  • Amazing budget mattress
Size: King Set name: 12"
We bought this mattress when we moved into our house in December 2024 and upgraded to a king bed. I waited until now (July 2025) to leave a review so that we could give it a good amount of time and see if it held up. It does. We love this mattress. It’s the perfect firmness (not too soft, not too firm). We both sleep in various positions and it’s comfortable for all (back, side, stomach). We’ve experienced no sagging or anything so far. We don’t spend a ton of time hanging out in bed, mostly just sleeping so maybe it would be different if you spend a lot of time in your bed. It fits our bed frame pretty good, there’s a couple very small gaps. As I recall, when we got the mattress, it took a day or two to fully expand. There was no odor at all. I honestly don’t think you can beat the price - I think the mattress over delivers for the cost of it. We’ve been really happy with it. ... show more

  • Durable for Amazon Bed in a Box
Size: Queen Set name: 10"
Hello. I have had the mattress for three years now. It is a firm mattress, I keep a 4 inch memory foam topper and a down cover for the mattress, and those keep it cushy and clean. In the three years, Ive only had to replace the memory foam topper. I have not had issues with it falling apart or sagging in the three years I have used it. I just purchased a new bed frame as well. I feel it has outlasted its counterparts as expected and is good, and comvenient bed in a box for the price. ... show more

  • Quality at a great price
I’m pleasantly surprised by this mattress. I’ve slept on it for a month and .wasn’t expecting this quality for the price. I purchased a queen and gave it the full 2 days to unfurl and do its thing. I would say it’s firm yet still a little plush. There’s no feeling of sinking and the sides don’t slope if you sit on the edge. I can put something down on the surface and it won’t spill or really, move at all. I’m guesstimating a good 3-5 year life but that’s exactly what I wanted. The only reason I took off 1 star is because it NEEDS handles. It is heavy. I am very happy with my purchase. ... show more

  • The mattress is really thick. You will need deep pocket sheets for it.
I wanted to wait a little bit before I reviewed the mattress. Get over the phase of transition from the old one to the new one, and see for sure how the mattress affects my sleep quality. I can't even tell you how much I love this mattress. I use to be tired all the time, I had back pain so bad that I could barely stand for long. My energy level is getting better and better each day as I get a MUCH better quality sleep than I was before. I look forward to going to bed now, instead of avoiding it as much as I could. My back pain has significantly improved!!! The mattress is so thick and soft! I sink right in and am out like a light. That never happens for me! I have insomina! But now I fall asleep before my husband sometimes! I love this mattress so much. ... show more

  • Medium firm, used more on day bed-sofa style
Size: Twin Set name: 8"
Bought the 8inch for a day bed. Make sure area you are opening package in has enough room for mattress to open up. I have bought this brand of mattress before and I have liked it, this is the 3rd one to be purchased. This one is more of a medium firm, but I am also using in a space that would normally be used for a sofa. I have only had this for about a week so far, but it is well liked. ... show more

  • Was great for 5 months… then suddenly awful
Size: King Set name: 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

  • Only buy the 2 thicker versions, the 8" isn't good
Size: Full Set name: 8"
I've moved a lot & have had to purchase 3 of these same mattresses in 5-yrs. The thicker mattresses are the best I've ever slept on, including a $1,500 mattress I once owned. Here's my breakdown: I bought the 12" first. Blissfully comfortable, but I'm a small girl & at 70-lbs (more than 1/2 my body weight) could barely get it inside my door, out of the box & into the bedroom, then on top of a frame... took 1-1/2 hrs. I also couldn't easily turn the mattress with use... took 20-min for me to do it alone. For that reason alone, I next bought... ... the 10" version. Same as above with comfort, but at 60-65 lbs, same thing. Hard for me to set up & move around without back strain. Then, I got this 8" version, mainly as it was cheaper & I know I'll be leaving it behind again next year. I hate it. I like a supportive mattress with not much give, but love pillow/soft tops, like these mattresses, for that reason... firm underneath, soft support on top. This mattress is about 50-lbs, so easier to move, although it is a bit flimsy & catches on the carpeting & begins to fold in half... it's a pain in the ah... soul... to move around alone. It's mid-level to soft, so if that's what you like, you'll love it. As an example, you could fold this mattress & tie it up if moving... with 2, you'd be able to roll it & tie down. With the 10-12" mattresses, that's not possible. Additionally, it is not comfortable at all to use the bed to sit up & watch movies or work on the computer, as it's too soft to support the lumbar area of the back & I get back pain quickly... I did not have that problem with either the 10 or 12". So, if you need this for a kid, guest room or someone who likes a softer mattress (my senior mom would love it), it's great. I can't imagine 2 people could sleep on this comfortably for any length of time, unless they're house guests because there'd be too much give. Can't wait to leave this behind... my heart usually breaks when I have to discard a brand new mattress... but, I'll bet I could roll this one up & haul it to the trash chute with a dolly on my own. I'd say skip it, if it will be your nightly bed. 3* out of 5, cuz it's still a good product... but, I really give it a 1*. I'd continue to buy this brand cuz it's great, but never a thinner mattress. ... show more

  • Plush, like a cloud.
Size: King Set name: 12"
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. ... show more
