Awesome! Would buy again!
I absolutely love the FDW 12 Inch King Mattress! The medium-firm feel is perfect — supportive yet comfortable — and it contours beautifully to my body, relieving pressure points without feeling too soft. The gel memory foam helps keep the mattress cool, and I’ve been sleeping soundly through the night without overheating. Unboxing and setup were a breeze; it expanded fully within a few hours and feels just like the pictures online. The mattress cover is soft, breathable, and adds an extra layer of comfort. Overall, this mattress feels high-quality and luxurious for the price, and it has completely improved my sleep. I would highly recommend it to anyone looking for a comfortable, supportive, and affordable king-size mattress.

Comfy mattress for a twin bed!
SUCH A GOOD MATTRESS and doesn’t allow for jumping on the bed, which means NO NOISE! HUGE plus when having a rowdy 2-year-old that tries too. Haha. The mattress is very nice and cozy and even i wouldn’t mind sleeping on it. Firm yet soft, the memory foam is really nice! Fit perfectly on the frame with no issues and fits to your body nicely, it has definitely helped my sons sleeping since purchasing. it functions well and hopefully will last my kiddo quite some time. quality for the price is REALLY nice! highly suggest.

Amazing comfort and great sleep quality
I’m honestly impressed with this mattress. From the first night, I noticed a huge difference in how well I slept. It has the perfect balance of softness and support — firm enough to keep my back aligned, but still plush enough to feel cozy.I also love that it stays cool throughout the night. I used to wake up overheated with my old mattress, but not anymore. The quality feels premium, and it expanded fully within a few hours of unboxing.After a few weeks of sleeping on it, I can say I’m waking up with less back pain and feeling much more rested. For the price and comfort, this mattress is a fantastic buy. Highly recommended!

Solid Choice with Minor Trade‑Offs
I’ve been sleeping on the FDW 6‑Inch Queen Gel Memory Foam Mattress (Medium Firm, Bed‑in‑a‑Box) for a few weeks, and overall I’m quite pleased. Here’s how it stacks up:✅ What I LikedGood balance of support and comfort — The medium‑firm feel gives enough structure to keep my spine from sagging, while still offering some contouring to pressure points (especially around my hips and shoulders).Cooling effect — The gel memory foam does seem to help regulate temperature better than plain foam; I wake up less sweaty than on older mattresses I’ve tried.Easy delivery & setup — It compressed into a box and expanded reliably within a day or two. Very convenient to move and position.Removable / washable cover — The cover zips off and is easy to clean, which is great for keeping things fresh.⚠️ What Could Be BetterEdge support is weak — Sitting or lying near the edge feels less stable; it tends to compress more than I’d like.Thinness shows under heavier use — Since it’s only 6″, for heavier sleepers there’s a chance you’ll feel the base or frame underneath more quickly.Possible “break‑in” feel — It softened slightly after a few nights. Not a big deal, but the initial firmness was more noticeable than what I expected.Durability unknown long-term — It’s still early days, so I can’t fully assess how it will hold up over years of use.💤 VerdictThis mattress hits a nice price‑to‑performance sweet spot. If you’re looking for a budget memory foam option for a guest room, apartment, or lighter sleeper, it’s a strong pick. But if you’re heavier or rely heavily on edge support, you might want to consider a thicker or sturdier alternative.

Great Quality Mattress for My Daughter’s Bed!
I bought this FDW twin mattress for my daughter’s bed, and we both love it! It arrived quickly, rolled up in a compact box, and expanded to full size within a few hours. The mattress feels soft on top but still gives great support — a perfect medium-firm feel that’s super comfortable.My daughter sleeps through the night and says it feels “like a cloud.” The cooling gel really does help keep the bed from getting too warm, and the removable cover makes it easy to keep clean (a big win for a kid’s room!).Overall, this mattress is a great value — comfortable, breathable, and high quality for the price. I’d definitely buy another one!

Great quality mattress
Mattress was delivered quickly. It was easy to unwrap. It inflated to the full 8 inches in a day. No odor.. I ended up buying a second one… will be used for quests. It seems to be pretty firm.. and comfy.

Must buy!
I bought a kings size 14in and this mattress is by far the most comfortable ever! I didn’t think it was possible due to it coming in a box but I am so happy. I’m a nurse and don’t always get the best sleep but so far I’m sleeping through the night with no issues. I highly recommend if you’re looking for a firm but soft supportive mattress.

So Far, So Good
Definitely firm but still very comfortable. You will definitely sink down quite a bit if sitting upright for a while, but it returns pretty quick. Inflated very quick upon unboxing, dimensions fairly accurate to size ordered. So far only gripes I have about it is it seems to hold heat a lot? Not entirely sure because it is Summer but compared to my last mattress it gets a bit uncomfortable with my heat. That and the cover thing that comes with it, while it is a nice feature my cat’s claws constantly get stuck in it and the fibers seem to pull out easily. Lot of loose fiber nubs sticking out already in the month or so of use. The main reason I like this mattress though is it’s all foam, one of the only affordable ones I’ve seen where 95% of the thing isn’t crappy coil springs that wear out quickly. While most of it is “support foam,” it’s still nice being so thick with actual cushion. I would recommend specifically the 10″ size as it seems the rate of actual memory foam they offer per size doesn’t increase much, less value in it. A bit weird of a policy since you’d be paying more.. would expect some more quality foam. Suppose it’s due to width increasing making increased memory foam being more spread out. Overall pretty good bed, would recommend.

This item was delivered quickly which was great.The mattress is great! Soft yet firm.I am a 6’1 stomach and side sleeper and with my previous mattress was experiencing lower back pains upon sleeping and awakening.Since sleeping on this mattress I have not experienced any pains and upon awakening I find myself thinking “just 5 minutes more”.I had my doubts and concerns but was rewarded with a great, pain free, sleep.I did not give 5 star rating because of the time it takes to fully be “poofed”.Patients was rewarded.I recommend and normally don’t waste my time with writing reviews.

At 210lbs I’m very happy with how firm this 6″ high density foam mattress is. We slept on it for over two weeks and it’s a perfect replacement for our camper. I have a breathable layer under it but raised the mattress for better circulation after using it to make sure.

We ordered the 5” mattress but received the 3” mattress but besides that , it’s a good product. Very comfortable. Just wish we had the right thickness since we pay more for the 5”

Do Not Waste Money ! Very poor quality mattress Buy something else instead !!!I am writing this review to warn anyone considering an FDW mattress: DO NOT BUY IT! This has been, without a doubt, the single worst purchase I’ve made since while.I had twin mattress from ZINUS before and had no issues even after using for two years. But after marriage i needed something larger so I bough Queen mattress from FDW. What a nightmare started getting soft withing three months. By the time you notice things warranty phase is over. Step by step it lost its density so much so that now if you sit on it you can literally feel ground also firmness varies on different areas. All in all is absolutely ”NO, DON’T BUY IT UNLESS YOU WANT BACK PAIN WHICH YOU NEVER HAD IN PAST”
