The Owl Adjustable Rocking Chair

Comfortable rocking chairs are challenging to design, as they are dependent on a wide range of variables – one’s height, weight, centre of gravity and leg length. Some furniture makers use an adjustable chair to get the client’s measurements before embarking on the design and build process.

Dennis has just completed a Masters Degree in Furniture Design at Bucks New University, High Wycombe - the National School of Furniture. He was awarded a distinction for his work on the 'Owl Adjustable Rocking Chair' - a world's first.

Dennis built an adjustable test-rig, which everyone loved, but instead of him making bespoke chairs - consumer research showed that everyone wanted an adjustable rocking chair. The adjustments had to be easy to use, so he used the ratchet concept from the deck chair and developed it further. With the precision of modern CNC routing he was able to incorporate simple ratchets into the plywood body design. The rocking-chair's back-rest rotates around a hidden axis based on the approximate position of the hip-joint.

The 'Owl' adjustable rocking chair has a sculptured seat, originally based on a mould of Dennis' bottom; it has an adjustment for height (leg length) on the rocker; it has an adjustment for the seat tilt at the front; it has an adjustment for the rake of the back-rest; and it has adjustment for lumbar support on the rear of the leather back rests.

Each chair is cut from one 4’x4’ sheet of plywood and takes 55 minutes to machine. The chairs do not need to be assembled in the factory by costly labour; they are supplied as a flat-pack - the customer assembles the chair. The chair can be manufactured economically anywhere in the world – the only requirement is a sophisticated CNC Router – so why not in the UK?

The chair has won the Silver Award in the International Design Awards International Design Awards competition.
