I am selling this Ikea mattress base with (brennasen) legs:

https://www.ikea.com/us/en/p/espevaer-slatted-mattress-base-with-legs-dark-gray-s59207862/

I bought it $180 two years ago, and it is still as good as new!

To be picked up on campus (in studio 5) -- the mattress base is disassembled so easy to transport (and very easy to reassemble!)
