Cool Sense Memory Foam mattress - Big Lots

I just ordered this Cool Sense 10" gel memory foam mattress from Big Lots: https://www.biglots.com/product/coolsense-queen-10-gel-memory-foam-mattress-in-a-box/p810435270?pos=1:4

I can't find any info here on Reddit so I thought I'd ask. Has anyone purchased this one or have any experience with it or the Cool sense brand? It seems similar to any foam mattress with a 7" base layer and 3" memory foam on the top.

I laid on it in store and it felt great! Way better than any of the other mattresses in the store, and felt similar to the Serta iSeries hybrid I tried at a mattress firm for $1500. Ive been losing my mind for the past few months - my 10 year Serta pillow top mattress is toast - sagged in the middle and I wake up in a lot of pain each morning. I need something, and for $380 after tax I'm rolling the dice.

I'd rather take the risk that this one will wear out more quickly than a more expensive one, but know how it feels before buying it. Instead of going for a more expensive one that might last longer but I have no idea how it will feel before buying it.
