  • Comfortable and Great Quality for the Price
Color: White Size: Queen Style: 10 IN
This is a good-quality mattress, especially for the price. Mattresses can be really expensive, but this one is surprisingly comfortable and feels well-made. It’s not too firm and has a nice soft feel, which makes it easy for me to fall asleep and stay asleep. Honestly, you could buy this mattress and no one would ever guess it’s from Amazon. I’m very happy with this purchase and think it’s a great option if you’re looking for comfort without spending a ton. ... show more

  • Perfect Compact Mattress for Everyday Comfort!
Color: White Size: Twin Style: 5 IN
I bought this FDW 5 inch twin mattress to use in a guest room and I’m really happy with it. The medium-firm feel is supportive without being too hard, and the gel memory foam layer conforms nicely to your body—it’s been comfortable for both back and side sleeping. Nellis Auction Set-up was super easy: it arrived compressed in a box, and within a couple of days it expanded fully and was ready to sleep on. The removable cover is a big plus too—I love that it’s washable and easy to keep clean. Nellis Auction What really sold me was the CertiPUR-US certification, which gives peace of mind that the foam is made without harmful chemicals. Nellis Auction Whether it’s for a kid’s room, guest space, or even a small apartment, this mattress delivers great support and comfort at a great price. Highly recommend! Nellis Auction ... show more

  • ⭐⭐⭐⭐⭐ Comfortable and supportive for everyday use
Color: White Size: Queen Style: 5 IN
I purchased the FDW 5-inch queen mattress (medium firmness) for a spare bedroom, and it’s been a great choice. The mattress arrived well packaged and expanded properly after opening. It feels comfortable and supportive, especially considering the thickness. The medium firmness provides good support without feeling too hard, and it works well for back and side sleeping. After several nights of use, it’s held its shape nicely and hasn’t sunk in. The mattress doesn’t have a strong odor, which I appreciated, and it was ready to use fairly quickly. For the price, the quality is better than I expected. Overall, this mattress does exactly what it’s supposed to do. It’s comfortable, supportive, and a great value. I would definitely recommend it for guest rooms, apartments, or anyone looking for an affordable mattress option. ... show more

  • Good option for a bunk bed
Color: White Size: Twin Style: 5 IN
I should've done the 6 inch mattress to get a 5 inch because the 5 inch is only 4 inches. No oder, expanded quickly just not to the advertised size, feels soft and comfy. Had it a month and no complaints yet.

  • Great Buy!
Color: White Size: Twin XL Style: 10 IN
This is our second mattress purchase and we love it! We originally bought the Twin XL a few months ago, but we went ahead and got a second to make a king sized bed in our guest room. They are great quality, comfortable, not too soft but not too hard. I love the thickness the 10in adds! Delivery was an ease and set up is even easier. You can't beat the price, either. I would recommend this product to anyone! ... show more

  • Comfortable and soft
Color: White Size: Twin Style: 8 IN
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. ... show more

  • Good purchase!
Color: White Size: Twin Style: 6 IN
I bought this mattress about 6 months ago. After reading so many different reviews of other mattresses I made my decision and bought this one. I'm glad I did! The quality is good, firm and very comfortable. I just bought a second one for my other bed. I'll be back for an update.
