Very happy!

Have never purchased a mattress online before but I know many people that have! I’ve heard good and bad stories. So after a lot of review readings I went with this one! Purchased for my special needs daughter and it’s perfect! Love that it has waterproof protection and an extra one. love that it unzips, makes for a quick bed change!! It’s everything I ever wanted out of a mattress for her. You can’t put a price on that! And the price tag is VERY budget friendly. It unboxed perfectly, unfolded perfectly!

Great foam mattress!

This product came rolled up and vacuum sealed which made it easy to handle and maneuver. The unboxing was quite simple and straight forward. After leaving it come to for and breath I was surprised at the firmness of the mattress which I liked. The mattress did not have an overpowering odor which is also difficult to do when working with foam. The mattress came with a second top cover that simply zips on and off for fast changes and easy washing. The cover is soft and comfortable. This mattress fits well with our current bed so we did not have to buy a new frame.

Great for kids bed

This bed is great for kids. Its very comfortable and firm enough to offer support for growing kids. The water proof covers are great too. Comes with two, so if your kid has an accident there's another to put on while the soiled one is in the washer. Highly recommended for kids. Didn't have the problem with expanding with the full mattress like some of the reviews for the twin had

Zinus Night Therapy 8 inch mattress

We love this mattress! I initially thought it would be a great guest room mattress but my daughter wanted it instead. It was quick to inflate (about 24-30 hours), came with 2 waterproof mattress protectors and the perfect plushness. She has slept on it for about a week now and loves it. I slept on it the first night and will probably be ordering a king size soon.

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.

We love it!

We purchased this for our 2 year old and we absolutely love it so far ! I’m very thankful it comes with TWO zippered covers for future accidents 🙌🏻 I was a little discouraged when I opened it and saw that they had to be air dried, but they shocked me and were completely dried by morning!!!

Perfect for my Toddler!

I am so happy with this purchase. It is perfect for a toddler or young child! I LOVE LOVE LOVE the zipped on waterproof liner… and the fact that there are 2 is even better! Makes it so easy to change out if/when an accident happens. Also shipped way faster than anticipated.

If you want a good nights sleep this is great!!

Got this bed for my son who was having trouble getting comfortable sleeping at night. So far he has been having great nights sleeping. The mattress is super comfy and i love that it has a water proof cover already on it. With littles that is a need!! Definitely will be getting my daughter one too.

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.<br /><br />To speed decompression, you can jump on it, roll across it, massage the corners, or gently walk on it.<br /><br />If your mattress has not fully decompressed after one week, please contact us at support.zinus.com for assistance.

Does not expand to 6 inches!

This "mattress" never expanded more than 4 inches. We unwrapped it and right away it expanded to about 4 inches, now it's been about 2 weeks and still 4 inches. We have been trying to return it, but they are giving us a hassle. Can't just roll it up and put it back in the box to send back.
