This mattress is not even on all sides, I get 9" on one side, 10" on another, almost 11' on another, but never 12" which was advertised. It makes you feel like you're going to fall out of bed. I normally sleep on the left side of the bed, but since getting this mattress, I have to try and stay in the middle, so I don't roll off. I spoke to customer service, they gave me a percentage off, but this bed is not worth it. I wish I would've just asked for my money back, I'm very unhappy with this mattress!!! Thank you Adam for your help, but this mattress is horrible, in my opinion. I would not recommend it to anyone☹☹‼️

This memory foam mattress is relatively firm but still has give to your body weight. I thought it wasn't firm enough but my wife thought it wasn't soft enough. We were afraid that it was going to smell of green tea. There isn't a noticeable smell. When sleeping with a partner you don't notice their movements as much as I traditionally have on a spring mattress. Not sure if it passes the "wine glass test" though. The mattress does not get hot at night although it is not cold either. Was this the best nights sleep that I ever had on a mattress? No. Was I comfortable? Yes. If I were at a hotel I'd be fine with a mattress like this. I'm just not sure if its right for me every night. I would recommend this mattress to most people unless you are particularly picky on how your mattress feels and sleeps on. Mattress comes boxed rolled up and is recommended to open within 72 hours. It takes just over a day for it to fully expand to full size.

This Zinus 12 inch mattress topper is a great very comfortable, soft but firm at the same time. We put it in our den for extra bed for our guess specially last Thanksgiving week and this coming holiday season.I can’t believe that this just a topper. It could really be a real mattress. Same me money to tell you the truth. Highly recommend product

This is the 3rd Night Therapy my husband and I have purchased now. Best sleep ever. It is soft but firm support. Both of us used to wake with back aches on the old mattress, never again since the night therapy ones. Can't stand the soft mattresses that you sink into and wake with a hurting back. This is soft as you climb in bed, but comfortably supports the body firmly but not hard. I reccomend these mattresses, especially if you have back aches.

I really have to say I truly love the smartbase that came with this mattress it is so lightweight that I by myself was able to unpack it, put it together and take it upstairs all by myself, and this was the king size! The smart bass has these clips that click when the legs lock out and in order to get them to go back down you have to press the button on it so you know it's locked when you're using it. I have had bases similar to this before that were so heavy, and even though the king comes in two pieces, I had to have help moving it. It also breaks down and stores super flat which is so nice if you have to move furniture to paint or you have to move. It does not take up a lot of room stored. I was surprised at how small the box was that it came in when I put it together. The height of the base is 14 inches. The green tea mattress I have to say did not have a lot of offgassing like some of the other mattresses that are similar that I have purchased before from other brands. It comes with directions that tell you it needs to be opened as soon as you get it and let it rest for about 72 hours which I did, it did have a slight odor but that's to be expected for anything that's been wrapped in plastic and that is a memory foam mattress but it was definitely not bad. I could be in the room with it and be in the house without it bothering me. The smell that it did have disputed so fast I was actually really impressed with that. After getting everything set up and sleeping on it for about two weeks I noticed that my back did not hurt as much as it normally does. The mattress is probably more of a medium stiffness not overly soft and not as hard as a medium firm mattress like my previous one was. it does hug you a little bit when you are sleeping so you don't feel a lot of movement from anybody else it's in the bed. The one thing though I did notice that after having it set up for a long time and sleeping on it is that the 12 inch mattress actually measures out to be more of around 11 inches good thing to know for purchasing sheets so you do have a little bit more options in sheets than a normal 12 inch mattress.

I really like the firmness and comfort of this mattress. We kept the box spring from our old regular mattress set and placed this on top of it. The con is that it moves when you touch it. I bought some wide double stick tape to place on the top of the box spring to hold the mattress in place. Have not had the chance to put it on yet so not sure if it works but keep this in mind when buying.

This mattress is very comfortable. It is firm but the top layer is soft, so very comfortable. I have it in the guest room where it won't be used every night so I can't speak to how long it will last. For the price, I am very happy. It arrived quickly.

This bed is amazing. I’ve slept very good on it so far this past month of having it. My wife had pretty bad back pains that have since stopped largely due to the bed. The bed is very firm so keep that in mind if you don’t like firm this is probably a little more than medium firm but less than hard firm. It is all around amazing. It didn’t take long at all for it to inflate. Just don’t wait until you’re about to go to bed to take it out. You’ll need at least 2 hours for it to get to its full size even though the box says 48 hours. It might be different for others though. I definitely recommend this bed if you like firm gel like mattresses.

I bought the green tea queen in September and love the firmness. My back feels much better in the morning. We have decided to replace all of mattress in the house with Zinus mattresses and the box springs. Box springs are top notch. My only complaint is the mattress tends to slide on box spring. Two-side Velcro solved the problem.

This is a great product. It was easy to open and setup. I was a little disappointed that I didn't receive the Bifold frame though. The mattress had a firmness yet softness that at no point did I feel uncomfortable. I actually had some of the best nights of sleep I've ever had. I wake up feeling refreshed with no soreness in my joints.
