I did not buy this directly through Amazon at the time, but directly through the manufacturer (which had a sale going).The first nine months to a year with this bed was fine/great (4 to 5 stars) -- well worth the great price.Around the year mark it started becoming uncomfortable. So, since I had purchased a queen size, I rotated (not flipped) the mattress so that I would sleep on the less used side.Here I am now at the 1.5 year mark, finding that it is very uncomfortable. My back is the primary instigator of my discomfort (too much pressure on it due to my hips/shoulders sinking into the bed).I'm an average height male weighing around 170lbs. If I can't get a topper to help this bed, I'm replacing it. Though... I'm starting to believe that one should spend their money where they spend their time -- and not go cheap.For $300-$400, for a years worth of comfort... not bad. Sadly, yet also a plus of the mattress, there is no sensation or observable artifact of the bed forming dips/bowl shape, so getting in on a warranty probably won't happen. It looks as level as the day it unrolled.This will make an excellent guest bed!

Excellent quality for the money. Very firm mattress but not hard. I am a side sleeper and have zero issues with being uncomfortable.Two question Ive seen asked here and on Wayfair (where I ultimately made my purchase) was about it not having any support foam on the sides and the size of the bed once fully expanded.For the support foam it has not been an issue for me what so ever. It's actually a bonus as instead of having just foam around the perimeter you have coils that go all the way to the edge giving you much better edge support compared to mattresses that have a foam border.For the size be aware that at least in my mattress (10"queen) it is in fact about 2 inches longer and around an inch wider than what a queen mattress should be. I notice on my basic metal bed frame with box spring that the foot end hangs off noticeably more than the queen mattress its replacing for example.

The first night I was unsure, after the 3rd night... I'll fight you if you try to take my mattress. It's absolutely my favorite bed ever. I enjoy it so much I will recommend it to people... Unsolicited. It's the best pro life tip they will get this year.

We searched for a cooling and firm mattress for months !!! Finally came across this mattress online. Decided to give it a try . We LOVE it ! Solid and firm but not hard ! Cool to sleep on and love the simple cover. We are very pleased !!!

Great mattress very happy with itEasy and worth it ..would buy again

Firm, no smell, back feels so much better - what a deal for the quality! So happy I made this purchase.

no chemical smell

This mattress is not uncomfortable and yet not exactly comfy either. It did give me a mild backache. But worse than that is that whatever they use in it, this thing smells God-awful. Even the FedEx guy who stopped for a delivery today smelled it and said it was awful. I have chemical sensitivities and thought this would be a safe and affordable choice but nope....I had sinus and respiratory irritation, dizziness, headache, fatigue, etc.I ended up not being able to go in the bedroom at all after a few days and had to sleep on the sofa in the living room until a new mattress arrived from another company. Thank you, Amazon for refunding my money! I appreciate you standing behind what you sell!

So far this mattress has been extremely comfortable ! I hope it remains in this shape for years to come.

Great comfort delivered right to our door at less than half of what the mattress retail stores are asking.SO GLAD WE BOUGHT THIS!
