In-pool sectionals let you build seating that matches the actual shape of your ledge instead of forcing a fixed set into a space it does not fit. Buy the pieces you need now, add more later, and reconfigure whenever you change the layout. Every module is molded from marine grade resin rated for permanent water contact.
Sketch your ledge and work in module widths rather than total inches. A common starting configuration is two middles with a corner and an endcap, which gives you an L that seats four without blocking the entry steps. Leave a gap where swimmers cross so the sectional never becomes a wall across the shelf.
Base and cushion are supplied together on the seating modules, and endcaps ship as base only. Cushions use fade resistant outdoor fabric and can be replaced on their own down the road, so the frames stay and only the soft goods refresh.
