Bought a $5000 mattress, looking for something else

Hey y’all. I’m a 19yo male 250 lbs. Recently, after being “inspired” to put sleep first and really try to focus on health. I spent 7000$ on a 2000$ smart base by TempurPedic and a 4600$ Probreeze medium hybrid queen sized mattress from TempurPedic.

These past few chillier nights, I’ve gone to sleep and have struggled to stay warm. I understand the mattress is for cooling but this had me thinking. If I’m spending a car’s worth on a mattress, I’d better have a spectacular time with it.

Thus, I decided, dollar for dollar this isn’t worth it for me right now. I’m returning it and possibly going to get a Nectar or a Dreamcloud mattress under a thousand bucks and gets the job done. Would like suggestions, since I’m getting 5k back from returning this thing (minus 100$), have y’all got any suggestions on mattresses I should look into? I want solid value, when I sleep on this mattress it doesn’t feel like 5000 bucks, if you get me.
