    • Perfect Short Queen Mattress – Cool, Supportive, and Great Quality
Size: Short Queen Style: 8-inch
I’ve been really impressed with this Cool Gel 8” Short Queen Memory Foam Mattress. It arrived compressed in a box, and once opened it expanded quickly and was ready to use within a few hours. There was very little odor, which was a nice surprise compared to other memory foam mattresses I’ve tried. The medium-firm feel is just right. It has enough support to keep your back aligned but still provides that comfortable memory foam contouring. It relieves pressure really well around the shoulders and hips, making it comfortable whether you sleep on your back or side. One thing I really like is the cool gel layer. Memory foam mattresses can sometimes trap heat, but this one does a good job staying cooler throughout the night. The breathable cover also helps with airflow and feels soft to the touch. The short queen size fits perfectly in RVs or smaller spaces where a standard queen is too long, and the 8-inch profile still feels supportive without being overly bulky. Overall, this mattress offers excellent comfort, good support, and great value for the price. If you’re looking for a quality short queen memory foam mattress that sleeps cool and feels supportive, this one is definitely worth considering. Highly recommend. ... show more

    • If you prefer a mattress that's not "firm"...
Size: King Style: 14-inch
Review Image by Bwater Evan Bwater Evan
For years we had been sleeping on an old inner spring mattress with an inexpensive 4" foam topper. It was VERY SOFT, so much so that getting out of bed was sometimes an issue. Plus I often woke up with shoulder or neck pain. FYI, I'm a side sleeper. And lately, my sleeping's just been lousy. I expect Covid-related anxiety is party to blame. Regardless I decided I wanted a new mattress. I decided on a bed in a box. I got one for both of my kids over the years and they seemed happy. Plus, there are very well reviewed products out there for way less than traditional beds. Lastly, return policies often seemed too good to be true (see more on this below). After spend days reading hundreds of reviews and watching videos, I opted for a Tuft & Needle Mint. It cost about $1K. Easy ordering, arrived promptly, set up easily, and looked great. It was rated "firm." Well, my wife HATED it. Truth be told, she didn't give it a fair try. She kind of said she wouldn't like it before it arrived, said she didn't like it after night 1, and after night 2 said she was up all night with back pain. FWIW, this mattress should have relieved her back pain, not added to it, based on firmness and the fact that she's a back sleeper. Didn't matter. Her mind was made up. It had to go. So I called T&N on day three and they were FANTASTIC. Refunded my purchase price IMMEDIATELY and said I should give it to a local charity or, failing that, give it to a friend, family member, or neighbor in need. The return policy that I thought "too good to be true" turned out to be 100% true. Good on them! I gave it to a family in a neighboring town that lost all of their possessions to a house fire. I ordered the 2.0 via Amazon because it was the more "plush" of the options and because of the literally thousands of positive reviews. Oh, the fact that the price was less than half of the T&N didn't hurt. It arrived in about 8-9 days (my only complaint). Very large box that I once again had to navigate to the second floor. Popped it open and enjoyed watching the inflating process (again). After figuring out which side was front and back we placed it in place and let it "breath" for a couple of hours. With chemical smell to keep me off it, I put a cover and sheet on it and slept on it last night. It's definitely on the plush side. I wouldn't want it any softer. But I actually found it more comfy than the 2x more expensive mattress that preceded it. "They" say soft is good for side and stomach sleepers (which I am) and they appeared correct. I only had one night on it but I'm sure it'll be fine for me. My wife joins me on it tonight and we'll have to see her reaction. Should she not like it I'll just get her a 2" topper for her side to make it softer. You can't see the actual mattress so I can't comment on its looks or fit and finish. The cover isn't at taught as the T&N's cover and the materials not as rich feeling, but it doesn't feel cheap. As a bonus, it come with two "bonus" memory foam pillows and though it did smell a little when I woke up my head was on one of them and not one of my "old" pillows. I can't speak to its return policy and hope I don't have to. But I am comfortable saying (pun intended) that this is a nice, inexpensive option for someone who likes a softer mattress. ... show more

    • Most comfortable mattress we've ever bought!
Most comfortable bed we've ever bought! Wow... soft yet firm. Felt like sleeping on a cloud. Very happy with purchase! The expansion and height were accurate. Great quality. We will definitely buy this brand again!

    • Good matress. Really thick.
Size: Queen Style: 10-inch
Its a little stiff (I did put it on a metal box spring), but I do think its comfortable, I just like a soft-med bed. I would say on a metal box springs, its a med-hard. I put it in my guest room as originally intended. It did take several weeks to get rid of the smell. I didn't try really hard, just left in the room with the fan on. I have had it several months now, and sometimes I will sneak into that room and take an afternoon nap or if I want to sleep alone for the night. ... show more
