I've been using this full-size hybrid mattress for a couple of weeks now, and honestly, it has exceeded my expectations. The combination of memory foam and innersprings offers the ideal balance of softness and firmness. It contours well to the body without sinking in too much. I was surprised by how easy it was to unpack: it comes vacuum-rolled, inflates in a matter of hours, and didn't have a strong odor like other new mattresses. From the first night, I noticed the difference: I no longer wake up with back pain and I barely notice my partner's movements. Plus, it stays cool all night, which I really appreciate since I tend to sleep hot. I definitely recommend it if you're looking for a quality, comfortable, and reasonably priced option. It's worth every penny!

Finally a good night sleep. Very comfortable mattress. Medium firmness. It was easy to take out of the vacuum sealed bag. You should leave it 72 hours before using for the it to expansion back to its normal size. It is very comfortable and have good support for back. Good functional and comfortable mattress for the price paid. Definitely a good value for the money. I guest the only question would be how long would it last before needed to purchase a new one .. only time will tell. I will put in another review after few months of use.

Honestly, I was not expecting the extra softness I got with this mattress! It’s vey plush, soft, and thick. It instantly perked right up out of the box. Like who knew a mattress in a box could be so warm and welcoming lol By the end of the night it was already at its peak height. It fluffed up so quickly. It’s so nice to find an affordable mattress that’s actually comfortable. We just purchased another for our spare bedroom!

Bought this bed for my adult son’s former childhood bedroom. It was a great price and the thickness of this mattress is nice. The mattress inflated beautifully and seems comfortable. My biggest concern with buying a condensed mattress on line was side stability. The sales material claimed to and provided pictures of stabilized edges. The edges are reinforced on the upper part of the mattress, up to about where you would sit to get in or out. However, after that, the side and bottom edges are soft and you slide off it you try to sit anywhere on the end of the bed. I am waiting for a guest to test out sleep-ability. Gas the sides been reinforced all the way around, I would have given it five stars.

I wish I would have taken a pic when I opened the box and released it from the inner packaging but I didn't. However, this mattress was at its full depth within 12 hours. My mother-in-law said, "This is the most comfortable mattress I have ever slept on" and she sleeps full nights without waking up in discomfort as she has with her previous mattresses. It is well made, no odor, not too firm and not too soft. She describes it as a "cool sleep" so I'm assuming she's staying cool during rest. Ot was packaged well and honestly we couldn't be happier.

I bought this mattress for my guest bedroom for those staying with me after my surgery. My first guest has already told me it’s extremely comfortable. When I sat on it after opening and leaving it for a few days to regain its shape I noticed the edges are a little soft so I wouldn’t recommend it as a stand alone mattress but it’s great on a bed frame and I bought comfortable cotton sheets so the whole set is working for my first guest even better than expected.

If you like a firm mattress this one rides more on the line of extra firm, in my personal opinion. I wasn't really sure if a firm mattress was a good fit for me and my husband but so far it is good. We are heavier people so I thought getting a firmer mattress would help with some longevity, only time will tell lol. I was very impressed with the quality! Our old mattress was 1700$ (lasted 6years and similar construction to this mattress) and I was much more impressed with this budget mattress and its quality for the price. It also had lifting straps, absolutely loved this feature however when we went to move the mattress into the bedroom after the 72hrs we broke both the bottom straps, good feature but not heavy duty! For the price and the quality, so far it is definitely worth it! Also wanted to add, if you are someone who rotates your mattress, I don't think this one is a rotatable mattress due to how it is designed.
