Note: it says it's made with organic cotton but the manufacturing tag on mine said it's made with 100% polyester. Like it had a brand tag saying cotton and a manufacturer tag right next to it that said polyester lol. If you want real organic/natural materials, keep looking. That said, I don't have any complaints about this mattress so far! My partner and I have slept on it every night for the last 6 months and it's been great. It's definitely firmer than I usually prefer, but I just put a topper on it and called it a night lol. It's a great budget mattress and I can see it lasting us years

I've been sleeping on this mattress for 2 weeks. Pros: I'm pleasantly surprised. It arrived on time and we'll packaged. It's firm, but not too firm and not soft. I find the edges of bed to be strong and sturdy. It's good for my back. It fits my bed frame as expected and it's pretty motionless. I've slept perfectly during my transition to this mattress. My Chihuahua has no complaints either. 1 Con: Measuring the height is a bit odd. I let mattress inflate for 4 days while out of town. Guess it's 12in but seems 11ish. Also there are spring coils on the top layer of mattress that can be felt on the sides if touched, which is surprising given this is a hybrid mattress. I'd expected more foam layers for the top of a hybrid mattress. The good news is that I don't FEEL the top springs when on the mattress. They're just felt when you touch the sides. See pics Overall, a great comfortable mattress at a great price, that so far appears to be of great quality. I'm really happy with my purchase and recommend this product.

I bought the mattress because mi e were 20 years old but very comfortable. I had slept on one at my mom’s house and thought it was nice. When I got mine and set it up I thought I was going to hate it. It felt way too firm for my liking. I bought a topper for it and had to wait for both to expand. The first night I noticed when I rolled over I didn’t struggle. I have scoliosis and did not realize how much pain I was causing my self all those years. My back needed the firmness of this mattress. When it was delivered I was going to send it back. No box and the tape around it was yellow from being old. I gave it a chance. Glad I did

Way better than I expected. It’s firm, but bouncy at the same time. My husband and I can finally sleep through the night and not wake up in pain.

I always buy Oliver Smith mattresses. I bought the medium firm, knowing it was going to be very firm from the reviews. I hate a mattress that you sink into, so I ordered this mattress knowing I could add a topper or pad to it, for my liking. When I opened it, the pillow top didn't poof up as well as it should have, so I had a couple of my grandchildren lightly jump and walk around on it. That really helped! At first I thought I was going to have to buy a topper, but I rotated the mattress to the end I hadn't slept on, which felt like it had a little more "give" to it. I think the mattress was still trying to expand. After sleeping on it for a little over a week now, it has broken in enough to where I absolutley love it the way it is. I am getting really good sleep and my energy levels have returned. I love this mattress. I know reviews matter, so I will add a little more detail: I am 185 pounds, and I can't sleep in one position. I'm constantly tossing from my back to my sides. I sleep very well no matter if i'm on my side or back. This mattress covers all of the bases. The mattress is very heavy. It's like 85 pounds. I also bought the king size "Your Moon" pillows. Now I don't even want to get out of bed. They go hand and hand!

I've now had this bed for over a year and it is still more comfortable than any other bed i grew up with. My friends always compliment how comfortable my bed is when they come over. Only thing is the middle has started to be slightly less firm than the rest because i lay in it A LOT due to being disabled so im spending most of my time in it which is understandable. I think any other bed would do the same. Also im 200lbs+ so im not the lightest person. In terms of when i first got it out of the package i had zero problems. it puffed right up and was the advertised size already. I still waited patiently per instructions before getting on it and it had puffed up even more. tldr; Love this bed. The price was more than worth it.

Sadly, medium firm is not a good description. I'm afraid whomever slept on this bed and gave it that rating must enjoy tent camping with no air matress. Even my dog side eyed me when I had her join me for the hour I tried to endure on this twin size back breaker. The best part...the return. please place bed back in original box. I'm not even joking. it comes vacuum sealed in a 2 foot by 5 foot box. it's maybe 5inches deep all rolled up. hahahaha imagine it now. 12" twin size..... in a 2x5 box. my plan. just staple box to mattress. UPS did not like this plan. I already exchanged for a canopy as I plan to never by a matress online again, so now I'm stuck with a matress I can't use (now sleeping on my couch as I sold my other bed, yes it's softer than this matress) and a canopy that I have to pay for as I can't figure out how to return the matress. LESSON HERE MY FRIENDS!!!! ....DO NOT BUY A MATRESS ONLINE. no matter the price. it's not worth the nightmare and you will never be able to return it, no matter what they advertise the return policy to be. Anyone want to buy a medium firm twin matress??? I'll make you deal! Must pick up!
