Arden Outdoor Foam Deep Seat Cushion Set 24 x 24 Review (2026)
In-depth review of the Arden Outdoor Foam Deep Seat Cushion Set 24 x 24 in Tan Diamond Trellis: foam, fit, ties, and who should buy it.
Arden Selections Outdoor Foam Deep Seat Cushion Set 24 x 24, Tan Diamond Trellis
The pick for most people: a firm foam deep seat set with a trellis pattern that holds its shape and stays put with two sets of ties.
Our verdict
The Arden Outdoor Foam Deep Seat Cushion Set 24 x 24 in Tan Diamond Trellis is the best outdoor cushion for most buyers, because it gets the three things a deep seat cushion needs right: firm foam that holds its shape, a tall pillow back that fills the chair, and ties that keep the seat in place. It is not a soft fibre cushion, and buyers who want plush softness should look at the Pillow Perfect pads. For daily sitting on a deep seat chair, it is the pick.
What we like
- The high-density USA-made foam keeps the seat thick and supportive instead of flattening after a few weeks of sitting.
- The pillow back measures 24 inches wide by 21 inches long and 6.5 inches thick, so it fills a deep seat chair properly.
- Two sets of ties on the seat bottom hold the cushion in place on the chair, and the printed polyester fabric resists fading.
What to watch out for
- At 24 inches square it is too wide for standard dining chairs and smaller patio chairs, so measure the frame first.
- The foam arrives compressed and needs time to expand to its full thickness before first use.
- The firm feel suits buyers who like support, but it will feel hard to anyone expecting a soft fibre cushion.
Who it is for
Deep seat patio chairs, sofas, and couches, and anyone who wants a firm foam set that holds its shape through the season.
The foam is the point
The high-density USA-made foam is what sets this set apart from the fibre cushions. The seat bottom is 24 by 24 inches and 5.75 inches thick, and the pillow back is 24 by 21 inches and 6.5 inches thick, so the set fills a deep seat chair properly instead of leaving gaps at the sides. The foam keeps the seat thick through a season of daily sitting, where a fibre fill would go flat. The printed polyester fabric resists fading, and the tan diamond trellis pattern looks smarter than a plain solid.
What it cannot do
It cannot fit a small chair. At 24 inches square it is too wide for standard dining chairs and smaller patio chairs, so measure the frame first. It is also a firm cushion, and buyers who want a soft, sink-in feel will find it hard. The foam arrives compressed and needs time to expand to its full thickness, so do not judge it on the day it arrives.
How it stacks up
Against the Classic Accessories Montlake Lounge Chair Cushion Set 23 x 45 in Heather Fern, the Arden wins on cost and on the trellis pattern, while the Montlake wins on thickness at 5 inches and on the FadeSafe fabric. Against the Greendale Deep Seat Cushion Set in Azure, the Arden wins on foam support, while the Greendale wins on the reversible pattern. Against the Favoyard Outdoor Seat Cushion Set 19 x 19 in Beige, the Arden wins on size and support, while the Favoyard wins on cost and on the removable covers.

Questions, answered
Will it fit my deep seat chair?
Measure the seat width and depth first. The seat bottom is 24 by 24 inches, so the chair frame needs to be at least that wide and deep. If your chair is smaller, look at the Favoyard 19 by 19 inch set instead, or the Pillow Perfect 19 by 19 inch pads.
How long does the foam take to expand?
Allow time after unpacking. The foam arrives compressed for shipping and needs time to reach its full 5.75 inch thickness. Leave the set out flat in a ventilated room, and do not judge the comfort until it has fully expanded.
How do I clean it?
Spot clean the polyester cover with a damp cloth and a little mild soap, then let it dry fully before storing. Do not soak the foam, and bring the set in before heavy rain, since soaked foam dries slowly.
