Excellent Mattress for the Price

Great mattress for the price. I would say it's on the firmer side but still very comfortable. The last memory foam queen I bought from Sam's you kind of sink into it and had some effort rolling over but that does not happen here. And the fact it comes shipped to your door in a box is unbelievable. It was fully inflated out of the box in probably under 48 hours.

Never reformed. Terrible customer service

Delivery was quick. We immediately opened the mattress as it states not to leave it in the packaging over 72hrs. After 24hrs there still was a valley in the middle of the mattress. The instructions stated that it could take up to 48hrs to reform. After 48hrs there still was a valley. I contacted Zinus. Zinus told me it could take up to 7 days. Then Zinus told me that any other concerns need to be conveyed to Sam’s Club. After 7 days there still was a bit of a valley but we decided to give it a try. Some of the reviews did state that sleeping on the mattress and working it a bit did help it reform. 17days later I checked and the valley is still there. This seems like it could be easily avoided if the mattress was just rolled up and NOT fol...

    Great mattress

    Bought this based on a prior purchase for a twin sized bed. This one is deeper and very comfortable. It’s on an adjustable frame and works well. I sleep really good with it in the 0 gravity position. It’s also very good for a side sleeper in the flat position.

    Very pleasantly surprised!

    I had been shopping for a new mattress for a while, watching sales and reading reviews, when I came across this relative unknown ZINUS Nigh Therapy mattress at Sam's website. While there were only 50 some reviews, to my surprise there were none below 4 stars, so I decided to give it a try as it was also on sale for $100 off with free delivery. The box arrived a few days later, and I was surprised at how heavy it was. It weighs about the same as a regular mattress but it's all condensed into a box that is about the size of 2 King pillows atop each other. Anyway, I carefully opened it up and set it on my old box spring to allow it to unroll and "inflate". By that night, it was exactly as it looked online, just under 12 inches, but not by...

    Ultra Cooling Green Tea memory foam

    10yrs ago we got the traditional greentea. Loved it. Last week we got the Ultra Cooling gel. True to advertising. Awesome for this 57 yr old menopause lady. Comfort A+ as well. Highly recommend

    Went back to Zinus!

    Hubby now sleeps cool and my joints are relieved. Owned an original Zinus many years ago and put them in the rooms of the small motel we owned. Ours got ruined in a hurricane and we went with another brand because back then we could get it faster. When that one wore out, tried a hybrid but was not for us. Went back to Zinus!

    A perfect balance of firmness!

    I’m loving the mattress. I had a Zinus mattress and moved into a new space. I tried another mattress and it simply does not compare to the Zinus. I’ve experienced back pain over the past few months and with the Zinus mattress I’m already getting a better nights rest within a weeks receipt! It’s just the right amount of firmness that allows support, but gives that soft, comforting feel. A perfect balance for my liking!

    Excellent mattress!!!

    “A few days ago my mattress arrived. I still have two more days to use it (72 hours). I’m really excited to try it out — it looks great, definitely a good purchase!”

    Happy with new mattress

    Very happy with my new mattress. Comfortable top memory foam layer, with good firm foam support below. Mild off-gassing smell for a few days, but not that bad. Seems to be resolved now. Overall, quite pleased

    I am pleased

    My shoulders no longer hurt in the morning. Much less tossing and turning and my arms are not falling asleep. I slept on a Zimus mattress at an airbnb and ordered while I was still there. That one was firm on the edges. This one is super mushy and not good for sitting on the edge of to put on shoes. But I don't hurt so I am okay with sitting in a chair for shoes.

    No edge support

    The middle of the mattress is okay but the edge lacks so much support that I fell off the bed the first night. I’m only on night 2 so hoping the edge firms up quite a bit. Otherwise, I will probably go through the hassle of returning this.

    Not happy!

    This morning my son set up my beautiful new fullsize bed frame and unpackaged the new mattress to allow several hours for it to plump up before I would make it up with my new bedding. I have just now gone to bed and I am afraid of sliding off the edge onto the floor! The mattress is so soft and goes as flat as a pancake when one lies down! Trying to move towards the center of the bed, leaves one struggling to roll 'uphill' to the high point in the middle. I cannot see this working for me. I am willing to give it a few nights, but honestly this is a big disappointment. I love your product but this one is not good.

    Okay

    I bought this mattress to replace a Zinus mattress I've been sleeping on for 10 years. I'm sad to find there's no structure in the edges any more. Compared to the previous mattress, there's a significant percentage of lost usability because the edges collapse down

    Too soft

    The mattress is good quality and nice material. Unfortunately it is just too soft for us. If you like to be cradled by your bed (which to lay on is lovely but a hard time sleeping) you will love this mattress. I wish it worked out for us.

    Quality diminished

    This is our second Zinus mattress. We bought the same exact one three years ago and were very happy with it. Just bought another for our second home and are disappointed in what feels like a decrease in quality. The edges of the mattress sink so you even feel like you’re going to roll off the bed while sleeping. This new mattress is a lot softer than our other, which feels more supportive and firmer. And it’s not a true queen 60” wide but instead 58”, which is quite annoying as our mattress cover and sheets keep sliding around. Can’t help but think they decreased quality to cut spending by cutting size and also foam density. Too bad. We are disappointed and won’t be purchasing another one.

    Lacking in edge support

    I had a 13 in Zinus memory foam that has served me well for about 6 years. Decided it was time for a new mattress and went with their ultra cooling 12 in (thickest available now?). I like the feel overall and the cooling of it but the edge support is non-existent. Sitting on the side you feel like you are sliding into the floor, same with sleeping if you share a bed and sleep near the edge. Will probably be returning it for these reason.

    Hard as a Rock!

    Not sure how it has such good reviews. This is a very hard and uncomfortable mattress. The middle of the mattress is creased and it never fully inflated. Biggest regret and plan on replacing it soon. Invest on a better mattress is all I can say unless you like sleeping on concrete.

    Not for me

    I have to start the return process, this is the worst sleep I’ve ever gotten. My back pain is though the roof and I need to switch back to my previous mattress that had a huge divot and two springs broken.
