Craftsmanship & Substance

Hand-Sewn Detail

Via Seating chairs are hand-sewn by highly-skilled sewers with a strong emphasis on attention to detail. The sewing team offers an apprenticeship program for those new to sewing and a tiered program for those of intermediate-level skills to higher. Only advanced-level sewers are approved to work on projects requiring the most extensive detail work. Quality checks and approval is signed off before a chair can advance onto the next stage in its build out.

No model shows this true craftmanship better than the Proform® chairs with their intricate, distinct stitch patterns.

Advanced Closed-Cell & Cold-Cured Foam Makeup

Every Proform® seat & back has 2 key elements in its foam makeup; it is “Closed-Cell” and “Cold Cured”. Closed-Cell refers to the fact that the foam has a smooth outer skin that is gentle on fabric. It does not rasp on the upholstery from the inside like traditional sheet foam. Further, the foam does not absorb moisture. The Closed-Cell nature protects the foam over-time and it does not break down. Cold-Cured refers to the consistency in size of the air cells within the foam. The foam of every Proform® seat & back is one single, contoured and resilient piece.

Expertly Tested Foam

Proform® seat & back foam faces a resistance factor test and measurement of density to assess the durability and quality of the foam. Density/volume weight gives an indication of the foam’s ability to resist weight and not “bottom out”. Good foam must provide resistance in direct proportion to the amount of pressure applied. This unit of measurement does not necessarily translate into hardness but rather the feeling of support you receive when you sit on the foam. The Proform® seat & back foam has an average density or volume of 3 pounds per cubic foot (48 kg/m3). Standard sheet or flat foam, by comparison, has a single volume weight between 1.9-2.25 pounds per cubic foot (30 to 40 kg/m3). The greater density of the Proform® seat & back makes it optimal for lasting at home working & learning use.
