I've been sleeping on this mattress for 2 months now, so here's my review. I saved my tax return for a new mattress as I really needed a replacement but ordering from Amazon was most convenient aside from not being able to try it out before using it, which made me nervous. Despite having good money set aside I really didn't want to spend more than $300 and had a handful of mattresses saved on a list. I can't remember if this one was on sale or not but it was just over $200, I believe and I'm blown away really. It arrived early, I had no issues with delivery, and I had a good space to open it and let it unroll and stuff. I also read in the instructions walking on it periodically helps with airing it out and getting it to the right size. As soon as it seemed "inflated" I laid on it to test it because I'm impatient lol and WOW! Seemed too firm at first so I was nervous but once you settle on it, it's very cushioned in a sort of "cradle" way. It doesn't give too much so you don't sink deep but it is very comfortable. HERE'S THE BEST PART (personally). I have struggled with insomnia for years. I've been regularly medicated since 2019. This mattress got me off my very sensitive/strict insomnia medication, NO LIE. Who knew all I needed was a better mattress? Not me, but on top of that, my hip and back pain have improved significantly and I sleep through the night most nights (unmedicated!!). Very personal results, but it's important to note. TLDR; it seems firm but when you settle on it, it's very comfortable, eases back pain, feels good quality, and was well worth the price. I would recommend it to people whose needs for a mattress are similar to mine.

It’s very firm when you first get on it, but eventually you’ll sink in. I get pretty hot at night, so this mattress also kept me cool. A very nice mattress overall and very worth the money!

I needed a good mattress that is supportive yet soft enough to not cause pain in my aging hips. I am absolutely mystified at how nice this mattress is for the price. It "fluffed" up rather quickly, which was surprising. It is very comfortable, and truly a medium firmness as described. There is no motion transfer from my husband moving around. It was delivered on time. I highly recommend this mattress! I went with a 10" mattress because it is not as heavy, making it much easier to change the sheets.

Super happy with this mattress! Came in a box, super easy to set up, and it puffed up right away. It’s that perfect medium feel—supportive but still comfy. I don’t wake up sweaty anymore thanks to the cooling gel. Totally worth it for the price!

This 14-inch king mattress is the perfect balance of softness and support. The extra height gives it a premium look and makes getting in and out of bed much easier. The memory foam layers feel soft on the surface but firm enough underneath so you don’t sink. The thickness provides full body support without losing shape. Great functionality at a great price.

We ordered 2 twin x for our adjustable beds. They arrived quickly in the afternoon and we put them on beds next morning.No noticeable smell and the 12" medium firmness was just right. Only used them for a couple of weeks so cannot attest to long term long usage.

I recently purchased this mattress for my parents and turned out to be a perfect choice. The height is just right, making it easy to get out of the bed for them and the noise level is practically nonexistent, so during night doesn’t disturb sleep. The expansion rate after boxing was fast and the functionality is excellent whether for sleeping or lounging. They haven’t experienced sinking problem and support is firm yet comfortable. Overall a great choice for in terms of sleep.

Like the dark color which is nice to help prevent stains from showing over years of use. The mattress was easy to setup and feels firm but not too hard. It is comfortable on my back and seems to provide good support. The price was great for the king size and arrived quickly. Would recommend and buy again!
