more from MONO - O-X and Sunrise by Lise and Hans Isbrand

 

Lise and Hans Isbrand designed two pieces for MONO - the Cabinetmakers’ Autumn Exhibition at Thorvaldsens Museum … a low wide chair called Sunrise  with shaped and curved  seat and back rest in laminated wood supported on an elegant frame in ash and a low table with a circular wood top supported on a steel frame, that for fairly obvious reasons, has the title O-X.

On the first day after the exhibition opened, there was a chance to meet Lise and Hans Isbrand and we talked about their work. They discussed the construction of the chair and were kind enough and patient enough to turn the chair over and turn it around so I could see how the frame is constructed and take photographs.

It struck me that the chair and table are different in character and form but they explore similar and related ideas about construction ... they explore how you construct as thin and as light a support as possible … with one in wood and one in steel.

Sunrise - the chair - has unusual and distinct features in it's design but is clearly in a long Danish tradition of cabinetmaking for furniture made from wood.

The seat and the back of the chair are broad oval shapes in thin laminated wood or plywood that are curved in just a single plane and that is a form of chair that goes back to the 1950s - to shell chairs designed by Hans Wegner - but where chairs by Wegner either had a bold support that was also in laminated wood or had a robust frame in wood, often oak, here, in the Isbrand chair, the seat and back are supported on a complex frame that exploits the qualities of the ash that has been used for legs and cross members that are barely thicker than a dowel and form a complicated and elegant scaffold.

O-X, the low table, also explores and experiments with the intrinsic characteristics of the materials … a large but thin disc in wood for the top is supported on a bent steel frame.

The top is about 20mm thick but the edge, rather than being cut square, has a very precise and deep chamfer that makes the top, from a slight distance, look more like a disc of sheet metal.

For the frame that supports the top, the design exploits the qualities of steel that is not just strong in itself but when bent into sharper curves than are possible with steam-bent wood it becomes even stronger as a support so it can either take a heavier weight or, as here, the parts of the supporting frame can be reduced in thickness.

If the chair is firmly within the Danish cabinetmaking tradition … a tradition of making furniture in beautiful wood, unadorned, in a sharp and precise form of construction executed with real and very obvious skill … the table is different.

It has a stripped back or pared down simplicity that reflects a specifically Danish form of minimalism. I suggested to Hans Isbrand that the table, in its style,  looks back to the 1960s and was firmly put in my place. However, the use of metal for furniture, that actually goes back to the 1930s in Denmark, was strongest in Danish furniture in the 1960s but somehow has never really competed in popular taste with furniture in wood. 

Perhaps, this was because, without deposits of iron or coal, there was little steel production in Denmark or perhaps simply because making good furniture in wood was so well established in Denmark that wood was and still is what Danish buyers choose to buy.

There are clearly great Danish pieces from the classical period of modern design that use metal - so the Super Elipse table by Piet Hein from 1964 or the chairs and tables with steel frames by Poul Kjærholm through the 1950s and 1960s - but even now there is much less furniture in glass and steel in a Danish furniture store than you would expect to see in Germany or France or Italy.

ISBRAND DESIGN

Sunrise by Lise and Hans Isbrand - MONO catalogue 26

The large oval-shaped seat and the backrest of the chair are in laminated wood or plywood that are curved in just one plane and rest lightly on a thin and elegant framework or scaffold in ash.

Ash has a straight and regular grain and this is exploited in the construction with the parts of the frame turned and reduced to a small cross section so the pieces are barely more than the thickness of a dowel.

For a framed chair in wood the simple and common form has a square or circular frame that supports the seat with, normally, two legs at the front, often but not always housed into the underside of the frame, and with two legs at the back that continue above the level of the frame to support a piece of timber for a back rest that is set either vertical or at a slight angle for more comfort and is either between the upper parts of the back legs or fixed across the front of the two uprights. To keep the legs in place the next stage is to add stretchers - lengths of timber between the legs to stop them splaying out and if stretchers are added then the timber of the legs can be thinner.

It doesn't really have to be spelt out like that here except that it shows just how many of those conventions the Isbrands play with and subvert to create such an elegant framework of wood to support the seat and the backrest of their chair.

The other basic elements of construction that should be pointed out is that horizontal and vertical parts of a chair are usually fixed together with mortice and tenon joints with the mortice or slot in the main and usually thicker timber and the tenon or tongue that is fixed into the mortice is usually on the end of the thinner secondary timber. The classic ways to stop the tenon pulling out is either to drill a hole through the side of the mortice and tenon and drive through a peg to hold the two pieces together or to cut a slot across the end of the tenon and, when the timber is in place - with the tenon in the mortice - then a wedge is driven into the end to expand the tenon and stop it pulling out. The strength of the joint is greater the more precisely it is cut and often it is the shoulder, at the point where the timber is reduced in size at the start of the tenon, that has to be well cut, to keep the pieces at the right angle,

In Sunrise the tenons are rounded off at the top and bottom to form an extended oval shape and there are two wedges in dark wood to keep the tenon from pulling out so this becomes a strong decorative feature of the chair frame. The tenons do not have a pronounced shoulder but there are hollow curves back from the joint itself to make the transition from the tenon to the full thickness of the timber.

The frame is complicated. Perhaps the most conventional part is the front frame with two vertical legs with two stretchers - one just below the top of the legs and a second stretcher just below that.

The two back legs are set out at a pronounced angle and do not support the back rest directly but are housed into short verticals that support the back rest and are rather like props. The two vertical supports for the backrest do not run down to the ground but are housed into long raking struts that run from the top stretcher between the front legs angled down and out to the back legs.

The laminated seat rests at the front on short collars or spacing pieces housed into the top of the upper stretcher and the back of the seat is supported on short brackets out from the lower part of the struts that support the back rest.

Again, as with the front of the seat, there are short spacers between the struts and the curved back rest.

To stop the back legs moving outwards there are low stretchers, just above the ground, between the front and the back legs.

There are very nice details to the frame like the deep cups shaped out of the tops of the legs.

Rather than having upholstery or a cushion for the seat there is a simple round hole cut through the laminated wood that is closed with halyard taken from side to side, woven by threading the rope down through small holes drilled around the opening.

O-X by Lise and Hans Isbrand - MONO catalogue 38

This is a simple circular top on four short steel legs but those legs are not fixed into the underside of the top and are not part of a frame on cross struts immediately under the top but are set outside the rim with the top of the legs bent in a relatively sharp curve inwards and inserted into hole in the rim where they are held in place by a grub screw from below.

At the floor, the legs are linked by cross piece to the leg diagonally opposite. These X pieces might have met at the centre but they are arched upwards but each with a different curve so one crosses over the other.

The edge of the top could have been cut to form a simple flat face or could have been given a rounded profile but is undercut with a sharp chamfer. Wood cannot be cut to a thin sharp angle but here the vertical at the top edge of the chamfer is as thin as possible and that makes the top, for its size, very elegant.

This chamfer could have been stopped square or angled off but is swept down and then back up to form a vertical where the top of the leg goes into the top of the table. They are held in place by small grub screws.

A large but elegant and deceptively simple but sophisticated table.
