I’ve been sleeping on this Zinus mattress for a few weeks now, and I can confidently say it has exceeded my expectations. The combination of memory foam and innersprings provides just the right amount of support while still feeling incredibly soft and comfortable. I wake up feeling well-rested and without the back pain I used to have with my old mattress. It came vacuum-packed and was easy to set up—just unbox, unwrap, and let it expand. There was a slight smell at first, but it went away quickly within a day. The quality of the materials is excellent, and the mattress feels durable and well-made. If you’re looking for a budget-friendly mattress that doesn’t compromise on comfort or quality, this one is a fantastic choice. Highly recommended!

I have a king sized Zinus (green tea cooling) and love it so much for the comfort, ease, and price that when my kid desperately needed a new mattress, I immediately turned to Zinus again. It's perfect! Really reasonable, easy to receive and set up, and very very very supportive yet comfy. We paired it with the Zinus metal platform frame and it is just lovely. Highly recommend.

I bought 3 for my kids. They all think they're comfortable and I liked it because it's affordable. Haha. Win win. It's a good balance between soft and firm. Good support. Works well for what we need. Doesn't really make any noise from what I've seen.

Lovely bed. I got this bed and was sceptical of ordering it online because you can't test it out. But I get great sleep. It is firm enough to not hurt my joints yet soft enough to be really comfortable. It's just right. I don't overheat in the Summer. And I wake up feeling like I got good rest.

For the price it’s good. I should have purchased the 10 inch. But it does its job, I sleep through the night. No aches or pain. Had it for almost a month already. Was in the process of moving and was delivered perfectly in a medium-ish sized box

This is a great mattress for the price. It is thin, but has held up well so far and after putting a mattress topper on it is very comfortable to sleep on. Our guests have been comfortable sleeping in this bed!

Today is 5/3/2024. I purchased the Zinus 10" Foam and Spring Mattress on 5/23/2024. I probably got it a few days later. My point is, it has not even been a full year since I purchased and began using this mattress. At first, everything seemed ok. I figured that there were so many reviews, so this probably was a good buy. WRONG. Things were fine for the first three-four months. Then the springs would SPROING! every so often while I was laying in bed. It's pretty disturbing when that happens- it's kind of a jolt! I also want to mention that I am a rotater and a flipper. Every month I rotate, and then next time I flip and do the same again. This is to prevent sagging in the one area I seem to only sleep in. So, the sproinging started up, and that was bothersome, but not terribly so to make me actually do anything about it. But a few months later, the sagging really started to be noticeable. Like, I could feel myself rolling down into the pit of sagging despair. It wasn't just on the one side, it was on all the sides. I think this might be the foam degrading- which it shouldn't be doing after such a short period. It's only one average size woman sleeping in this bed and I'm not bedridden- it's 7-9 hours max a night. A few months ago I had enough. I couldn't even remember how old the mattress was, and this was what prevented me from being fully motivated to doing anything about it- I think I thought the bed was older than it was. I don't even remember what I was doing a year ago, and I don't remember getting the mattress or setting it up- it just feels like it was much longer ago than it was. But, I keep seeing these ads on TikTok and IG for these Nectar adjustable beds and I'm like- god, my old bag of dust mites bed really sucks...I should do something about it. That's when I looked the order up and was shocked and surprised when I saw how recently I had purchased this bed. As a reminder- it is LESS than one year old. I was like- sweet- it must still be under the one year warranty- problem solved. I emailed the seller and told them what was up. They asked me to send pics. I sent pics. Then they asked for more pics, I sent pics. Then they asked me to strip the bed, flip the dang mattress and take a pic of the tag. I sent a pic of the one tag. BUT THERE WAS A SECOND TAG. And this tag was removed. What in the name of sleep number is going on here? Everyone knows that the tags are allowed to be removed from items by the consumer, even when they say it's against the law. I mean, I googled this, and you can, too. But NO. Zinus says that since their tag was removed it voided the warranty and this ten month old mattress was my problem to deal with. Look, this piece of crap only cost $150. So it isn't the end of the world. You might say I got what I paid for, and I would now agree. But at the time, that was my budget and the reviews convinced me this was a solid product and I assumed any company worth their salt would stand by a mattress LESS THAN A YEAR OLD. If my mattress was 5 years old, I could understand this. BUT IT IS LESS THAN A YEAR OLD. There is seriously NOTHING outside of me taking a machete to this thing and slicing it up that should preclude this company from standing by their product. If this thing cost me $150, then it cost them around $100. I guess for a measly hundo, they get to have a very unhappy customer who happens to have nothing better to do this weekend than to write reviews about how bad this product is and post it on amazon and all my other sm. If I prevent one person from not buying this mattress, that will have cost this shady company more than it would have to just do the right thing and take their saggy mattress back and replace it. This makes no sense! There is a reason why mattresses don't cost $150. It's because a quality mattress costs more than $100 to produce, even if you use elementary school-age kids in some third world country to make them. The cost of freight alone makes this impossible. I work for a commercial furniture dealer and we are in the process of importing 3 containers of custom casegoods from China. I know exactly how much this costs. I should have known better but again- the reviews- and I could afford$150! You absolutely get what you pay for. For comparison, the average name brand mattress sold in the US has a warranty of 10-20 years. Some even offer lifetime warranties. The average life span is closer to 7-8 years. I will end up spending twice as much if I have to buy a new mattress every 10-12 months if I continue to buy this mattress. Imagine the waste in the landfill if me and just a few other people go thru a mattress a year! Plus, I have to deal with disposing this thing, which isn't free, and it is a pain in the backside to haul it downstairs and to the alley. I'm going to a mattress store this weekend. There are a million of them around, and I will just go and check out a few. I need to shell out at least $400-500 and get a decent product. Good sleep is probably more important than the food you eat. I just can't take it anymore. If you are a college student who doesn't plan to take their furniture with them every summer when you leave your apartment, perhaps this is a good idea for you. I still think it is horribly wasteful and terrible for our environment, but I can understand if you live across the country and unable to store it or move it back with you on the plane. Or if you are very low income (been there- kinda am there still), and you absolutely cannot get anything better, I understand that, too. But if you are a regular person with stable housing, a relatively decent income and want to buy a mattress that you can count on for good restful sleep, you need to really consider not purchasing from this company. If only because it is absolute nonsense they wouldn't stand by their $100 product that is less than a year old even when presented with evidence that it is bad. And if you must deal with this mattress and seller, for the love of stearns + foster, DON'T REMOVE THE BLOODY TAG!
