Summsun Outdoor Chair Cushions, Navy 18.5 x 16 x 2 in 2-Pack — Waterproof & Fade-Resistant

Summsun outdoor chair cushions are a set of two waterproof, fade-resistant seat pads sized 18.5 x 16 x 2 inches, designed to fit most patio and dining chairs with ties and a hidden zipper for removable covers.

These navy chair cushions combine resilient foam, weatherproof fabric, and practical attachment features so you get comfortable, low-maintenance seating for patios, porches, balconies, and poolside furniture. The covers are treated to resist fading and finished with a double-layer waterproof coating to keep the inner foam dry and extend the cushion life. Built to replace worn chair pads or refresh your outdoor seating, they balance support, durability, and easy upkeep.

How supportive and comfortable are these cushions for long outdoor use?

Each cushion is filled with 28D high-resilience foam that offers steady support and rebound, helping reduce pressure on the lower back and hips during extended sitting. At 2 inches thick, they provide noticeable comfort for dining and casual lounging without altering chair proportions.

• 28D high-resilience foam for firm but forgiving support
• 2-inch thickness for everyday outdoor seating comfort
• 18.5" x 16" sizing fits most standard patio and dining chairs

Will these cushions survive exposure to rain and sun?

The outer fabric uses a 250GSM polyester with a double-layer waterproof coating that helps prevent water from penetrating to the foam core, while a fade-resistant treatment preserves color vibrancy in outdoor conditions. These features work together to reduce weather damage and keep cushions looking fresh longer.

• Double-layer waterproof coating blocks moisture from reaching the foam
• Fade-resistant finish designed to maintain color up to three years
• Durable polyester resists routine outdoor wear and UV exposure

How do the cushions stay in place and how do you clean them?

Each cushion includes two adjustable ties that secure the pad to the chair frame to prevent slipping during use. A hidden zipper lets you remove the cover quickly for machine washing, simplifying maintenance without sacrificing a streamlined appearance.

• Two adjustable straps for a snug, non-slip fit
• Hidden zipper for easy removal and a neat look
• Machine-washable covers for low-effort cleaning

What seating situations and furniture types do these cushions suit?

These versatile cushions are designed for a wide range of outdoor seating — from wicker and rattan chairs to metal dining sets and poolside loungers. Offered in multi-packs, they make it simple to outfit a full patio set or replace only a couple of worn pads.

• Fits patio, lawn, dining, rattan, wicker, and balcony chairs
• Available in sets (2/4/6) for single or multiple-seat arrangements
• Compact size ideal for narrow or deep-seated chairs

Who is this for: Homeowners and renters who want an easy, durable way to refresh outdoor seating will appreciate Summsun's cushions. They suit anyone needing weather-ready seat pads that balance firm support and low-maintenance care — ideal for families, hosts who entertain outdoors, and compact-space dwellers upgrading chairs without replacing furniture.
