I'm doing some research for a company that is interested in using some lounge chairs similar to those in the Highline Sundeck in NYC. Does anyone know what the model name is of the movable ipe wood lounge chairs used at the highline sundeck? However, the chairs would probably be mounted instead of movable. Something like that design would be great, though.

.
E-mail contact listed top right of the link you posted.
They are custom built. (hint-sentence 5 of the five sentence copy)
"This mock-up arrived last week and is installed near the Gansevoort end."
A mock-up does not necessarily mean custom. It could be made up of various
manufactured pieces. In this instance they are fitting the custom bench and
checking how well it operates before continuing on with construction...
saves money in the long run. It also shows progress on a project that needs
funding support and donations.
If you are an intern and are being tested on your research abilities, i would
contact the e-mail address but at the same time collect close-up images of
the structures. Many other benches on the High-Line are fixed and without
track wheels. Google 'Friends of the High Line' and you will get many sites
with photos and a link to the design teams website. Good luck!
