PayLessHere Twin Size Mattress,6 Inch Gel Memory Foam Mattress in a Box,Medium-Firm,Pressure Relief&Temperature Regulation,CertiPUR-US Certified,Fiberglass Free，White

I first bought the PayLessHere 12 Inch Gel Memory Foam Full Mattress a few months ago, and it completely exceeded my expectations—amazing quality, super comfortable, and such a great price. Originally, it was for my daughter while she was still living at home. She loved it so much that when she moved into her new apartment, I decided to get her another one of the exact same mattress to take with her!The original mattress now lives in our spare bedroom, and I’m honestly relieved—it means our guests will actually have a great night’s sleep too. (Plus, I get to test it myself now and then. Spoiler alert: it’s still fantastic.)Unboxing was a breeze both times. The mattress comes rolled and vacuum-packed in a surprisingly small box. Just cut it open and poof!—it expands like it’s been waiting its whole life to be a bed. Minimal smell, fully fluffed up in about a day, and ready to go.The gel memory foam is cool and cozy—perfect for hot sleepers. It contours just enough to support without sinking, and my daughter says it’s been a game-changer for her sleep. No backaches, no overheating, just solid rest.For something that ships to your door and costs a fraction of the big-name brands, this mattress seriously delivers. If you’re shopping for a new place, a guest room, or just a sleep upgrade—you can’t go wrong here.Now I just need to resist the urge to buy a third one for myself

I agree that it is:High-quality, 3-layer foam with excellent materials and construction, medium-firm and comfortable, gives an excellent night’s sleep, is easy to assemble or custom-size (see below) and is an excellent value for the money!My review is especially important if you are choosing this mattress to fit onto a custom-sized RV bed!!PROBLEM: Replacing a custom RV mattress.Hubby and I needed to replace the worn-out Queen+ mattress in the master cabin of our RV. We chose this excellent KING-sized 5" thick mattress as a replacement, with necessary DIY alterations. Our current custom-fit RV mattress is much larger than a Queen but smaller than a King.SOLUTION: We ordered the KING 5" mattress, with a plan to cut it down to size in the same dimensions as our old mattress. The tools required to do this job are a tape measure, marker, long straight edge or yardstick, pair of large and sharp scissors, safety pins, needle and strong (upholstery or button-hole) thread and an electric knife that will be used to cut the 5" thick foam.Step 1: Measure the old mattress and record its length and width. If it is an odd shape, make a cardboard or paper template from the old mattress.Step 2: Open and air out the new mattress for a few days to allow for full expansion and removal of manufacturing odors. Continue airing out until the foam measures a full 5" in thickness. We accomplished this in our garage on top of two clean, side-by-side, folding tables covered with a clean sheet. We allowed 4 days for expansion and deodorization in cool, fall temperatures.Step 3: Open the Quilted cover neatly on the side(s) that requires cutting and fully remove it. Step 4: Now the mattress can be marked for size, by drawing a series of dots about 12" apart along the side to be cut. Use the tape measure and marker to place dots at several locations along the proposed cut-off edge(s). Step 5: Draw a long and straight cutting line to connect the dots with the aid of marker and straight edge. We needed to remove 12" from one side of the foam and 2" from the end. Mark one side at a time. If the mattress fits against a wall, plan to orient the mattress to place the cut edge alongside the wall.Step 6: Use the electric knife to cut a steady, straight and smooth line through the entire thickness of foam in the marked area. If possible, practice cutting a straight line in the piece of foam from the old foam mattress, pillow or other source.Step 7: After cutting, trial fit the mattress in place and make any needed adjustments. Replace the Quilted mattress cover (a two-person task) and use the safety pins to secure the folded cover over the areas where the foam has been removed.Step 8: Hand-stitch the quilted cover closed over the foam with the needle and strong upholstery thread.Step 9: Place the new mattress on the bed and check for fit. Too big?...start over and trim excess foam.SUMMARY:This excellent, medium firm 5" mattress will give you the best night's sleep ever. You'll wake up energetic and fully refreshed. The mattress is an excellent value at $110. We received an estimate of $680 from a fabric store on a 5" slab of foam - no cover or padding. We saved $570 by DIY with the purchase of this oversized mattress from Amazon!Enjoy!Highly Recommended.

Great deal. I purchased this for my RV that could take only a 5 inch mattress so I can fold it when pulling in the slide. The stock mattress was a joke. I replaced the stock with a 4" that was too thin, 6" would be too think to fold, so I took the risk in spite of folks saying the thickness is not accurate. In my case it was a perfect 5" within 2 minutes of opening the plastic cover.Given the shipping cost, packing, the wrapping cloth to protect the foam and a nice cover on top of that, the price is great. Not sure what anything really is worth anymore given the price fluctuation on a regular basis.The mattress is somewhat soft, I would have liked it to be more firm.

I was skeptical about a mattress in a box (how good could it really be?), but after two months of sleeping on this 5-inch gel memory foam wonder, I'm a total convert. The medium-firm feel is just right – not too squishy, not too hard – and it's made my old spring mattress feel like sleeping on a pile of textbooks by comparison.Why This Mattress Rocks:✔ CertiPUR-US & fiberglass-free – no weird smells or itchy particles (huge peace of mind)✔ Gel infusion actually works – no more waking up in a sweat puddle✔ 5" thickness is perfect for my platform bed – no sinking or sagging✔ Shockingly supportive for lower back pain (I can finally sleep through the night!)Small Reality Checks:

The mattress was not as thick as I expected but it did arrive rapidly and I appreciate that.

Absolutely love this bed!!!!! It's soft and extremely comfortable. We have slept so much better since purchasing this matress. Even when the dogs jump in the bed we don't know u til they are right up on us. Great quality for an awesome price

The corners never fluffed up to a normal size which wasn't too big of a problem for us since we were cutting it to a custom shape for a camper. The bed does lean more to the firm side then medium firm, but we like are beds that way and find it comfortable. It would be nice as a guest bed I imagine.

The set up was so easy!!! It did not have a bad smell. I previously ordered one for my mom. I loved it so much, I ordered one for myself.
