Solid wood, unfinished that appears to be pine but might be rubber tree. Ordered 2 and received 1 on October 1st. Not much assembly required, just buttons to cover bolt holes required hammering.
Unfolded and latched into place, as instructions said.
Product of Thailand. Number 83 of 1200 arrived scratched but intact. 
Serviceable for DVDs or light bric-a-brac but not for heavy books. Happy camper, because I didn't expect too much in way of quality.
