This is a deceptively simple but very clever design - like a child's drawing of a chair or a cartoon drawing of what a chair should be like - a chair that should be in a Walt Disney cartoon like the Sorcerer's Apprentice - but beautifully realised in wood.
With rounded corners and rounded edges it's the very opposite of thin and elegant so it is somehow comforting and it brings out the soft, warm and almost gentle, qualities of good oak in a way that is found too rarely in modern furniture.
The seat is solid and not round but squarish with strongly-rounded corners and the edge of the seat is rounded off with the most pronounced rounding on the top edge rather than it being a symmetrical moulding or being undercut. The four legs are robust and turned - so round rather than square in section - and tapered - so wider at the top and narrower at the ground - and the foot is not cut square or flat but also has an obvious rounding.
The legs are set directly into the underside of the seat but into blind mortices * and they are angled outwards slightly for stability. Because the legs are relatively thick, stretchers that are necessary in lighter and thinner chairs to stop the legs splaying out or twisting, can be omitted here.
The back rest is substantial and sharply curved - in the horizontal plane - embracing the back of the sitter but is not in plywood but is cut from oak and again is given a softer, smooth shape with rounded corners and rounded edges. It is supported on four robust flat splats - rather than turned spindles - and again the edges are smoothed round and, like the legs, these splats are held in place with tenons in blind mortices so no distractions from anything as complicated as a peg or a wedge.
Maybe it sounds silly to say this but it seems to be a deliberately unpretentious and an amazingly open and friendly chair. To use a phrase normally associated with candles - this is hyggelig.
* In simple furniture, particularly in what is often called country furniture, the most common way to fix turned legs to a solid seat is to cut a round tenon at the top of the leg and, with a hole completely through the seat as a mortice, the tenon is held in place by cutting a slot down through the tenon and once the leg is in place, the tenon is expanded by driving in a wedge from the top. The strength of the leg depends on the precise and sharp cutting of the mortice and the shoulders of the tenon.
