Perfect for bunk beds

We really like this mattress! It’s perfect for a top bunk bed. It didn’t take too long to inflate, 24 hours. We like that it comes with two mattress covers! It’s perfect for a kid. Our son said it was the best sleep he’s had!

Great transition mattress for toddlers

I bought this as a transition bed for my toddler. I really love that the top of the mattress is removable via zipper so it can be washed. It's also waterproof. It came with an extra top cover, which is super convenient. The mattress is medium firm and comfortable. It passed the jumping on the mattress test by my toddler, lol.

Good Temporary Mattress

This comes with an extra top cover so that you can wash it easily. I don't know that this would be a good mattress by itself. I think it is a good mattress for visitors or as a mattress topper. It's comfortable and solid without being too hard.

Get one!

Got this for my stepson and am really thinking I need to get one for my son. He loves it, they both do! Apparently they’re good to jump on too! I like that the cover comes on it, makes it much more convenient!

Twin matress

This matress is very nice. It fluffed up as expected. It did have an odor on day one however that went away fairly quickly. I love how it has an extra cover and that they can be removed and washed. The directions are pretty cute too!

Great for Parents Who Cosleep or Kids

If you’ve experienced any late night, sheet changes because you had an accident or is just sick, this is a great mattress for you. With the removable waterproof cover that easily zips on and off the top of the mattress, you can strip your bed quickly when in need, zip on the extra cover that is provided with the mattress, and get back to sleep. This could be a game changer for a breast-feeding mom, or a kid who still wets the bed. You don’t even need to put sheets back on the bed because the extra cover is soft to the touch and could be laid on directly.

Perfect fit under our trundle bed!

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!

Firm, comfortable & great zipper cover

Mattress was shipped quickly and easily. Arrived packaged nicely and undamaged. We quickly unwrapped to allow it time to expand and avoid any unwanted odors, as advised. The 6” mattress is just thick enough for my son, and is perfect. You can smell the hint of green tea that is infused inside. The mattress is firm but comfortable. We really like the zipper cover with moisture protection and an extra for easy cleaning days.

Great value mattress!!

Nice mattress for our sons room! It came in a box that wasn't too heavy. Nicely packaged and easy to get upstairs, unlike other mattresses with bulky box springs. You need to let it lay out to rise. I did for a couple of days. So far, so good! It's comfortable and my son loves it. It replaced his old twin mattress and we have it on a raised bedframe and it works great!

Does not fully expand

Mattress arrived Friday morning and we brought it inside and unwrapped within 2 hours of arrival. It is now the following Thursday and the mattress is still not inflated. (It is supposed to inflate in 24-72 hours). The corners are practically flat and the WIDEST part of the middle is only about 4.75 inches, most of it is 4 inches or less. (The twin is supposed to be 6in). Looking at the back, it doesn't even look like the white part of the cover is the right size? It seems like the white should be as big as the mattress to allow for expansion at the corners. I can't get the zipper out of the cover on the back so I cannot open it up to see if it will expand further without the cover on. The zipper on top is just for the top layer. Will be trying to schedule a return, very disappointed.

reply from Zinus

Our mattresses usually fully decompress within 48–72 hours, though in some cases it may take up to a week. You can sleep on the mattress during this time—this won’t slow the process and may actually help. To speed decompression, you can jump on it, roll across it, massage the corners, or gently walk on it. If your mattress has not fully decompressed after one week, please contact us at support.zinus.com for assistance.
