Outdoor Seat Cushion Set 22 L 24 W 4 H in - Waterproof Patio

Our review of the Outdoor Seat Cushion Set finds it best for homeowners who want a thick, supportive replacement for deep seating patio furniture without fussing over delicate covers. The set includes a 22 in x 24 in x 4 in seat cushion and matching back cushion and the single biggest reason to consider these cushions is the combination of 35D high-resilience foam and a waterproof, UV-resistant cover that holds shape and color under regular outdoor use. Overall they suit conversation sets and chairs where comfort, durability, and easy maintenance matter.

Key Features

• Size and fit: The seat is 22 in by 24 in by 4 in with a matching back cushion, giving a thick profile that fills deep seating and reduces the need for extra padding.
• 35D density foam: High-resilience 35D foam provides visible support and rebound that should resist deformation for up to five years under normal use.
• Waterproof cover: Double-stitched, UV-coated fabric resists rain and fading, making cushions simple to wipe clean after spills and sun exposure.
• Thoughtful details: Hidden YKK zipper, piped edges, handle and straps plus a latex non-slip bottom help with positioning and everyday handling.
• Packaging note: Cushions can arrive creased from tight packing; allowing 48 hours to settle or brief dryer use will restore shape without a return.

Who It's For

These cushions are ideal for people with outdoor sofas and chair sets who need a substantial, comfortable pad that resists water and UV damage. The sturdy 4 in thickness and 35D foam make them a good match for conversation sets and deeper patio seats where long-term support and appearance matter.

They are less suited to buyers who need custom or exact-sized cushions beyond the stated dimensions, or to those who want very soft, plush seating rather than a firmer, supportive feel. Measure seat dimensions carefully before purchase to avoid a poor fit.

Pros & Cons

Our Verdict

For homeowners with standard deep seating patio furniture, this cushion set delivers reliable comfort, durable waterproof covers and solid long-term support thanks to 35D foam, making it good value for outdoor use.
