I know there are some IKEA/Habitat furnitures and products in the two UMA shops opened so far in Hanoi. The closest to the center is the one on Kim Ma (exact address is 2 Tran huy Lieu/A5b Giang Vo, Kim Ma street). Good prices, too.

You can check out Beyond (305 Kim Ma). They have a few IKEA products at rather high prices. But frankly, I'd rather go to Bangkok and Singapore to get all the stuff I want, especially when Air Asia and Tiger Airways offer low-priced tickets.

in addition to UMA (1200 m2 of ikea style producys in My Dinh..), I saw a shop today on Ly nam de selling some Ikea products...
