40/4 designed by David Rowland

Problem Solver 404 David Rowland Stacking Chairs 840x1560 1

The 40/4 chair is one of the most successful contract chairs ever produce and was the first completely stackable chair ever invented.  The 40/4 was developed by American industrial designer David Rowland with practicality as the prime consideration.  He developed the chair over an eight year period and in 1963 was awarded a patent for his innovative design.

Determined to ensure that his chair would be as light and as easily stackable as possible, Rowland strove to reduce the structure to it’s barest elements. He succeeded in developing a comfortable chair for use in offices, conference rooms, auditoriums, and other large public spaces. Forty chairs can be stacked within a height of 4 feet (120 cm) giving the chair its iconic name. The frame of the chair is made of 7/16” solid steel rod and the seating surfaces are made from materials such as metal, polyamide, wood veneer, or upholstered in fabric or leather.

The 40/4 chair has been in continuous production since its introduction and has sold over 8 million units.  The design has received numerous awards including the Grand Prize at the 13th Triennale in Milan, Italy, 1964 when the chair was originally introduced.  

Problem Solver has proudly offered the 40/4 to our clients for over 25 years.

Arm Chairs

Building off of the solid frame of the Side Chair, Howe has produced the 40/4 Arm Chair. Available in wood veneer, polyamide and with upholstery, this chair has arm rests at just the right height. The sled base is made from the traditional 011mm steel rods, while 013mm steel rods are used for the rear legs and arms. You also have the options of having them in a chrome finish or powder-coated.

While there are the options for the finishes, the true customization comes with the arm rests. The arms are available with the polyamide, wood veneer, or upholstered finishes. They can be matched to the back and seat of the chair, or can have a completely different finish. Want a maple veneer with an upholstered arm rest? It can be done.

Hundreds of combinations are at your disposal.
