Had we not read the reviews prior to purchasing a mattress, we would have never chosen this one. It comes vacuum packed. Be sure you have it setting where you want it before removing the vacuum pack. It becomes its true size within seconds. Ours was ready to sleep on within the hour. We also ordered the 4" box spring that requires some assembly to go with it. Perfect height for a young child! There was no odor at all?? We love it!

Alright folks, so I have the Cal King Zinus Night Therapy Green Tea memory foam mattress. This is the first memory foam mattress I have ever had and have been sleeping on it for 2 weeks now. This mattress was easy to set up came in a box roughly 4 ft tall and weighing close to 100 pounds. My wife and I unrolled it right onto our box springs and removed the plastic. Within seconds the mattress came alive forming into its full form within 2 min. Now the instructions state that it takes from 24 to 72 hours to fully form (we only waited about 14 hours and it was fine). A slight odor but nothing that wasn't what was stated from the instructions. Now the important part, sleep. This memory foam mattress seems really firm. My 6 year old was pretty upset he couldnt get the spring from bouncing on it like the old mattress haha. So I am a belly sleeper and so is my wife. I slept great! My wife even enjoys sleeping on her back now which she said shes never been able to do. I am giving it a 4 star just because it is, in my opinion, a more firm mattress and thats not really how I read or expected it would be. But other then that after 112 hours of sleep I do wake up refreshed and ready for my day. Though in the last couple nights I did wake up with a little neck pain, but that could be from the way I was positioned. I would recommend this product if you are looking for a cheaper option for a mattress at the Cal King price of 450, Its very economy friendly.

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.

Finally able to get rid of our old Pillow top and so glad we could- this mattress is firm so we don’t sink in but also comfortable enough that I don’t feel pain especially at my hips and shoulders. It is a great quality that looks like it will hold up well especially as my husband and I are toss and turners. Also love the green tea infusion upon opening like other times we opened memory foam mattresses - we did not feel assaulted by smell after opening to air out - it was very pleasant and not strong at all. Would buy this mattress for our other rooms hands down

We bought 5 of these for a vacation rental, one 12 inch and four 10 inch. We’d have bought five 12 inch but only one was in stock. Timeliness and convenience of delivery and set up were great. We slept on a 10 inch for a couple of weeks while there working on the property and found it very comfortable. The quality of materials and construction look good. I expect we will get a number of years of good service from these mattresses. We do love our $4,000 Intellibed mattress at home but these inexpensive mattresses from Sams Club offer a very similar nights rest.

We had purchased a memory foam mattress from Sam's club in the past and loved it. Now it was time to purchase another and I happened to get a text from Sam's Club alerting me to Black Friday deals. I was able to not only get the mattress we wanted but it was half price with free shipping! It was so easy to unpack and set up. it was fully ready to use within 48 hours. Super comfortable and great sleep.

I’ll admit I was skeptical at first but I really like this mattress. It comes rolled up tightly wrapped in plastic in a box that seems too small to fit a mattress so I had my doubts on the quality. But I was very wrong! This bed is so comfortable! Definitely more comfortable than the mattress it is replacing. I let it air out for a day or so. The smell isn’t bad at first but definitely is noticeable after a few hours. Don’t worry, it goes away by the next day. It’s fun watching the mattress expand. It happens pretty quickly once it comes out of the wrapping, probably 60 percent filled, then continues to expand slowly. The green tea is a nice touch, but I don’t know how long that will last. I went with the 12 inch mattress because I like the extra height and it was perfect for me. The bed is so comfortable. I had the best sleep I’ve had in a long time and it’s been a couple weeks now and I have yet to wake up in the middle of the night, my sleep has been so restful. I was worried there would be a long breaking in period, but since it is memory foam it just conformed to me immediately. It’s the perfect mix of firm but soft where I need it to be like it's cuddling me. I highly recommend giving this mattress a try, it’s been a great experience for me.

This arrived in smaller packaging than I was expecting but expanded to full once opened. I wasn't sure how I would like the memory foam after using a pillow top for a few years but I was amazed at how well I slept. I use a water pillow which causes indents on my pillow top but I didn't have any of that on this mattress. Very comfortable and sturdy.

This 12 inch memory foam mattress is SUPER comfortable! It came in a relatively small box (for a full sized mattress) but when we opened it, within an hour or so it had expanded quite nicely. It took overnight for it to go to full height and be sleep ready. I use this for my 11 year old and it is perfect! It has a decent firmness to it, but also a nice softness (it might be a little too much for some people). My only concern, and this is a very small one, is that the edges are not that sturdy (as you can see in the pictures). This is not a bed for sitting on the edge, but how many people really care about that?

Heated over night but an over fill matress pads help, it's really good no more back pain, in the morning more energy to just wake up in go to work I used to sit down for the back pain relax stretch now get up in go.. I recommend this matress it's really good and a good price too.
