  • Yes!!
Color: White Size: Twin Style: 8 IN
I am genuinely shocked by the quality of this 8-inch thick twin memory foam mattress, especially given the price. I went into this purchase with low expectations, assuming it would be just a temporary solution, but it has completely exceeded them. The mattress expanded to its full size quickly and has a perfect medium-firm feel. It provides excellent support and conforms to my body, relieving pressure points and making for a comfortable and restful night's sleep. It's an absolute steal for anyone on a budget who doesn't want to compromise on comfort. This mattress is a prime example of getting far more than you pay for. ... show more

  • Good mattress
Color: White Size: Twin Style: 5 IN
Pretty comfy, you might want thicker than 6” as an adult, but I could see myself sleeping okay on the 5” if it’s all I had. However, it’s perfect for my 2 year old. It seems true to size and puffed up after a couple of hours. It has a little odd smell, but it went away quickly. I’d say this is a great product for the price. ... show more

  • Full and firm
Color: White Size: Twin Style: 8 IN
These were super thin in their package and made me a little nervous. However within minutes of unwrapping they expanded and are super comfortable! Very thick, soft to touch but firm enough to offer support. Great value for price.

  • Very firm
Color: White Size: Queen Style: 10 IN
Got the 10" for a murphy bed. We like a firm mattress, but this thing is HARD firm! If that's what you're looking for, it's great. If not, move along. Seems well made, no weird scent upon opening (maybe a light scent but dissipated quickly!). 83yo MIL slept on it and said it was comfortable. She likes it hard. ... show more

  • Cool and Comfortable Mattress
Color: White Size: Twin Style: 5 IN
Matress was delivered on-time in an easy to open box. Matress is soft enough with lots of support and keeps cool. Product fits perfectly on a trundle bed for easy storage. Mattress makes no noise when moving around during the night.

  • Great and affordable
Color: White Size: Queen Style: 10 IN
Super comfortable. Expanded very quickly and has no odor. Definitely on the softer side, but it's just what I was looking for. It was delivered 5 days sooner than expected so that was great, too!

  • Six-Inch Mattress: Perfect for the Top Bunk!
Color: White Size: Full Style: 6 IN
This six-inch mattress has proven to be an excellent purchase, particularly for its intended use on a top bunk bed, earning a solid four stars from me! Finding the right mattress thickness for a top bunk can be tricky, as you want to maximize headroom and ensure the safety rail remains effective. This mattress nails it. It offers a surprising amount of comfort and support despite its slim profile. My child sleeps soundly on it, and I feel confident that they are getting adequate rest. The thinner design is ideal, keeping the mattress well below the top of the safety rail, which is a huge plus for peace of mind. Installation was a breeze due to its lighter weight and manageable size. The only reason it's not a full five stars is that, while great for a bunk bed, it might not be the ultimate in plush luxury for an adult or main bed. For a child on a top bunk, however, it's virtually perfect. It's durable, functional, and provides exactly what's needed without being overly bulky. If you're in the market for a mattress that perfectly fits a top bunk and offers a great balance of comfort and safety, this six-inch option is highly recommended! ... show more
