Would you purchase a goose down or a 4 inch foam mattress pad?

I have a firm Chiropractic Mattress, which 3 years ago was great but now I just find it to firm and uncomfortable. I have heard some people rave about goose down but I don’t want to soft or something that will be flatten in a few months. I have researched memory foam pads and it is recommended to purchase 4 inch because it maintains its shape longer.
Curious what the masses recommend.
Thanks

I have a goose down “feather bed” topper in my guest bedroom…so comforting to sink into when I want to take a nap. The “down” side to it’s everyday use is that you have to re-fluff them after use to keep it fairly level, even if the down is sewn into channels or squares. It needs fluffing, just like a feather pillow does. On my bed in the master bedroom, I have a very firm mattress with two 2″ memory foam pads. I got the 4″ depth which is soooo comfy, but when I want to change anything with the bed, the toppers are easy enough to move around. A single 4″ would be too heavy and cumbersome to move. They also maintain shape very well. Another consideration is making the bed. When you have a feather bed, the top comforter or covering does not look flat and pretty. When you have the memory foam pads, it all makes up nice and flat. I purchased mine from Sams Club, and they were a very decent price….well worth the excellent night’s sleep.
