Modway Aveline Memory Foam Bed Mattress Conventional, Twin,Firm, White

I've sleep on this mattress for 6 years. Never a problem. Flipped 3 or 4 times during that period .Just went from a full to queen size. Will be ordering same mattress in queen.

Modway Aveline 6-inch twin mattressBeing disabled, I spend about 23 hours per day in bed, thus putting nearly 3 years worth of wear on bedding per year. For the last 7-8 years I've been on a 4-inch memory foam pad on plywood, and it was good until the last year or so, when it finally started breaking down and bottoming out, giving me sore shoulders, hips, and lower back (200-pound side-sleeper). Time for a new mattress!I read all the Amazon reviews on several 6-inch foam mattresses, and picked the Modway Aveline because it has the lowest negative reviews. It's a bit more expensive than some other brands, but well worth it. The cheaper 6-inch mattresses seem to use less memory foam and more base foam, but the Modway 6-inch uses 2 inches of memory foam on 4 inches of urethane foam base (measured at corner). This gives it both firm support and a medium-soft top.Firmness: Reading the reviews, I expected it to be very firm, but after using it I'd call it medium. I was pleasantly surprised to feel shoulders and hips sinking in just the right amount. The first night I slept 17 hours and woke up with no shoulder, hip, or low-back pain. It's very comfortable!When you un-bag it, the foam rubber expands instantly, but the memory foam layer takes 24 hours or so, as expected. The measured height after 24 hours was about 6-3/8 inches.Cover: The nice zippered cover is tight enough to round the edges and corners, and smooth enough to make stretching your fitted sheet easy. The bottom of the cover has a zipper and little rubber non-slip dots. The cover material is nice, but not as heavy as the covering on the typical innerspring mattress; i.e., it's thicker than a bed sheet, but thinner than upholstery material. You might want to add a mattress protector for kids or night-sweaters."Cooling" gel: I didn't find the "cooling" gel-infused memory foam any cooler, or warmer, than regular memory foam. It's pretty warm but not uncomfortably hot. It's definitely a little warmer than plain polyurethane foam or innerspring mattresses. As with any mattress, you'll turn less and sleep better if you pile on the heavy covers and keep the room cooler (68-70).Chemical smell: When I first un-bagged it I stuck my nose right in it. There was a chemical smell; it smells like when you open a can of latex paint (not surprising, the mem-foam is latex). It did not stink up the room. The first night in bed I could fan the covers and just barely smell it, and by the second night there was no smell at all. Latex is a natural product, so don't worry about it.The base foam makes it rigid enough to stretch your sheets, and it's so lightweight you can start your fitted sheet over the corners, flip it over, stretch and finish your corners, and put on 4 elastic sheet grippers. I used Bed-Band brand grippers with Amazon Basics microfiber sheets (standard fitted sheets are made for thicker mattresses, so it's a good idea to use elastic gripper bands with fitted sheet on a 6-inch mattress).Foundation: I read many questions about what to put under a foam mattress -- slats, box-springs, etc., many with bad answers. The reality: all foam mattresses need continuous decking under them. You can use a regular bed frame with box-spring or hard-top box-foundation; or slats with plywood or hardboard; or a steel box-spring-replacement frame such as the Zinus SmartBase (which I used), again with plywood or similar on top (I used eighth-inch "tile-board," a hardboard with glossy white melamine coating), screwed to the Zinus frame with 4 drywall screws, then covered with a bed-skirt. You should NOT use a foam mattress on slats only -- it'll sag between the slats, and you'll feel them. The manufacturer says slats need to be less than 3 inches apart, but if you're gonna use that many slats, you might as well use fewer slats and plywood (quarter-inch grade A-C sanded), or Masonite hardboard (no splinters), over slats spaced 7-8 inches.How long will it last? I've slept on various foam rubber most of my 58 years, and even the firmest poly-foam breaks down and sags in the middle after several years, and since this mattress is two-thirds PE foam, I'm expecting to get about 5-8 years out of it. We'll see.Recommendation: If you like a firm-support mattress with a medium-soft top layer, you'll love this one. It's much lighter and more comfortable than an innerspring mattress, and is one of the better dual-foam mattresses.If I had to buy again, I'd probably get the 8", just because it'd last longer and be cheaper in the long-run.Disclaimer: I paid full price and received no compensation for my review. I hope it's helpful. Nitey-nite!

The best. Very cool and comfortable. Easy to set up.

We had this mattress for over three years. One of us considers it the best mattress we have ever owned, the other of us thinks it’s a tad too firm (totally fixable with a foam topper naturally)We ended up having to chuck ours after discovering mold on the underside which brings us to your first need to know:If you are just laying this out on a flat surface like a floor or a bed frame that has no slats just a flat piece, and you live in a hot/humid area, condensation can and WILL build up on the underside leading to mold. Disgusting. That being said, our solution is to lay it some of those rubber mats you see at swimming pools. We bought a set on Amazon and they provide plenty of airflow without adding much height. It would be best to research on your own ways of properly “framing” your mattress and consider airflow to the underside when doing so. This is essentially a big heavy sponge that WILL collect water and WILL get funky if you don’t actively work to prevent this.Second Point: you can not “flip” this mattress as the cooling memory foam topper is only on the one side. We found changing who slept on which side helped with sagging/softer parts.Third point: the current Amazon description says the cover is removable however the tag on the cover says it isn’t. It is zippered all around and I went ahead and removed it anyway (such a rebel I know) and washed/dried on delicate. The fabric did not shrink and I was able to re-zip because I left the bottom half where it was under the mattress. I’m not sure how well it would go for you doing both at the same time as this is a big floppy thing and not easy to work with. If you tried to do the underside cover it would be tough. I did get itchy/coughy because of (what I’m gonna assume) is some sort of fiberglass wrap that is on the mattress interior.... which I’m also assuming is the reason for the “do not remove cover” on the tag. It wasn’t a big deal at all... and I would’ve been a happy camper with my freshly washed mattress cover had it not been for the untimely discovery of mold.... seriously it was bed time. Worst possible time to discover your mattress is crap.Anyway I would suggest buying an additional mattress cover/protector to save all that hassle. Then you can remove or toss as you please and not need to fight the zipper and heavy mattress.Sheets wise: buy yourself some stretchy sheets. You can thank me later. Standard queen size works fine.Despite the mold issue we went ahead and bought this brand and size AGAIN because we knew it was comfortable and had served us well. It has sadly gone way up in price since we first bought it, but still a good price for a comfortable mattress and... well the whole world is going up in price so what are you gonna do?

I was moving into a new bedroom and decided I wanted a king bed this time around. I looked around and decided I wanted an extra thick mattress. I found this one and there weren’t that many reviews for the 16 inches, King (the one I got) but I decided to take a chance. I’m writing this review after almost 3 weeks so I could be totally honest in my review. AND ITS COMFYY. I seriously feel like a princess on this bed it’s great. I will say the bed is HEAVY. If you live alone I would advise you just pay for the bed to at least be brought into the room you’ll be sleeping in, because it’s a workout just unpacking it to put it on the bed frame. It fits my king sized bed frame, but because it’s so thick it pushes into the beams a lil bit. I personally don’t find it all that hot to sleep in, but if you like to stay cool it might take some getting used to, just a heads up. All in all it’s a really great mattress, it expanded to pretty much full size, around 14.5 inches in just one night, so I was able to sleep on it the day it came. The next day it hit the full 16. I don’t normally review stuff, but I thought I’d do so for my new bed frame and mattress. It’s a buy from me!!
