Mattress explodes-no kids, pets, elders at opening

So far, so good! We just put it on the boxspring….so, I will update this a bit later. For under $200 , I am super pleased thus far. Mostly, I am writing this to say…this mattress explodes out of its wrappings . Be advised! We had the mattress roll at the headboard, unrolling the clear plastic…reached critical mass…and wow! If my 88 year old mom would have been standing at the bottom of the bed, ( supervising), I would now be motherless. 👵🏻

Surprised, shocked and happy all at the same time!

I'm extremely surprised, shocked and happy all at the same time since my Sweet Night Island mattress came in last week! I was very skeptical, because 4 years ago I bought a Zinus hybrid from Walmart, and it was so hot I couldn't stay in the bed. I was sweating, and it was a 25 degree night outside, so it wasn't the middle of the summer. That tainted me against any memory foam mattress, so I bought a Costco Beautyrest latex mattress. It was fine until last year, when it started developing a ridge in it, so I chatted with Costco 3 weeks ago and they gave me a full refund. I couldn't find a decent latex mattress for less than $1000, and I wasn't sure about that one (a Sam's mattress), so I kept doing my research. I looked at Purple, Casper, and all kinds of mattresses until I was tired of looking. Then I saw the Sweet Night above. I figured I'd take a chance on it since I could do the same thing I did with the Zinus - roll it up in the back of my truck and take it back. I got the Sweet Night last week, unrolled it and tried it out with no mattress topper. It's pretty firm but very sleepable, so I put a mattress topper on it. It's the best money I've spent in a long time! It comes with a 10 year warranty, but I'm thinking if I get 2 or 3 good years out of it, I'll be fine. Maybe it'll keep on surprising me. Sorry for the long post, but from a 225 lb. 6'-6" warm sleeper, I'm looking forward to the Sweet Night future.

Best Mattress Ever!!!!!!!!

This is one of the best mattresses I've ever slept on. The firmness is just right. If you're having back issues then this is the perfect mattress for you. It was also a steal. I just could not believe the price.I read the reviews over and over again to be sure and they did not disappoint. You will not be disappointed!!!!!!!!!!
