Review: Surprisingly Supportive for 5″, Great Firm Feel & Amazing Price - I was a little unsure about a 5" mattress, but this one really surprised me. Even though it’s thinner, it feels just as supportive and comfortable as thicker mattresses I’ve owned. It has a slightly firm feel, which I personally prefer, and it holds its shape really well. With some 5" mattresses, you can feel the platform or slats when you sit or lie down but that’s not the case here at all. This one feels solid and well-made, without any sinking or bottoming out. I’ve been sleeping comfortably and wake up feeling well supported. The price is phenomenal for the quality, and it honestly made me rethink traditional mattresses altogether. I’d never go back after this. It’s been a perfect fit for my low-rise platform bed, and I’m very happy with this purchase.
Review: Great quality for price / ease - I have the 12" and the 6" for myself and my toddler. They are both on the firm side, but not "like a rock" as other people have mentioned. If you're used to a super soft bed it will likely feel pretty firm initially, but it gets more comfy over time, in my experience. I prefer to let mine sit in a room to get their shape back for a day or two before use. I thought I liked a very soft bed but it turns out I like the medium-firm memory foam better. There was a slight off-gassing smell the first 24 hours, easy to open a window and turn a fan on. These are incredible quality mattresses for the price, door delivery, and ease of set up.

### ⭐⭐⭐⭐⭐ MMMMmmm Bed... Comfort, ease, and great priced
*by S***N on August 15, 2025*

This mattress is amazing and the cooling gel, medium firmness is so comfortable. I’ve used this brand before and have never been disappointed. Every time I’ve recommended it to friends or family, they’ve loved them too It’s super relaxing and supportive, and I’m getting good restful sleep again after sleeping on my couch from Nov ng and accidently destroying my 7 year old previous Zinus. The price for the quality is outstanding and makes it even better. If you’re looking for a mattress that delivers comfort, reliability, and value, I highly recommend this one. However, if you do prefer a more soft one, this one does say medium firm, but I think it is a little closer too firm and there isn't a whole lot of sinking in it, but there never was in my previous one either even after 7 years, and at that age that truly shows it's durability level. I also have dogs that sleep with me and act rambunctious on it. I would say for the price, the ease of setup and the tiny box they send it in, the comfort level, and the durability level I don't think you can do better and I have even slept on those $10,000 mattresses.
