People in my dorm last year knew me as the guy with comfiest bed. I am entirely confident this is the best set-up you can have for your college mattress...I would be keeping them if I didn't buy a new-sized bed this year (and yes, I'm buying the same exact setup in the different size). It's not cheap, but you'll see very quickly that it's worth the investment.

Stored in summer storage with protective plastic sealing wrap, and used last year with a mattress cover so it is very clean. Note this does not come with a comforter, top sheet, or pillow.

I will be on a camping trip until the 19th but will respond after then.

Asking $165 for all
