I have had this bed almost a month. I wanted to wait some time before writing a review on this particular purchase because I am a BED SNOB. I had my last bed for 8 years and it was time to go. It was a dream 8 years ago but now.. I woke up in pain everyday. Stiff, achy joints. My hips hurt so badly. My fiancé is a giant, 6'8, who also has back problems and we were ready for a bigger bed. I searched and searched and landed on this purchase. I will be frank.. I was worried about purchasing a mattress without first trying it out. I ordered this one and waited. The day it arrived, UPS didn't want to carry it up my apartment door so I was left to figure it out. Let me say this, this bed is NOT LIGHT and will require 2 or 3 people. Me and someone who lives in my complex helped me carry it to my third floor apartment. My fiancé was not home at the time and it was raining very heavily which was running into the first floor front door where my bed was and I didn't want it to get wet. He was coming down just at the right time. We were out of breathe and I'm sure that's the last time that poor fella helps someone again. It was NOT EASY. Got it inside and waited for fiancé to get home to throw away old bed and help me set up the bed frame and bed. I decided with a metal platform bed frame so no box spring needed. My other mattress I could lift and fling around with ease. This one.. Not so much. It took awhile to fully come to life, and it's a little small on my bed frame. I bought a king mattress, bought my king frame from Wal-Mart. Okay, on to the actual comfort review. This mattress made me stiff and more sore the first week. I was so upset but I had read that with a new mattress and sleeping on a previously unsupportive mattress you would have some discomfort. Your body is not used to being supported. It also needs to break in but once it's broke in.. Let me tell you! All that hard work lugging this mattress up the stairs was worth it! It hugs me in the right places. It's plush and comfortable. I have a mattress protector on it and it's not hot. I also hardly feel my fiancé move around at night or get out of bed in the morning.. And same for him. I'm up a few times a night to feed our baby and he doesn't feel me get up. Once this mattress is broke in it's quite comfortable. My son has asked for one, he's 8, because it's so comfortable and he now hates his bed. I've been considering getting him one as well. For being a cheaper mattress, it really is worth it. I will try to remember to update this in 6 months. I'm hoping it will last as long, if not longer, than my other mattress.

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.

I’m a 265lb dude, and this bed is comfortable! I have the king size for me and my wife and we’re both asleep quickly! We had to let ours air out for a day but well worth it. I currently have a metal frame that I used for a foam mattress before but I would recommend something with wider supports like wooden planks instead of bars otherwise it’ll sink In between the bars. Not crazy but it definitely weakens the support you feel so for sure get a good supper maybe even lay wooden boards on your metal frame. Anyways this is a very good mattress especially at its price point!! It comes delivered like a traditional foam mattress rolled up. Just cut the bag open and it’ll depressurize and unroll. The king size is a hundred pounds so make sure you have help if you’re not strong enough to lift and move!

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.

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 🤔

I’m not sure if my old mattress was that bad that it made this mattress feel like a dream! My Mom has this same brand mattress at her house and I love that bed but saw mixed reviews and was not sure if I should purchase. Totally worth it!

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.

This is a perfecrly fine bed. If you are in need of a decent, cheap bed, then you will not be disappointed. I am coming off 2 super delixe beds to this one. I have been heard to say, 'A bed is a bed', over the last year. I wasn't going to shell out thousands of dollars again for a mattress, so I got this beauty. It came rolled up and you have to let it 'unroll', for 2 days after you open it. At which time, you cannot lay on it, step on it, let your dogs play on it, or your children roll on it. This is a King sized mattress, so that was difficult to pull off. But, once that's done, it is fairly heavy and quite sturdy. It is as advertised, but that is not very thick to me and the first night I felt like I was sleeping in a foxhole compared to my other bed (for those kids who don't know, a foxhole is where soldiers used to lay low while battling the enemy, before we had drones. Just watch Wonder Woman, you'll see.) I finally had to put an old eggshell foam topper on it to be really comfortable, but now it gets super hot, so I have to buy a cooling type topper. On the whole, you get what you pay for, this mattress is worth every penny, firmness is perfect, it didn't smell bad, set up easy enough. Just remember to also buy a topper for superior comfort. And a happy slumber to you!
