Deep Seating Cushion with Pillow Back 25 x 25 - Weather Resistant

In this review the RSH DECOR deep seating cushion set earns attention for anyone looking to refresh patio seating with a durable, comfortable option. The set includes a 25 x 25 x 5 in foam-filled seat cushion and a 25 x 21 in pillow back, and the single biggest reason to buy is the combination of a thick poly foam base and a soft, hypoallergenic pillow back that together deliver noticeable comfort and structure for outdoor chairs. It suits homeowners who want a sturdy replacement cushion that resists water and fading while still feeling plush.

Key Features

• Deep seat design: The 5 in thick foam seat provides solid support and improved comfort on deep outdoor chairs.
• Pillow back comfort: The sewn-seam back cushion is filled with hospitality-grade fiberfill for a plump, durable backrest that maintains shape.
• Water and fade resistance: Woven 100% spun polyester fabric offers water-resistance and colorfastness for outdoor exposure.
• Easy maintenance: Spot clean with mild soap and water and air dry to keep fabric looking fresh without complex care routines.
• Simple sizing guidance: Clear measurements help ensure a proper fit for squared seating; measure between arms and subtract 5 in from back height to match the top.

Who It's For

This cushion set is ideal for homeowners with standard deep outdoor chairs or patio seating who want a replaceable cushion that balances comfort, durability and low maintenance. It will appeal to people who prefer a defined foam base for support combined with a softer, hypoallergenic back pillow for lounging.

Those with curved or unusually shaped seating should look elsewhere, because the foam seat is designed for flat bases and may not fit properly in rounded frames. Also, buyers seeking machine-washable covers or down-filled luxury pillows should consider different options.

Pros & Cons

Pros

• Thick 5 in poly foam seat delivers consistent support and retains shape under regular use.
• Back pillow filled with hospitality-grade fiberfill stays plump and is hypoallergenic for sensitive users.
• Spun polyester fabric gives water-resistance and colorfastness for outdoor durability.
• Locally manufactured by a family-owned brand with straightforward care instructions.

Cons

• Foam seat may not conform to curved seating and can be a poor fit for non-rectangular chairs.
• Cover is spot-clean only, so heavy soiling requires more effort or removal for storage.
