Description

Classic Brands Ventilated 8-inch Cool Gel Memory Foam Mattress is the latest technology in memory foam mattresses. One layer of 2 inches of gel-infused memory foam draws heat away from your body and allows breathability. The second layer beneath consists of 6 inches of high-density memory foam that conforms to your body providing support, pressure point relief, and proper spinal alignment for a great night's sleep. Perfect for kid’s rooms, college dorms, and guest rooms, this mattress is a great value for any room in the house. The Cool Gel 8-inch Gel Memory Foam Mattress combines two leading sleep technologies at an incredible value. Gel-infused memory foam keeps you cool during sleep and body-contouring memory foam reduces pressure points and properly aligns the spine. Gel draws heat away from the body and creates a cooler sleep surface and aids in preventing excessive tossing and turning so you can get a more restful night's sleep. The feel of this gel memory foam mattress is medium firm - slightly similar to that of a traditional firm mattress and it’s adjustable base friendly. Benefits of Gel Memory Foam A gel memory foam mattress can support each part of the body evenly and individually. Gel Memory foam slowly and automatically adjusts to your body weight and temperature. In addition to the slow, conforming response, gel memory foam offers complete, luxurious and stress-free support. Additionally, when you do move in bed, memory foam gently 'fills in' and reshapes itself to your new sleeping posture, cradling every contour of your body. The Latest Gel Memory Foam Technology Gel Memory Foam is a unique material that infuses gel particles into visco-elastic memory foam, creating a cooler sleeping surface. Gel memory foam is more porous or open than conventional foam meaning the cells are interconnected unlike closed cell foam; thereby is more breathable and comfortable than higher density visco-elastic foam. The open-celled physical structure of our foams is self-ventilating. Air travels throughout the material and dissipates body heat regulating your body temperature. Why Buy a Cool Gel Memory Foam Mattress? Cool Gel mattresses with gel infused memory foam disperse body heat and create a cooler sleeping surface while retaining the pressure-relieving properties of traditional memory foam. Tossing and turning are dramatically diminished and disrupted sleep patterns are greatly eliminated so you can sleep longer without moving and enjoy the benefits of a deeper, more restful sleep pattern. CertiPUR-US Certified Classic Brands gel memory foam mattresses are CertiPUR-US Certified. The CertiPUR-US program is a voluntary testing, analysis and certification program for flexible polyurethane foam used as a cushioning material in home furnishings such as adult mattresses, crib mattresses, upholstered furniture and some accessory comfort products. Certified flexible polyurethane foams have been independently laboratory tested. Get it Right the First Time It is also a good idea to know the size and the height of your mattress ahead of time to make sure you are ordering the correct size. Keep in mind that you should combine the height of your bed frame, foundation, or adjustable bed base with the height of your mattress to get a gauge of the how tall your sleep system will be.

  • If you prefer a mattress that's not "firm"...
Size: King Style: 14-inch
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

  • 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

  • great mattress for a great price
Size: Queen Style: 10-inch
Great mattress — this is actually the second one I’ve purchased from this brand. The first was a king size that I’ve had for years and it has held up really well, which is why I came back to buy a queen size for my kids. It’s comfortable, supportive, and arrived in great condition. Setup was easy, and it expanded nicely. Knowing how long the first one has lasted gives me a lot of confidence in the quality. Very happy with this purchase and would definitely buy again. ... show more

  • 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

  • Cheap price to pay for a lifetime of good sleep
Size: King Style: 14-inch
This is my 2nd bed I bought from them, moved up from queen (had the queen for 6 years and worked like new) to king recently and it's still the best bed we've had, all my children like to sleep on it and my blue collar husband feels well rested after sleeping on it, it molds to your body so it is very comfortable and with regular beds I got woken up constantly in the morning from my husband getting out of bed but this bed is firm enough to not even feel when someone gets up or from movements, the price is worth the years of rest and comfortable sleep that is to come ... show more
