Zinus 12 Inch King Foam and Spring Hybrid Mattress, Medium Feel

Amazed how great this mattress is! I ordered this on prime day after a long search for mattresses. It is for my daughter who is moving to another state. It arrived fast and was simple to take out, the day after it arrived. Left it laying flat for 3 days before putting it on the frame. It's amazing how great it looks. You'd never know it was rolled up tight in a box. It is being used on the Zinus metal frame. Comfortable mattress for the price. I slept well on it, no back pain and my quality of sleep is great. Very satisfied

I did lots of research between this and other mattresses. I did go up in height of mattress which I wasn’t expecting, but the 12” was $10 more than the 10”. I bought the twin 12” and was concerned it’d be firm but actually very soft. I’d say medium soft. However I think cuz it’s 12” it’s very tall it’s very squishy and moves a lot. I am an adult who’s heavier and everytime I change sleeping positions the bed shakes everywhere. But is still very comfy despite it being very shaky.

I am correcting a prior review of this mattress. I had not given it enough time to fully fill out and now I find it very comfortable My problem is my adjustable frame does not truly match the mattress exactly so it hasn’t got enough support on one side. But the mattress is comfortable and I’ll have to come up with a solution.

This mattress is pretty comfortable, it does have a few flaws like some lines and such that aren’t even.

Super constable & very soft material doesn't dent always fluff

I’m was excited about this new mattress, and it’s disappointing to be writing this review. I’m considering going through a return for it. I thought I did my research and felt pretty confident because I recognized Zinus as a brand, similar to the Linenspa mattress we use for a spare room. The biggest issue is that .our Zinus mattress feels hot. Since getting it, I haven’t been able to sleep with blankets, just a sheet. Even with our air conditioned blasting. It doesn’t feel like it permits airflow very well. Rechecking the ad, it doesn’t say cooling, but it seems like a reasonable, basic expectation for a mattress like this. Many others say it. I just assumed this one would be too. I stay away from the Tempur-Pedic foam bricks for that reason. But hot sleepers beware of this one, It is way too soft to be labeled ‘medium firm.’ Some of the other reviews seemed helpful in grading the plushness with the height—14 inches more plush, 12 inches more firm. 10 would be too low so I went for the 12 thinking anything labeled medium firm would safeguard against my hips sinking lower than my body while on my back…but that doesn’t seem to be the case. That also doesn’t help the air flow issue. I would always prefer to lean towards more firm then add a topper. I think any use of ‘firm’ in the ad is misleading for this one. It transfers movement worse than the queen we use in our spare room, that’s older, also a hybrid from a box, and a smaller bed than the king. I’m writing this review in the middle of the night after my spouse left for the spare from being uncomfortable. Overall I’m super sad about the mattress. It looks nice, inflated quickly, and was delivered fast, But the important stuff was a big miss.

My 3rd Zinus king. First one a foam lasted 8 years, 2nd one foam only and a dud. Primary bed is a Sleep Number which is great but this one gets used a few times per month at vacation home and honestly is the best one ever. Love the hybrid! Highly recommended

After using for a month every night, I'd say this mattress is medium firm, you sink in the top a little but the springs stay firm. Once you open the package it quickly rises to full size. As a hot sleeper, it doesn't do much to keep you cool (but neither do most mattresses with this claim) but it doesn't make you overly hot. It's not bouncy and I can move without disturbing my cat if she's next to me. If you aren't looking for the perfect bed this is a great mattress. It exceeded my expectations.
