This Simmons 10” Memory Foam mattress is replacing a decades old innerspring mattress in our guest room that was suffering from uneven wear, sagging, noise, and poor support. Its medium firmness is ever-so-slightly squishier than our 15-year old ‘extra firm’ memory foam mattress in the master bedroom, but in a good way. We’re using it on a box spring for now, just for the extra height, but this mattress doesn’t require a foundation; it can be placed directly on a platform bed or over support slats spaced at most 2” apart with a head-to-foot center support with at least one central leg extending to the floor. If the slats are farther apart than 2”, a solid surface like ¾” plywood must be used between the mattress and slats. Using any other type of inadequately supported foundation that doesn’t fit these specifications could result in damage to the mattress and would void the warranty (10 year limited). The mattress ships rolled up in a box and vacuum sealed in a large plastic bag. The double/full-sized one weighs about 60 lbs; so I was able to maneuver it around on my own, though it’s a good idea to recruit an extra set of hands/muscle if you have back issues. Included in the box is a plastic cutting tool, like a letter opener, that you can use to cut the bag open. Unrolling and removing the mattress from the bag was fairly easy; I recommend cutting a strip off near to the edge of the bag so that you don’t damage your new mattress. The bag can then also be reused to wrap up your old mattress for disposal, as this is required in many municipalities. After the bag is opened, the mattress starts to expand very quickly, and while you can sleep on it within only a few hours, it won’t reach its full height and designated firmness until about 24 hours later. However, even after several days, the final height of the mattress was slightly under the stated 10 inches by about ¼”. There’s also a bit of off-gassing initially resulting in a mild chemical smell that is part and parcel to all memory foam products. While I typically find that this smell disappears after a few days, after a week and a half on this mattress there’s still a little odor that is lingering, so I suggest keeping the door to the bedroom open and using an air purifier fitted with a VOC filter to help dissipate it more quickly. As for the sleep experience, it is wonderful. The medium firmness gives a little, though I wouldn’t call it plush; just enough so that my body makes a slight indentation whether I’m sleeping on my back, side, or stomach. I tend to change sleep position often through the night these days, and the mattress lets me adjust my body position as needed without making me feel trapped in a pit. For reference, I weigh about 125 lb, and this mattress does not have any weight limit. In fact, Simmons states that the foundation would give out first before any damage would come to the mattress. As for edge support, when I sit on the sides of the bed, it compresses about half its height, though it doesn’t make me feel like I’m about to slide off. I usually sleep pretty warm, so I was happy to find that the upper layer, featuring Climate Cool moisture wicking gel foam, helped draw away heat from my body, keeping me cool and dry through the night. If you are the opposite and like to use heating pads or blankets, just know that this is not recommended on memory foam mattresses as it can cause damage to it. There is a motion isolation layer between the memory foam and base layer that absorbs surface movement between sleepers that works really well, so you won’t feel the jostling and movement of your bedmate (or they you). The best part is that it is completely silent. With no moving parts inside and a solid/rigid foundation, nothing moves or squeaks and most movement on top is absorbed by the mattress before it ever transfers to the bed frame itself. The mattress ships with a cover over the foam that is not to be removed, as doing so will void the warranty. However, this cover isn’t waterproof nor considered a mattress protector, so if you want to guard it against spills and stains, you can add one over top. The existing cover can be spot cleaned with mild detergent and cold water, which works pretty well as mine shipped with a small black smudge that I was able to wipe off with a damp sponge. As for care and maintenance, the mattress is designed to never require flipping, though rotating is recommended to even out wear. Overall, this mattress provides me a great night’s sleep that leaves me feeling refreshed and energized the next morning. It is supportive with a decent firmness that’s neither too hard nor too soft, and it is compatible with many contemporary bed frames and foundations including adjustable bases. I look forward to using it for years to come and might just start sleeping in the guest room more often.

I'm reviewing the Twin size mattress for our teenage kid, who's very pleased with it. The mattress arrived in a box, packaged in vacuum seal. The box itself is fairly light and easy to carry upstairs. Once I cut off the plastic bag, took the mattress out of it before it regained much air. Because it arrived in the afternoon, left it air overnight. It appears it might take a full day to fully regain its normal shape. Once fully in-shape it's sturdy and fairly thick (About 10 inches). Like other memory foam mattresses, most of the mattress is 'standard' foam at the bottom of the mattress. Then there is a middle layer of sturdier material and the gel memory foam is the top layer. The cover around the mattress is thick and has a built-in zipper, and it feels very breathable. Like in every other mattress we have, we always add a mattress cover. After a few nights, our kid is happy to report that had good night sleep and the mattress is very comfortable, reminding of 'The Princess And The Pea' level of comfort, so that's a success. Although I expected a thicker memory foam, the end result works well, with a good balance between softness and support. Also note the mattress is made (Or at least assembled) I the USA. Also note that the foam emits some odor of the first few days. The is comparable to every other memory foam mattress we bought over the years, and other mattresses took a lot longer than this to stop smelling. It's not too bad after the first or two days however, and normal for this type of product. Once placed in the bed, it looks just like in the product images. Overall we're happy with this mattress, being thick overall and easy to unpack.

So we got this to replace a kids mattress. So far two of our kids have slept on it and are very happy. They keep taking turns. So like many mattresses these days, this one comes in a box. When yuo open the box the mattress is shrink wrapped quite well. The instructions walk you through how to unwrap it and remind you it can take a little time for it to fully expand to its full size. I have seen a few other posts on here about the mattress not quite reaching the full 10” but ours is the full 10”. The instructions also let you know that the memory foam smell can linger for a few days but eventually will go away. Honestly we did not notice any smells at all. The picture is one of our kids about 10 minutes after we opened it. He could not wait for us to even move it into the bedroom. Comments from the kids after several nights of sleep, they like the firmness and do not sink as much as they used to in the other mattress. So for now this is a homerun with the kids.

At first I didn't think I was going to like this bed. I had been used to sleeping on a mattress that was literally 50 years old. I sank into this the moment I laid on it. But, I've been using of for a number of weeks now and I'm really enjoying it. I look forward to going to bed because I can now sleep comfortably.

I love this mattress. It’s comfortable and supports your body. I was surprised of how much I would love it.
