I was previously unaware of the concept of a mattress in a box. Upon visiting the Wayfair store, I had the opportunity to examine the mattress, having seen it advertised online. We proceeded to order it through the website due to the complimentary delivery service. It subsequently arrived packaged within a box. ItIt was quite heavy, so you will require assistance from another person to move it to its intended location. We have unraveled it, and as less than 24 hours have passed since then, this is its current appearance. Therefore, I will likely wait another 24 hours before placing it on the bed to ensure it has reached its maximum fullness. However, considering the price, we are quite satisfied with the purchase so far, and I will likely provide a follow-up review later.. Sabrina. Atlanta, GA. Sat Sep 12 2026

[This review was collected as part of a promotion.] As you can see, the room hasn't been updated in 10 + years including our mattress.. this has been an actual game changer!!!! It feels really nice, medium feel, i dont feel like i sink in but it also doesnt feel like a board. It almost curves to my body and I have been getting such a great night's sleep with this mattress!!! I am a plus size person and between me and my husband its well over 550+ pounds of weight but it has been working out for us. We've been using this mattress for almost 60 days and it feels the same as the first day we got it! Comfortable, doesnt sink for our weight and so far I love laying in bed without getting some type of soreness from sleeping "wrong". Its definitely the mattress you use that causes this.. in love with our new mattress!!!!. Ashleyr. Mon Oct 12 2026

We got the 14" mattress. I love the 800+ individually wrapped springs, and the fact that it is fiberglass-free, and has CertiPUR-US foam, and OEKO-TEX certification. The mattress also feels really nice and supportive, but also very cushiony on sore joints. I do not think the " reinforced edge support" is anywhere near as supportive as the "integrated mattress edge support" our last mattress from Wayfair featured. The last one we had was the Wayfair Sleep Medium Hybrid Mattress, and you could sit on the side of that one without it sinking down more than just a tiny bit. I liked that feature a lot as it gives you a more stable surface to sit on to put on shoes, etc. Thankfully we have a bench at the end of our bed, because this mattress edge sinks down quite a bit on the edge. (And NO, I have not gained weight since we had the last one.) My husband and I both miss that extra structure at the edges of the old one, but this mattress does feel very nice. Overall we are happy with our purchase. I would have given it 5 stars if it had had the same edge support as the previous mattress. Update: It's now been 5 months that we have been sleeping on this mattress and it is sagging. I wish I'd never bought it. We rotate our mattress every 4 months. We are not obese people, and frankly even if we were, the mattress is supposed to support 880lbs, and my husband and I aren't even half that added together. Don't buy this mattress.... Sherri. Jefferson City, TN. Tue Sep 29 2026

I’m very happy with this purchase! It’s incredibly soft and comfortable while still providing a nice level of firmness and support. I’ve been sleeping really well on it. The only minor issue is that all four corners seem slightly compressed or sunken. I initially thought they would fully expand and return to their normal shape over time, but they still seem to be that way. Aside from the corners, I’m very satisfied with everything else. It’s comfortable, supportive, and I’ve been enjoying it so far. I would definitely recommend it!. Anonymous. Fri Oct 16 2026
