Seeking to Swap Mattress: Bigger for Smaller

Hey folks,

Does anyone want a king-sized mattress and are willing to swap their Queen or Full-sized mattress for my king-sized mattress (and box springs)? (No twins). I just inherited a king-size mattress from a trustworthy friend but we didn't have the strength to get it up the stairs! It's too big and heavy. I can see having a King-size being a recurring problem for me being it's so big and I'm nomadic and usually occupying small spaces. If you're down we can arrange a swap party. Can anyone help?

I'm in Prospect Heights, Brooklyn near Grand Army Plaza.

Please contact me directly.
Thanks for your help!
