. If you're concerned about stains or keeping things clean, spend the $30 and buy an encasement or a cover. If it gets stained or dirty, you can wash it or throw it out and you still protect the mattress. Pretty simple concept.This bed is quite comfortable (and frankly one of the most comfortable mattresses I've ever owned -- including a $3000+ Serta set), but it's important to remember that bedding preferences are going to be different for virtually every person because of our individual preferences. To me, the bed has a very solid base of support that progressively softens until the top. This lends the mattress to providing a firm support underneath a really floaty support layer. If you push down on the bed, you'll find that it's pretty solid. Once you lie on it, however, you'll notice that it cradles you. Only recently have I started having some pain from sleeping, but that's likely due more to me than the mattress (other factors here like multiple pillows, the way I sleep, etc.). So, to reiterate: this mattress is both firm and plush, supportive and cradling. If you don't like this feeling or prefer to have an extra firm mattress with no give, then this one isn't for you. Temperature-wise, it's been comfortable and never hot.As far as stability, this bed has been solid for five years now. It's only recently started to show signs of being worn. Part of this is my fault, of course, because I'm a big guy. Regardless, having a sub-$500 mattress last this long is pretty good, I think. I've had more expensive mattresses that didn't last this long. I'm sure it'll last some folks even longer. Make sure that you've got it on a solid base because it is pretty heavy, and if it's on slats, make sure they aren't more than about 3" apart to help keep the mattress in good shape over the long-term.Ultimately, if nothing has changed with the mattresses, I feel confident in saying that this is a good quality, well-made mattress that's worth the money. The price is gone up by about ~$250 since I bought it on sale, but I think it's a good deal even at its current price. There's no need to be on the fence. If you're considering purchasing this mattress, it'll serve you well. Just be mindful of the size, weight, density/firmness, and how to care for it.

updated on 12/21/18: still enjoying this mattress. I ended up putting on a kohls "big one" mattress topper as I like a soft bed. this mattress was a little firmer than I preferred as I noted in my first review. I read a few reviews saying they found the mattress stayed "dented" as they slept on it. I haven't found this, I weigh 170 lbs and the mattress refreshes its shape as soon as I move away from the original area. overall, still pretty impressed with this mattress. its on the firm side, but the topper I put on it has made it absolutely perfect and I sleep well, and yes, it does stay cool.Was a little hesitant to buy a gel memory foam mattress online, but after looking in all the stores and their prices, I figured I would take a chance. I am very pleased with my purchase of this king mattress. It is hard to comment on the plushness level as not everyone agrees on what is soft, hard or plush due to their personal taste. I was replacing another regular king foam mattress that I have had for 6 years. I cut it down to queen size for a guest bedroom as I found it so hot to sleep on. It was a great mattress, nice and soft, and I really liked it. But I am a very hot sleeper and was getting tired of waking up several times a night literally sweating (Im in FL). This mattress was put on a king platform bed with bungy boards for support. It expanded to 12" within about four hours and there was absolutely no odor as I had read some reviewers had a problem with this. It was packed very well, the box was a little beaten up upon arrival, but the mattress is packaged so well, this did not matter. I m in my late 50s and I had no problem dragging it into the house on a dolly and then dragging it into the room. Once I got it out of the box, I had no problem getting it onto the platform bed and removing the packaging and placing it to expand. I have slept on it for about 3 weeks now. At first I thought it might be a little too firm for me, I like a very plush mattress. But I decided to give it a chance as I could always put my old gel memory topper back on if needed. After 3 weeks I find it's not too firm, it's just right for good support for my back, but plush enough that I sink into it a bit. Once I move, the small indentation goes immediately back to its original shape. And I no longer wake up many times a night in a sweat. The mattress is not overly cooling, I find it just right. The side edges are firm enough to offer support if sitting on the edge. The cover on the mattress is beautiful and high quality. But I still put on a mattress cover just in case. Overall, I am quite happy with this purchase. Buying a mattress online can be intimidating as I am not sure what people do when they have to return a foam mattress. But this mattress is a keeper and I sleep so much better now.
