10 years of PH1: from hospitality to offices in retrospect

Ten years ago, the creative minds behind Prast/Hooft added an original element to the unique character of the Zuid As in Amsterdam with the PH1 Chair, fueled by the high demands of lunching professionals such as bankers, lawyers and consultants. The very first PH1 was developed by Lensvelt in close collaboration with Ronald Hooft for restaurant Gustavino. The design stood out for its robust look and open structure with tough upholstery and sturdy finish. The suede-like upholstery of rugged-looking leather was strikingly detailed with outward facing seams.

After its introduction at Gustavino, the PH1 Chair found its way to several prestigious projects. From cocktail bar Gin Sum Club in Haarlem, designed by Claire Ansems (Defining Spaces), to the modern lounge space of Urban Industrial, where the PH1 Chair was used in its original raw leather version by Heyligers Architects. PH1 bar stools were installed in the interior of the government building Het Timmerhuis in The Hague; the interior was designed by O.M.A (Office for Metropolitan Architecture).

The New Generation PH1: enhanced elegance and dynamics

During the new phase of development, the PH1 Chair & Barstool is now even more comfortable and the frame is equipped with a dynamic mechanism that allows height adjustment by means of a convenient, unobtrusive lever under the seat, guaranteed optimal seating comfort for every guest. The seat of the PH1 new generation is upholstered with an exclusive 3D material by the innovative textile house ByBorre, especially for Lensvelt.
This innovative 3D knit has a layered construction, with the outside (front of the fabric) a blend of wool for a natural feel and GRS (Global Recycled Standard) recycled nylon, designed using the OTW® spinning method, which makes the fabric more durable against pilling, wear and tear. The inside (back) is made of GRS recycled polyester, which adds to the overall durability of the product. Of course, the PH1 chair & barstool can also be custom upholstered to your own liking for any project.
