Interesting lounge chair  

It's a really famous chaise manufactured by Le Corbusier, the LC4 I believe. That is, if it is genuine. As it is extremely popular there's plenty of knockoffs.

It is an LC4, which was actually designed in 1928. I have seen dozens of these over that past years, but have yet to see one that is genuine; as Kyle said these are very frequently copied.

If you google it, there are a number of sites that address how to tell if it is a real Cassina produced version. There is also a few threads on here on the topic as well, I believe. If you still have difficulty telling, there are numerous talents on this site that could probably help further.

Just want to add to the previous posts, this is from '1000 Chairs ' by Charlotte & Peter Fiell.

Thanks guys, the info helped. Unfortunately, no signature, looks like a repro. : (
