  • Sleeping Like a Baby
Color: White Size: King
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. ... show more

  • Impressed!
This bed was super easy to set up. All I had to do was lay the box where I wanted the bed, cut the box off and there is a plastic wrap you have to peel off and then just lay it how you want it and cut a small hole in the vacuum pack bag holding the mattress and then watch the magic happen. It took just seconds for it to expand and pulled off all the plastic. The mattress didn’t have a smell at all. It feels soft and comfortable but firm. You can sit on the edge and it stays up. So far very happy with the fast shipping, ease of mattress shopping and a great quality mattress! I’ve never bought a bed in a box or online but after this experience, I don’t know what I was worried about. If you need a good mattress at a reasonable price, don’t hesitate on buying this one! ... show more

  • Great for bad backs
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 ... show more

  • 1 Year Update
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. ... show more

  • AMAZING BEST mattress EVER!!
FOR THE FIRST TIME IN AGES I SLEEP THRIFTS THE NIGHT WITH OUT WAKING UP MULTIPLE TIMES THE LAST MATTRESS I PURCHACHED FROM COSTCO WAS A MAJOR BRAND MEMORY FOAM MATTRESS WHICH WAS HORRIBLE THOUGH SOFT IT WAS SO LIGHT THE MATTRESS WOULD SLOWLY MOVE AT TIMES I WAS WOKEN UP AS I WAS FALLING OFF THE BED. THE MATTRESS WAS TO LIGHT WEIGHT I DID SO MUCH RESEARCH BEFORE DECIDING TO BUY THIS ONE. THE COMPARABLE MATTRESSES WERE COSTING $200 AND MORE IM RECOVERING FROM A MAJOR FALL AND I HAD BEEN SLEEPING ON MEDICAL BED THE MATTRESS WAS VERY COMFORTABLE WITH AN ADJUSTABLE AIR MATTRESS WITH A 6 INCH GEL MEMORY FOAM TOPPER I FINALLY GOT THE NEW MATTRESS READY. VERY EASY BEING ABLE TO SLEEP THROUGH THE NIGHTS WITHOUT WAKING UP EVEN ONCE!!! I DID ADD A GEL MEMORY FOAM TOPPER. I LIKE A SOFTER FEEL FRANKLY THE BEST MATTRESS I HAVE EVER SLEPT ON AT ANY PRICE WITH A COMPLETE RETURN POLICY SAVE $100s AND BUY SOME GREAT SHEETS AND PILLOWS. 👌 ... show more

  • Impressive mattress for the $$$
Color: White Size: Full
For the price, easily 5 stars. I'd compare it to a $600 mattress from a mattress store. I'm impressed. I was very sceptical too. I thought, why am I buying this? It'll be ridiculously difficult to return if it is terrible. I'll have to see how it last, but very good so far.

  • False advertising but otherwise great
Color: White Size: Full
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 ... show more

  • Save your money
Color: White Size: King
When we first got it, it was very firm. I am a stomach sleeper and my husband sleeps on his back or side. We got it for support because our last mattress caused lots of back and hip pain. In less than a year it has gone from firm supportive to completely saggy and unbearable. We are rather small people (I am 120lb and he is 170lb) and the dips where we sleep are so uncomfortable. I wouldn't recommend this bed to anyone. Save your money and get something better. ... show more
