    • A very comfortable mattress for the back and safe. A very comfortable mattress for the back and safe.
Size: King Style: 12"

I bought this mattress almost a month ago. What can I say, I am very satisfied. My back hurt a lot on the old mattress. It took me a long time to choose a new mattress, and I read a lot of reviews. I was very afraid to buy a mattress with fiberglass, but I also wanted to buy a mattress that was not too expensive, since I live in a rented apartment. Signature Design by Ashley Chime is a manufacturer responsible for quality. I'm still very happy with the mattress, I've lost the average stiffness, my back doesn't hurt anymore. The only thing I didn't check in height to make sure everything was in line, I bought a 12 inch mattress. I'll do it later and update my review. ... show more

    • Great bed at fantastic price!
Size: King Style: 12"
Great bed for the price! Very comfy, on the softer side not firm, bouncy have used for a couple of months now and very happy and would repurchase again for other beds, if you’re on the fence for this or a more expensive bed BUY THIS! Worth it!

    • Nice qualify, subjective comfort
Size: King Style: 12"
I bought this mattress for a rental and finally had a chance to sleep on it. The mattress is a very nice quality and I believe represents the description. However, I am a side sleeper and it was not relieving enough on my pressure points for a restful sleep. I am 49 and use to sleeping on a 100% memory foam mattress for the last 20 years. I think comfort is subjective and personal so I do believe all the positive reviews. Hopefully, it will break in more and my guests find it comfortable and restful. I am considering a memory foam topper 🤔 ... show more

    • Firm and very comfortable.
Love this mattress. I use it in my RV and it is a firm mattress that is very comfortable. The material is made of high quality and keeps me cool at night. The size is perfect and sheets fit on it nice and snug. I liked it so much I ordered another for the bed in my house. Definitely worth the money.

    • Good semi-firm mattress
Size: King Style: 12"
Great mattress. We really needed a new one, and really figured that out after a vacation while staying at an air bnb. The mattress there was so comfortable but no longer available on Amazon. I did some research and found this mattress to be as close to that one as possible. We previously had a nectar mattress that was pretty beat up and way too soft for us. My husband was nervous about this one being hybrid but I said TRUST ME. Some of the reviews said the mattress didn’t expand fully. I didn’t pull out a measuring tape, but it definitely expanded to a normal size thickness after leaving it out for 24+ hours. It fits perfect on our king size bed with no issues. It’s a tad bit firm, but the memory foam and built-in topper help keep it on the softer side as well. There’s no noise when getting on/off. It doesn’t seem to get too hot overnight. Overall, for the price the quality is worth it. Even if it only lasts a year or two, paying less the $400 for a mattress of this quality is a win-win for me. ... show more

    • Was great for 5 months… then suddenly awful
Size: King Style: 12"
Purchased in July of 2023, completely toast by May 2024. We got the mattress, set it up on a brand new Zinus steel box foundation and we let it breathe and rise for a while. It didn’t rise to 12 inches, but got to about 11 which was fine. There was no odor or anything like that. It was soft, but then firm once you were on it, which was exactly what we wanted. For the first couple months the mattress was nearly perfect. We slept great, it felt great, and we felt like we’d gotten a fantastic deal. We loved it - it was supportive and immediately helped my back pain. Then the foam near my head started going flat. The corners on the head side of the mattress started sinking and rounding off. We don’t even lay or sit on those areas, so that was baffling. And suddenly it was significantly less comfy, especially on the wife’s side. On my side, about a pillow of depth was lost where my pilllows go, so without a pillow my head was below my body.. So we rotated it in an attempt to keep my wife happy and maybe more comfortable and to get my head level. And within a week, the bed entirely collapsed at the feet, the end line of springs just rolled over and out. The wife is more miserable than before the new mattress and any comfort this bed had has been lost. I keep pushing the wonky springs end back into place to keep it looking normal, but this bed is DONE! It was such a promising start, but I would not recommend this mattress to anyone at any price. It’s just going to end up in a landfill. It lasted us about 2 months before problems arose, and those problems kept getting worse. Attempting a warranty claim, but not expecting much. UPDATE: Added video - checkout how the springs collapse with just a hand pushing on it. ... show more

    • Best Mattress I've ever owned regardless of price
Size: King Style: 12"
I've owned Saatva and slept on Purple, and this Ashley is the most comfortable mattress I've ever had. I'm completely blown away by how comfortable/affordable it is. I tend to sleep on my back, sides, and stomach and this is the only mattress I've ever owned where I didn't wake up with soreness issues from at least one of those positions. I bought the 12" version because I'd read a review of budget mattresses that specifically reviewed the 12" version and gave it a really good review. Totally deserved! The only thing they knocked it for was they said it is not good at isolating motion vibration, but honestly when my girlfriend sleeps over (and she is a bad fidgiter) there is very little vibration transferred to my side. ... show more
