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.

Very nice mattress. It made it easy to get having in packed and shrunk. It took a day or two to fluff up to full size. I have it on a loft bed and it fit nicely. Just make sure you line it up and I opened the wrapping after I put it on the bed, so that made it easier to work with. It was a little heavy, but that is expected. It was a good price for what we needed.

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!

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.

very firm and comfortable despite it only being 8 inches thin. you can feel the memory foam as well. been able to sleep peacefully where i normally have an issue with it. don't know what else you can say about a mattress doing what it's intended for pretty darn well.

Purchased this mattress last year to replace the thin, worthless mattress in our travel trailer. So comfortable! It was easy to unpackage and install. Just the right amount of firmness for my aging back. Very pleased with the price and its functionality. Love the thickness!

I have bought several mattresses through the years, for our cabin and home, this is truly the best one. There is little to no odor, and that dissipates within a few days, not weeks as with other models. I did wash the cover upon arrival, which did help. The gel memory foam top layer adds extra comfort to the mattress. This makes a great spare mattress for the home, cabin or RV. Great Buy.

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 Liked Good 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 Better Edge 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. 💤 Verdict This 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.
