Review: So comfortable—we bought it twice! - We have this mattress in our guest room and have always gotten compliments on how comfortable it is, so when it was time to replace our old mattress in the master bedroom, we ended up buying the same one again. I am SO glad we did! Our old mattress was extremely worn out and I would sink into certain areas, so I wasn’t getting the support I needed. I had trouble falling asleep, staying asleep, and would often wake up with sore back muscles or even muscle spasms. This mattress has the perfect amount of memory foam for me. It’s not too firm, but it still provides the support I need, and it allows for enough movement without disturbing my partner in the middle of the night. Since switching to this mattress, I’ve been sleeping so much better and waking up feeling much more comfortable. I’ve only had one morning where I woke up with the same kind of soreness, and that was related to a separate health issue rather than the mattress. We absolutely love this mattress and would 100% buy it again! (Even though we did already 😉)
Review: Good For Price + 1 year update - I would definitely say this mattress is a medium firm. I was a little disappointed because I was hoping it would be softer. As some other reviews noted, it does sink down a lot when you sit directly on the side. That being said, my partner and I both lay on the bed without it sinking or feeling uncomfortable. We are both 200+ pounds and it is very comfortable to lay next to each other. In fact, it feels more comfortable the longer you lay in one position, almost like it makes a mold around your body shape. When you get up, it goes back to its original shape. One great thing about this mattress is that it does not shake or bounce very much. My partner tosses and turns all night and it used to keep me up, but I don't feel him moving with this mattress. He can flop down on the bed and it doesn't disturb me at all. It does hold in heat and can get pretty warm throughout night, so I would consider getting a cooling mattress pad. I let it expand for 4 full days and it expanded to 11.5 inches so I was semi satisfied with that. All in all, I don't regret buying this mattress and if you are on a budget, it's a great option. If anything changes over time I will come back and update this review. UPDATE 1 YEAR LATER: This mattress has held up. There's no significant sagging, sinking, or other wear and tear. And like I mentioned above, my partner and I are both 200+ pounds. The side sinking has not been an issue over the past year, or maybe it firmed up more over time, but I honestly haven't noticed it after the first month. I would definitely buy this mattress again. I originally gave the mattress 4 stars, but I'm updating it to 5 because of how well it's held up.

### ⭐ Inconsistent firmness, but when firm they are great
*by G***H on November 2, 2024*

I’ve ordered this bed probably 6 times now. 3 times I’ve had issues with the order. Summary: if you happen to get one of the firm ones they are amazingly comfortable and a good price. As well as long lasting as my 2016 one is still good as new comfort wise. That being said there seems to be some decent quality variability issues where you might get a bed that might as well be a soft couch cushion. Worth the price when you get one of their firm ones. Not sure how to avoid this without returning and rebuying until you luck into the good ones. Quality/Order timeline: 2016: Ordered Queen 12 inch bed for myself and it said delivered but was not there. Reordered after refund and it was an amazing bed. Very firm and comfortable. And even today it holds up as my guest bedroom mattress. I’ve had multiple people comment on how good it is and my mom even got one after this after she loved it (from me). 2020: Bought 2 more 12 inch queens for my family’s house and they were great. 2021: Bought 1 for my brother who lived with me for some time and when it was delivered it was really soft. Like the softest bed your can find and the edge support was terrible. I have no idea how the original firmness could change so much but I thought it was a fluke so I returned and reordered through amazon. The replacement was firmer but still not as firm as original. We decided to keep it as he was not picky. 2023: I order my mom a king 12 inch for her birthday. It arrived great and was super firm like the original. She loves it. 2024: With my mom’s success I decide to upgrade my bedframe and get a king myself. The mattress they send me is embarrassingly soft. If I sit on the edge I sink all the way down to my bedframe laying in the center is still not comfortable but not as bad as the edge. I decide to return it to Amazon to rebuy it as I assume it’s a quality issue. They send me another and it’s the exact same thing, really soft. Sincd then I’ve had trouble sleeping, neck pains, and because the top edge sags it makes it harder to sleep right with reflux since my head is often tilted down a bit. The edge support is absolutely terrible on the new 12 inch king I got and the center is still not as firm as the original one I bought or my moms recently. I decided to return it this week. I know zinus/amazon will take my king back again and let me rebuy but it’s a pain each time to unbox, try out, and return. Not to mention they almost certainly throw away the ones I send back. So unless zinus can guarantee the firmness of another order, for the sake of avoiding waste and effort I won’t buy this mattress again. It’s a shame as the original one was my absolute favorite mattress.
