The slats are held in place with the Streetlock® stainless steel comb system, which extends the lifespan of the benches considerably thanks to the ease of replacing the slats. The supports are made of hot-dip galvanised steel, powder coating is available on request. The Lean Standard Bench is also available in the sustainable material Bamboo Brown, made from bamboo fibres. The visible fibres give the smooth, hard surface a playful look in terms of colour and structure.
