Worst mistake ordering dreamcloud. Zero edge support. Sinks inches deep, not firm

Ordered a dreamcloud premiere hybrid. Day 2. It is awful. It is not firm it is plush. I had a firm with a eurotop from Serta for 12-14 years. LOVED IT. THIS MATTRESS IS A NIGHTMARE. I’m so miserable. Now I’ll have to start looking again. And from what I read, the mattress will only get softer. It will not get firmer. So by the end of this 30 days, I could be sunken into the platform of my bed.
