One object · every stage
Grows with you.
For years.
One heirloom birch-ply frame becomes a highchair, chair, kitchen tower, step stool, desk and wardrobe — six pieces in one, growing with your child from six months to eight years. (It folds flat to store, too.)

More than a chair
The heirloom frame is the hero. Around it: wooden toys, soft-play, printables and stage-by-stage play plans.
The Kose One
Six pieces of furniture. One object.
From first solids to big school — around six months to about eight years. One heirloom birch frame that reconfigures through every stage, then folds flat and disappears behind a door. Add the optional slot-in second seat and two can sit across the table together.

Why Kose
One object, not a pile.
Most baby furniture is bought in a panic and stored in a garage. We made the opposite: one beautiful object that does the work of several, in responsibly sourced birch ply, built to be handed down. Kose takes its name from the Norwegian koselig — cosy, unhurried closeness.
