The slats of the Solid Linear Benches are mounted into Streetlock® combs, with a spacing of only 8 mm – 0.3”. A low Quattro Back with four Solid slats can be mounted on the 12-slat Solid Bench (more than 90 cm – 35” in width) in the middle. Alternatively, a rounded off version is available, the Soft Back, which has gentler contours and provides more comfortable back support. In look and feel, both backrests reflect the minimalist design of the Solid Bench series.
