upholstery deck padding

Outer fabrics are typically polyester or acrylic. Inner fills commonly include foam, polyester fiber, or polypropylene; some cushions specify recycled polyester fill.

Outdoor cushions often advertise water-, weather-, fade- and stain-resistant fabrics. Some listings also note UV protection, mildew resistance, and resistance to mold or staining.

Most care instructions recommend spot cleaning or wiping and brushing off loose dirt. Some cushions advise hand washing or using mild soap and lukewarm water, then air drying.

High‑back Adirondack cushion sets in the results are described as about 3.9 inches thick for both the seat and back cushions.

Common thicknesses run roughly 2 to 4 inches. Listed options include 2", 2.5", 3", about 3.9", and 4".

Most cushions are secured with ties or string ties and adjustable back straps; some listings mention non‑slip ties or straps to reduce slipping.

Fill materials listed include 100% foam, 100% polyester fiber, 100% polyester, and 100% polypropylene. At least one description notes polyester fiber made from recycled plastic bottles.

Designs use tufting (including center or circle tacks) to hold filler in place; some listings explicitly state these features prevent shifting or clumping.
