Our current king-sized mattress is almost 9 years old. I’m not sure it’ll make it to 10 years. As a result, I’ve started my research on different mattress products. We currently sleep on a traditional innerspring mattress with a pillow top - what I would call medium firmness. It seems memory foam mattress technology has really expanded and there are more new companies selling this type of mattress than ever before - Casper, Endy, Dormia etc.

My perceived concerns ...
Memory foam = hot ...
and may need to be kept in a room with a minimum temperature of 68-70 degrees to fully function
Innerspring = more pressure points on an aging body

What do you sleep on? Do you love it? Why? How often do you replace your mattress?
