Cushion thickness is deck arithmetic, not a style choice: the maker builds the bare frame deck low or high knowing what will sit on it, and the cushion is the remainder to a comfortable finished seat. That is why a dining pad runs thin and deep seating runs thick — neither is an upgrade on the other.
- For a dining chairs or armchair
- 3–6 cm seat pad — slim enough that the shell still reads and knee room under a 74 cm table survives. A metal shell takes the slimmer end with a non-slip base; teak and woven frames carry 4–6 cm, with an optional tied back pad.
- Core
- Exposed pieces take an open-cell, fast-draining (reticulated) core: water passes straight through instead of pooling in the foam. A crowned profile sheds standing water by geometry. Neither makes a cushion waterproof — outdoor builds drain, they do not seal.
- Fabric
- Outdoor cloth earns its keep in the fibre. Solution-dyed yarn carries its pigment all the way through the fibre, so colour survives sun and scrubbing; surface-dyed cloth wears its colour off. Performance fabrics are water-resistant rather than waterproof, and mildew grows on dirt sitting on the cloth, not in the fibre itself — which is why the published care is washing, drying and standing a soaked cushion on edge to drain.
- Patterns & your own fabric
- Fabrics and patterns are fully specifiable — plains, stripes and prints, with repeat, direction and railroading captured in the brief so a pattern lands straight on every panel. Many pieces also accept customer’s own material (C.O.M.) — the brief asks rather than assumes.
Made to order through our supplier workshops — sized to this frame, in your chosen fabric, from a thin dining pad to a full deep-seating build.

- Rotomoulded polyethylene
- Rotational moulding transforms the plastic with a mould, heat and movement: high-density polyethylene particles melt in an oven and spread into the shape the mould was designed to, generally textured and Teflon-lined to give the finished piece its coarse surface.
- Cleaning
- Water and neutral soap. Never industrial products — glass cleaner among them.
