Ultra high end Brazilian furniture maker Tidelli, responsible for posh outdoor furniture at commercial venues and designer residential.  Circa 2016-2018, we have 2 very good condition (excellent condition but the cushion fabric is a bit faded) Iaia Lounge Chairs as shown.  They could use a bit of cleaning but are in amazing condition for their age - would have guessed 2 years old at most from first glance.
 
Extremely difficult to find - now discontinued everywhere.  Two sources of info:

It is believed MSRP was at least $1800 if not more per chair when new.  Cannot find any for sale now - however, we did locate this Sotheby's sale for another lounge chair by Tidelli listed in very good condition for $1,890 here:

Selling these stunning beauties for $365 each.  They each have leveling feet, and velcro for the seat pads - all cushions unzip to wash.  Just have the pair and prefer to sell together.
