Arper’s Adell and Leaf both work as indoor outdoor seating. Adell is a compact lounge chair with a shell of 80% recycled polypropylene. Leaf is a family of chairs, stools, and tables in powder-coated steel rod. Both take their cues from natural form, not a patio catalog.

Adell is the stone. Lievore + Altherr Désile Park gave it low rounded curves and a concentric surface texture pulled from tree rings. The shell comes exposed, with a seat pad, or fully upholstered. Bases run sled, four metal legs, or wood. It disassembles for recycling and goes together without glue.

Leaf is the branch. Lievore Altherr Molina drew it in 2005, veined like the thing it is named for. Arper updated it in 2025 with removable upholstered cushions. That is the version that matters here. Comfort was the one thing the original asked you to forgive.

Depth is the appeal. Chairs stack. There is a lounge chair, a chaise longue, and a stool. Coordinating tables in Compact HPL come ovaloid, round, or square.

Specifiers get useful coverage from the pair. Leaf takes weather and takes it lightly, which suits a rooftop or an amenity deck. Adell leans softer and holds a waiting room or a lobby without changing register. Run them together and the outdoor seating stops reading as a separate scheme.

Arper has been reworking its own back catalog with some discipline lately, most visibly in the Catifa (RE) 46 reissue. Adell and Leaf apply the same thinking to the threshold.
