The Highlife Topseats are pre-assembled slat modules made of FSC®-100% hardwood. The slats (2.4cm - 1” thick and interchanging 8 or 13cm - 3” or 5” wide) are mounted crosswise in the distinctive alternating narrow and wide Highlife pattern. The standard length of the module is 200cm - 79”, and four different widths are available. The slats are invisibly mounted in a Streetlock® comb. The total height of the topseat is 6cm - 2.3”. Topseat units are invisibly mounted on a base structure installed by a third party.
