Outdoor Bench Cushions 42 x 18 in Thick Waterproof Porch Swing Cushion

In this review of the Outdoor Bench Cushions 42 x 18 in from Comcaver, the bottom line is simple: these cushions suit anyone who wants a thick, supportive, and truly waterproof pad for a porch swing or metal bench. The biggest reason to buy is the combination of solution-dyed fabric with TPU waterproof backing that keeps color vivid and liquids out for everyday outdoor use. The reviewer found the cushion noticeably thicker than many replacements, easy to clean, and secure on typical porch benches thanks to built-in ties.

Key Features

• UV FADESHIELD solution-dyed fabric: ensures the color is deeply ingrained in each fiber so the cushion resists fading and stays vibrant for up to 5 years of outdoor exposure.
• Total waterproof construction: a TPU coated layer and premium oxford fabric make the cover fully waterproof so spills and rain wipe off without soaking the filler.
• Non-slipping design: hidden zipper and two attached ties keep the cushion closed and anchored to a bench or swing to prevent shifting during use.
• 30D high resilience sponge: high-density filling provides solid support and prevents bottoming out for more comfortable seating over extended periods.
• Boxed piping edges: durable edge construction helps the cushion keep its rectangular shape and gives a neat finished look on benches and patio furniture.

Who It's For

This cushion is best for homeowners with metal or wooden porch benches and patio swings who want a thick, supportive seat that resists sun fading and everyday wet weather. It is especially useful for those who value easy maintenance and need a waterproof surface that wipes clean.

People who need a custom size not listed here, an ultra-soft indoor-only cushion, or a reversible style with distinct patterns may want to look elsewhere; this product focuses on durability, waterproofing, and colorfast outdoor performance rather than decorative reversibility.

Pros & Cons

Pros

• Very good colorfastness from solution-dyed fabric keeps the burgundy vibrant over years of sun exposure.
• Totally waterproof TPU coating prevents moisture from reaching the 30D sponge and makes cleaning simple.
• Thick, high-resilience filling offers better support and comfort than many original bench pads.
• Hidden zipper and ties give a tidy look and keep the cushion secured in place.

Cons

• Only one color and a set of fixed sizes are offered in a single-piece package, which may not suit all decorative preferences.
