The keystone holds the arch, one of the oldest and strongest and of all architectural forms. The KEYSTONE lounge chair comprises three autonomous yet symbiotic elements: a concrete back that buttresses the spine, a gently curved ceramic arch for your sit-bone, and the wedge-shaped rubber voussoir that supports and completes the arch.

The chair was originally a 450-kilo sculpture, exhibited at a Milanese art gallery in 2014. Thomas Ibsen from PLEASE WAIT to be SEATED approached its Dutch designers, OS & OOS, and said, “Why not get this down to 30 kilos and upholster it? Turn it into a comfortable and practical piece of furniture?” He then teamed up with Kvadrat to use their exclusive Raf Simons design collection. The chair has since become a collectors’ item, sold to galleries and contemporary art showrooms across the globe.

A word of warning, though: it’s not just sit-bone friendly; kids love clambering all over it. So the chair gets our one-off label: PWTBSBTOYSFK (Please Wait to be Seated But Take Off Your Shoes First, Kids).

OSCAR PEET and SOPHIE MENSEN at the Dutch design studio OS & OOS straddle the border between industrial-functional design and autonomous objects. Both 2009 graduates of the Design Academy Eindhoven, their work spans the space between concept, rationalisation and final aesthetic objective.

Will this design in its entirety, become a long lasting object, we someday can pass on to our children?

This is a question PWtbS asks before launching each product. Based in Copenhagen and founded by renown interior photographer Thomas Ibsen, PWtbS' goal is to introduce designs that have the potential of becoming classics.

The collection has its own characteristics with a focus on interaction, good craftsmanship, quality, materials and sustainability in terms of durable design.
