All you need to know about mattresses ☺️
Size: Full Style: 12-inch Pattern Name: Medium-Firm Feel
So you're looking for a mattress! My guess you're overwhelmed with options and info. It's no brainer sleep is important and we want the best for our health/money/comfort. Well I'm here to give my guidance! So when buying a mattress you always want "the best". Sleep is critical for every function of our lives. So it's very natural to humans to believe the more you spend quality reflects as such. Here's the deal with mattress, that is simply not the case! A lot of higher end mattress brands you would be shocked to know how much commission is into the price of the mattress for the floor associate. So now you're stuck looking at affordable mattresses online that you can neither see nor touch. But you're supposed to spend a third of your life on. Well that's no good! Well let's make it simple. Foam mattresses are the best currently on the market. Period. The spine support they offer. They run significantly cooler, this one especially. Durability. Quite. Ease of use (no box springs). Let me make this very clear the foam mattresses win every way over other mattress types. The only con to one is they might smell for a day or 2 when you first get it but it quickly goes away. Okay great so foam it is. Now firmness what's the right one for me. Good question in fact this is the number one priority for a mattress. What happens too often you want to sleep on a cloud or a pillow. Absolutely not. What happens on the super soft mattresses is you're swallowed by it and your back isn't properly supported/decompressing. THIS IS MEGA SUPER IMPORTANT. What happens is when your back is arched like that the vertebrae of your spine touch and here comes the back pain. The only time a super soft mattress is recommended is for a super light child 60 lbs or less. I'm 135 lbs 5'9, scrawny and still too much for even me. Reason being is because the child being so light won't sink into the mattress which will give good spine support and gravity can do it's job. It's all about the spine. This mattress sits a medium firm. Going more towards firm and is absolutely wonderful. My first night I switched from the squishy cloud mattress to this. My back laid flat and gravity allowed it stretch out and decompress. I was literally gasping for air equivalent to a good massage over how much my back was compressed over the years. This mattress is perfect for the average consumer. I will say heavier folks go with a firmer option. This one runs cool. Easy to change sheets on. Priced unbelievable! Can't say enough good. Don't let the mattress stores scam you thousands on a brand, this is the one for you! ... show more

Can’t beat the price
Size: King Style: 12-inch Pattern Name: Medium-Firm Feel
For the price you really can’t beat this mattress. I accidentally ordered the soft one two years ago and I just dealt with it and I slept on it. It was fine. It’s time around. I need a new mattress and I decided to go with the firm because it’s what I really needed and this mattress feels so much better than the soft one. I read that sometimes it made sag if you were just using a wire metal base so if you do use that, I’d probably try to put some wooden planks underneath it. I’m gonna try it before mine starts to sag but so far it has been joy to sleep on. I have a broken back from a really bad car accident nine months ago and this mattress has been a pleasure to sleep on. ... show more

FIRM, No "Medium" About It
Size: Full Style: 12-inch Pattern Name: Medium-Firm Feel
This is a very well-made mattress, but I took off one star because there is NO "Medium" to the firmness - it is definitely FIRM. As I have no way of shrinking it back into its box, I cannot exchange, but wish I could.

Great mattress…for the kids!

Review Image by Just Us
This is a GREAT MATTRESS! For your children. If you’re a 50 year old thinking a $200 mattress is going to help your back, then there’s something wrong with you. Spend $200 on the kids whose bones are made of rubber. Go to Mattress Firm for that 2k mattress for the degenerative disc disease you’ve got. It’s a real no trainer! 🙄🙄 ... show more

Do NOT buy
Size: Queen Style: 8-inch Pattern Name: Medium-Firm Feel
ABSOLUTE waste of $200. Ordered medium firm and I got the softest, cheapest mattress I've ever had. (And I have owned many). As for returning- they are fully aware you're not even attempting to fold this massive thing up to box, and ship back for a refund. So they can get away with it. This mattress is garbage. Please take this review seriously. I will make sure I post it everywhere possible in case they get it takem down. I will add pics and video soon. ... show more

Not nearly as firm as previous versions.
Size: Queen Style: 10-inch Pattern Name: Medium-Firm Feel
I have two of these medium-firm mattresses purchased a few years ago and absolutely love them BUT i just ordered a third and it is NOT medium firm. I also have the plush version, which I wanted to replace. The new medium-firm is as soft as the plush mattress that I was trying to replace. Having both to compare, I assumed they sent me the wrong one. Amazon sent another...and it was just as soft. Apparently they have a new manufacturer. I cut open my old medium firm and it was 2" of memory foam over 2" of another layer over the base layer. The new one is 3" of memory foam over a 2" layer over the base, and both the upper layers feel softer to me. I'm very frustrtaed because the old version was the perfect mattress for me, and now I will have to begin a new search. Amazon took care of me in terms of a refund, which is good...but now I don't have a decent mattress and don't know what that will be. The previous version would get a 5 out of 5 (actually 6 out of 5 if that was possible). I don't know who makes them, or how to try to find the previous manufacturer. ... show more
