The previous tenants at our new place left this large -- and for us,
unnecessary, but otherwise quite nice -- black particle-board shelf
thing that is about six feet tall and not much less than that wide
(sorry, haven't found the tape measure yet), so it won't fit in your
car but might fit in a pickup truck/very large SUV/van. It is probably
dismantle-able, but we haven't tried yet.
It's out on our porch on Whittemore St, a one-block deadend street in
Arlington Center right off of Mass Ave, and anyone is welcome to come
by and take it anytime. It doesn't have a spot large enough for most
TVs, but would be great in a child's room, artist's studio, bedroom,
etc. for organization. Has a miriad of shelves and four small drawers
that can be opened from either side of it, so you could potentially
have it accessible from both sides.
