The Poseidon Swing seat Arbour combines an arbour with a swing seat for a little added luxury and comfort. The traditional slatted bench-style seat is suspended from chains held by a strong wooden beam. The sides are half-clad with trellis, and the lower half with wooden slats. The roof is tongue and groove and offers some protection from the sun. Constructed from pressure-treated timber and should need no further treatment. If you do not like the natural colour or just want to add a splash of colour, then any exterior-grade wood treatment or preservative will be fine. It is a free-standing structure but can be placed against a wall or fence if you wish and can be secured to the ground using fence post spikes or post shoes (not supplied). Comes complete with full instructions and fixings needed to install. It is essential that the seat is placed on a level base. Nominal model sizes are based on the roof dimensions. Please refer to the exact measurements for the precise building dimensions.
