    • Comfy mattress for a twin bed!
Color: White Size: Twin Style: 8 IN
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. ... show more

    • Great Quality Mattress for My Daughter’s Bed!
Color: White Size: Twin Style: 6 IN
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! ... show more

    • Solid Choice with Minor Trade‑Offs
Color: White Size: Queen Style: 6 IN
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. ... show more

    • Comfortable and supportive mattress at a great price
Color: White Size: Full Style: 8 IN
This FDW 8-inch memory foam mattress has been a pleasant surprise. It arrived well-packed in a box, expanded quickly, and had little to no odor. The medium-firm feel is just right—soft enough for comfort but firm enough to provide good support. The cooling gel foam really does help keep it from getting too warm at night, and the removable cover is a nice bonus for easy cleaning. For the price, it’s a fantastic value and feels much more expensive than it is. Perfect for guest rooms, kids, or even everyday use if you like a medium-firm bed. ... show more

Review Image by Es súper bueno Es súper bueno
I am extremely happy with this mattress! The 5-inch gel memory foam provides the perfect balance of softness and support. It feels medium-firm, which is exactly what I needed for a comfortable night’s sleep. The cooling effect really works—I no longer wake up feeling hot, and the pressure relief makes a huge difference for my back and shoulders. The mattress arrived quickly, well-packaged, and expanded to its full shape within a few hours. The quality is impressive, and I love that it’s CertiPUR-US certified, giving me peace of mind about safety and durability. For the price, you honestly can’t beat it. It’s lightweight, easy to set up, and fits perfectly on my bed frame. If you’re looking for a comfortable, affordable, and reliable mattress, I highly recommend this one! ... show more
