I bought our bed when I was pregnant with my first child. At the time, I thought I needed an extra soft bed, so I got the most plush bed with a pillow top that I could find. I spent a lot of money on it too. Almost six years later, this bed is way too soft for my taste, and it is lumpy because of the pillow top. Also, the side where my 250 pound husband sleeps is like a ditch!
I will be looking to buy a new bed soon too, and this time, I plan on getting one without a pillow top. My suggestion to you is to buy a mattress from Costco. I have great luck with almost everything I buy there. If you don't like the mattress, you can return it for a full refund. Good luck to you. I hope you can get a comfortable night's sleep soon.
