I got this mattress with the hopes that it would fit in the trundle bed area. It fits perfectly!!!! I also love the zip off waterproof cover! One less thing that I need to purchase for the bed. It comes with 2 of them so that if one is dirty, you have a spare!

Everyone is happy with this mattress! It is definitely waterproof, and comes with an extra topper waterproof cover so while one is being washed, you have a backup to put on and get your child back to sleep quickly. Medium firmness had me worried because I know firm is preferred for developing bodies, but we decided to give it a try thanks to the Sam's return policy. This twin 6" foam mattress is firm enough for a toddler. Would not recommend for adults as a nightly sleeper as the twin is intended to be a bunk bed mattress at only 6" thickness and meant for children who are going through the potty training phase of life. After rolling mattress out, allow 48 hours to breathe and fluff up before judging firmness. We plan to replace when our now 3 year old toddler turns about 10. Thank you Zinus and Sam's for offering such a quality mattress geared towards this very specific window in our toddlers life at an affordable price!

It unrolled from the box very easily. It came with a second cover which is nice to have an extra one. It expanded well over a few days. The bed is pretty comfortable and one of my kids said it was the best night sleep they have gotten in a while.

Nice firm mistress for little ones! I love that the washable cover zips off and is so easy to change and it comes with TWO covers!

It arrived in good shape and early. It decompressed in the stated time and it is quite comfortable as well. Happy with my purchase.

Perfect for those that prefer a firm mattress. Plush yet firm

it is good
