Review: Perfect Twin Mattress for Kids – Comfortable and Great Quality! - We bought this MLILY twin mattress for our child’s bed, and it has been a great choice. The mattress arrived well-packed and expanded quickly. It’s the perfect thickness for a kid’s bed or bunk bed, with just the right balance of comfort and support. The memory foam feels soft but still medium-firm, which helps with good sleep and posture. There was no strong odor, and the quality feels very solid for the price. Our child sleeps comfortably and wakes up happy every morning. Made in the USA and an desertcart’s Choice product—this mattress definitely met our expectations. Highly recommended for kids’ beds, daybeds, or guest rooms!
Review: Perfect 5-Inch Mattress for a Larger Double Bed - I was looking for a mattress for my double bed that I sometimes convert into a larger bed, and this 5-inch mattress has been exactly what I needed. It’s the perfect balance of comfort and support soft enough to sleep comfortably but still firm and sturdy enough that it doesn’t sag or feel flimsy. The memory foam adapts nicely to the body, giving good lumbar support even for adults, while still being ideal for everyday use. Setup was easy, it expanded quickly out of the box, and there was no strong odor at all. The size and thickness feel just right for a double tolarge bed setup, and overall it’s a well made, comfortable mattress that I’m really happy with.

## Features

- Unparalleled Quality Control – You can rest easy knowing your mattress is made with high standards and eco-conscious practices. Our global production includes U.S.-based and overseas factories for consistent quality. More than 90% of mattress orders are fulfilled by our U.S. factories. Wake up feeling refreshed every morning.
- Medium-Firm Feel - medium-firm is supportive for most body types and sleep positions. Too-soft mattresses don’t give proper support and can cause back problems in the long run. Too-hard mattresses don’t provide pressure point relief. The sweet point is our medium-firm (6-7 out of 10 on the firmness level scale) mattress strikes the right balance between comfort and support and promotes better sleep.
- Gel Infused - our foam is infused with a cooling gel that helps in dissipating heat, allowing you to sleep cool while retaining memory foam’s original body-conforming and pressure-relieving features.
- CertiPUR-US Certified - all foam used in our mattresses are made without ozone depleters and maintain CertiPUR-US Safety Standards of textile articles at all stages of production. It will have minimal off-gassing, or “new mattress” smell when brought into your home.
- Fiberglass-Free FR Inner Cover - the rib fabric, 92% Cotton, 8% Polyester, provides a safe, effective flame retardant layer around our mattresses, without the negative aspects of fiberglass and other fire-retardant chemicals. No skin irritation, no breathing problems, and no health risks for you and your family — so you can truly rest easy at night.
- Ready for Instant Enjoyment - compressed into one box that is easily shipped and maneuvered into the bedroom. Simply unbox, unroll and this mattress does the rest, expanding to its original shape within 2 hours.

### ⭐⭐⭐⭐⭐ Very Firm...
*by A***A on January 7, 2026*

Got this mattress for a kid’s bed and it’s been a great buy so far. It has a nice medium-firm feel that offers good support while still being comfortable to sleep on. The mattress expanded fully within a few hours and there was barely any odor after opening. For a 5-inch mattress, the quality is better than expected and it fits perfectly on a bunk or daybed. Pros: supportive yet comfortable, lightweight, easy to set up, made in the USA. Cons: on the thinner side, so may not be the best choice for adults wanting a plush feel.
