Ratings & Reviews+

Mainstays 6-inch White Innerspring Twin Coil Mattress is rated 4.2 out of 5 by 100.
Rated 5 out of 5 by from Very pleased with this mattress. Comfortable and light weighted which makes it easy to lift when making top bunk bed. Because of the mattress height the guard rail has sufficient space to ensure safety from falling.

Rated 5 out of 5 by from Would buy again! The mattress is comfy but I would not buy it for a teen or adult, but great for my 8 & 9 year old granddaughters!

Rated 5 out of 5 by from Great mattress for kids!! I bought these mattresses for a new bunk bed I ordered for my children. I ordered this one specifically because of the 6" thickness, which was what the bunkbed required. This is a great mattress for children. I don't imagine it would be very comfortable for an adult to sleep on every night, but for the kids, it's perfect, and for the price, you can't ask for much better.

Rated 4 out of 5 by from Good Product It was so interesting how the mattress expanded when the package was opened. This mattress wouldn't have enough support for me but for our boys they're perfect. Good mattress for a very reasonable price.

Rated 5 out of 5 by from Perfect! I bought this for the top bunk of my sons bed. It came in a tiny box that you would never think a mattress would fit in but once opened, and the vacuum seal broken, the mattress opened up to its full size! It's light which makes changing the sheets on the top bunk easy and the price is right! I'm very happy with my purchase.

Rated 5 out of 5 by from great value! We were looking for the mattress for my 5 years old child in different stores. When we bought this mattress I was doubt about the quality for this price. It was not nothing on display in the store and when we opened at home I was suprized how good it is. I am glad that we didn't buy foam mattress in IKEA for $149 as this Wallmart mattress has much better support and great price.
