What owners single out
Buyers' concern with off-gassing smell aligns with the cooling performance trade-off noted by critics, where temperature management may come at the cost of initial material odor.
In their words
“I have bought a mattress from Nolah in 2024 and I was very unhappy with the mattress. Was very soft and was giving me a lot of back pain. I contacted the company about a month a go and explain my problem and requested a new mattress that was harder then the one I had. I was so impressed and somewhat relieved after ordering the Nolah Evolution, they agreed to exchange the mattress for me one time. ”

“I ordered the Evolution 15 plush but I was a bit worried that it would be too soft due to reviews I read online. And yes it is pretty soft but it is very good for me. I believe the medium may be good for most people. I have been sleeping very well and finding other beds like hotels to not be as good anymore. I am taking one star because of the smell and the heat.”
