Amazing mattress!
I bought this mattress about a year ago and nothing but good things to say about it. For the price, I can’t believe how comfortable it is and it’s still in great condition. Definitely worth the purchase!!

Super comfortable
Got this about 6 months ago. It is soft but also supportive. I was hesitant about a bed in a box, but honestly I spent a lot on my mattress from a mate store and I’m pretty underwhelmed considering the price we paid. This mattress was a great price. In fact my sister has slept on this bed twice now and is usually up several times a night and both times she slept through the whole night. She has since purchased her own.

super comfortable mattress
i was apprehensive when i read hybrid mattress which means it has springs, but trust me when i tell you this mattress feels amazing. My back doesn't feel as sore anymore. My kitty and I have been having a super pleasant sleep since the purchase. The package is heavy and won't fit in a regular car if you would have to move it. It was a bit difficult to unpack but then again i was doing it by myself.

Good until the trial ends
The mattress was great at first, was perfect firmness, had good edge support but now a few months down the road isn’t holding up at all. I had to buy a different mattress to replace it because it hurt so much to sleep on. Buyer beware, once you are outside the 100 day sleep trail. You are SOL when it fails.

Great Buy!
This is one comfy mattress. I went from a memory foam to this hybrid. It is good quality, too. One thing is that it hangs over my queen size foundation, so the sides dont seem as supportive if its off a little. But other than that, its wonderful.

No Back Pain! Supportive! Amazing!
Amazing! I was nervous about a Hybrid and a mattress in a box, but this mattress outdid itself! It is true to size and has helped my back pain so much! I did not measure the thickness to see if it was true to advertisement but it is super thick! The support that this mattress provides is outstanding. Even the edges have great support. I'm glad the mattress did not have a smell when it arrived. It's a great price for what you're getting. The instructions said to give it a few days to raise, but my husband and I both laid on it like 5-6 hours after we opened it and slept great! No complains!
