  • King Mattress
Size: King Style: 12 Inch Color: Gray+white
This is a great mattress and nice mattress, perfect size and thickness, no smell, easy to set up, and nice soft-firm ratio. I ordered a memory foam mattress king size because it was easy to have delivered. I did not expect it to be so comfortable. I thought it would be fine, but this one is really lovely. It has a great price point compared to conventional mattresses. Plus, its foam is perfect: you sink into it just a couple of inches, and it really supports your whole body with just enough resistance. The cover is super soft, and really substantial. This is really a good mattress for the price. I sleep well and it’s not too hot. I’ve had a really hard time finding a mattress that firm enough to support my back. Nothing to dislike the bed was amazing and comfortable! ... show more

  • Finally! Sleep I've been looking for!
Size: Queen Style: 12 Inch Color: Gray+white
275:365 10.02.2023 A bit cluttered. Since being in an accident in February 2022 I have tried 3 different mattresses without great success. I kept saying it will get better when in reality it hasn’t. At the tim3 of my accident we had a king head adjustable bed. We decided that it would be better to do split king (2 twin XL MATTRESSES) with head and foot adjustable base so that I could adjust to my comfort while my husband could still sleep flat if he wanted. I typically like a firmer mattress and he prefers softer and when shopping we found a deal we couldn’t pass up. I figured although the firmer mattress was just a smidge too firm that I would be ok. I didn’t want to complain because with not working we bought what was within a budget but yet met our needs. it got to the point that I was not able to sleep so I went in and explained what was going on and that it had been well over our 100 nights but I just couldn’t do it. The place we purchased from was very understanding and gave me a great discount on another mattress that was plusher and felt good but in time it was still just not right. Again, grateful and with my condition 100 nights just didn’t seem long ebough to really know. A month ago I finally decided that split king makes things difficult and also with the mattress still not being just right, I would browse Amazon for a queen size bed and adjustable base and just make payments for 6 months on something. Although I still wanted to keep the twin XL I had because it is perfect when Aunt Debi comes to visit and would be nice for overnight guests. So here we are 10.14.2023 I’m updating my book of 2023 and I can say don’t overlook shopping on Amazon for a mattress. I purchased the 12in Queen Sweet Night mattress and let it “set” for the 72 hours suggested before using and have ZERO REGRETS. I haven’t been this comfortable with a mattress since our 2006 purchase of our King size King Coil Visco Foam mattress that we had for 15 years. ... show more

  • Disappointment and regret
Size: Full Style: 12 Inch Color: Gray+white
This mattress did not expand to 12 inches. After 6 days it is still sitting at less than 10 inches. I even went so far as to use a small space heater to warm the room. The corners did not fill out at all and the mattress has a rounded shape that prevents all 4 sides from lying flat on the foundation. When I lay on the mattress there is some sinking in that I expect for a plush mattress. But, it doesn’t conform to my body like I expected. It’s more of a general collapse of the foam layer so that I am resting in a huge dip. I can actually feel it bottom out so I am laying on a very hard surface. Not great for pressure relief that sent me looking for a memory foam mattress in the first place. After having read thousands of reviews for dozens of mattresses, I’m so disappointed because I thought I found a winner. Before you buy this mattress, think of the impossibility of returning it. Even with a guarantee, how do you get this huge disappointment back in the box to return it? ... show more

  • Great mattress, great price
Size: Twin XL Style: 12 Inch Color: Gray+white
I was hesitant because I didn’t know the brand but I needed something quickly and this mattress had the earliest delivery date. Purchased it Saturday evening and received it early Monday afternoon. It was easy to setup and didn’t take long to expand. It is so comfortable. I like it better than the previous name brand mattress that cost much more. Would buy again. ... show more

  • Super comfy!
Size: Queen Style: 12 Inch Color: Gray+white
I bought this mattress after reading many reviews and doing a lot of research. For one, it doesn’t make you sweat when you sleep for lack of breathability like some mattresses do. It also doesn’t get hard as a rock if your room should happen to be cool. A regular sized sheet fits on it and I would rate it as being in the soft category for firmness. But not so much so that you sink forever into marshmallow land. It supports your back and hips and offers a good nights rest. I would say it’s a bed you look forward to going to sleep in each night. Comfy but do be sure to put a good quality mattress protector on it because one good spill will indeed wreck it. I bought the zip around kind here on Amazon and it’s prevented damage to the mattress. This one’s a keeper and I would buy again if I needed another mattress replaced. ... show more

  • Nice but not really plush
Size: Queen Style: 12 Inch Color: Gray+white
After reading all of the wonderful reviews about this mattress, I was so excited to get it. However, it is not as “plush” or soft as advertised and this seems to be a common theme for mattresses on Amazon. It did expand right away and had no bad smell and was easy to get all set up. At first, it seemed like it was going to be soft, but as we slept on it that night, we realized it was rather on the firm side. Good news is that it does not retain heat! All in all it’s ok, but will be buying a mattress topper to help with softness. For those that like more firm mattresses, this will be perfect for you. Did not help my occasional sciatica and woke up a bit sore. Nor did I sleep nicely through the night. Giving it time to break in more and hoping it doesn’t become anymore firm as some reviews here state. ... show more
