Even though the mattress is shipped very compressed. It expands and is just as firm as any other mattress of similar type. I am very pleased with my purchase.

The mattress came rolled up not in a box we were very shocked to see that since it shows in a box. It was pretty heavy and we had to make sure it unwrapped slowly so we didn’t get hurt. It’s pretty nice for a guest room bed. We like it.

We bought this mattress for our niece and she loves it. It has enough support so if an adult had to sleep on it it would still work. Good value for the money.

This was so easy to take out box and setup my 11 year old was able to do it. I like the firmness of the mattress. It seems solid I will review again when I sleep on it.

The bed came quickly (earlier than expected) and that was great, but it didn't give as much support/firmness as expected. We ended up buying a topper for it, so that helped.

Sams Club description for the 8" hybrid twin mattress clearly provides that the mattress included a frame. Pictures show a frame.The mattress does NOT include a frame despite the description. It is only a mattress. Sam's acknowledged that there should be a frame and said it would send one. It only sent another mattress. Now, I have two mattresses and no frame. No offer to help, no offer to come pick up extra, no help with frame, told to call Zinus. And then, Daniela just hung up the chat and said she was releasing the chat to help the next member. Did not arrange a pick up, refund, or anything. Gave no further directions. Very abrupt. So now, will have to drive a mattress hours to return. Bad business.

This bed is extremely firm. In the description it says it comes with a base or box spring; it does not. I called Sam's and was told I could replace the order and it would come with a box spring and they would pick up the mattress I recieved. I did not get a box spring, just another mattress. I can't imagine what they paid to have it picked up by a third party. They are wasting money and have an inaccurate description. I love Sams, but I'm unsure if I can trust the item description online.

Very firm mattress

Arrived much faster than expected. Packing technology is amazing. Drawback is the wait for the mattress to expand. Initially I felt the mattress was too soft and not so firm but over a period of 2-3 weeks the firmness increased. Will be keeping it. The 13 inch would also have been a good choice but the more the height, more will be weight to manage every time I move.

The Mattress is great, it is a little stiffer than I imagined it to be from what I read about it, but I love it. This one was for my son but the next one will be for me and I will put down the extra dollars for the 13" I-coil. For my son I'm looking for a mattress topper but the value was great and the quality of the product is awesome. This is how mattress shopping should be.
