All items are very lightly used, purchased last October, but am selling them as I will be moving out of the Bay Area in June. Available immediately except for the mattress, which will be available mid-June. Will take down/update post as items are bought. Pick-up in San Francisco Mission Bay.

MICKE black-brown desk ($40, original price $80) + whiteboard/shelving add-on ($20, original price $40). Lots of convenient storage and helpful cable organization on the underside of the desk.

It's more convenient if you'd like more than one item, so I'm happy to sell bed+mattress together for $40, everything for $100, or whatever other combinations you're interested in.

Let me know if you have any questions! I linked to all of the original product descriptions I could find, but I didn't provide any pictures of the actual items because I'm currently still using them. If you're curious to see them just let me know.
