Deep Seat Cushion Set 24 in x 24 in Cobalt Blue Texture

Our review of the Arden Outdoor Deep Seat Cushion Set finds it best for homeowners who want a durable, comfortable replacement for standard deep seat patio chairs and sofas. The biggest reason to buy is the combination of weather-proof, UV treated fabric and a firm-but-comfortable fill that holds shape - a practical choice for a busy patio where vibrant color and stain resistance matter. The set includes both a seat bottom and a pillow back sized to fit most deep seating and arrives compressed, so expect a short break-in to regain loft.

Key Features

• Exact fit: The bottom and back cushions are sized to fit most deep seat patio furniture, with the bottom at 24 in x 24 in x 5.75 in and the back at 24 in x 21 in x 6.5 in for consistent coverage.
• Weather resistance: UV treated polyester fabric helps the cushions resist fading, keeping the cobalt blue texture looking vibrant through sun exposure.
• Water and stain protection: Each cushion is treated with a PFAS-Free, C0 water and stain treatment to shed light moisture and everyday spills without harsh chemicals.
• Comfort and support: The seat bottom uses 100% superior polyester fill for a firmer cushion that aims to retain shape, while the back uses recycled polyfiber blowfill for softer support.
• Secure fit: The deep seat bottom includes two sets of ties to help anchor the cushion to chairs or sofas and reduce shifting during use.
• Made in the USA finishing: Patterns are designed in Michigan and the cushions are filled and finished in the USA, offering local design and manufacturing oversight.

Who It's For

These cushions are ideal for people who need a durable, colorfast upgrade for outdoor deep-seat furniture - homeowners with a patio, screened porch, or outdoor lounge who want a firm seat bottom and a plush back cushion in a bold cobalt blue texture. They suit those who prioritize low-maintenance fabrics with water and stain resistance and who appreciate American finished products and artist-designed patterns.

Those who prefer very plush, couch-like sinking cushions or require thick foam with structured edges for heavy daily use might look elsewhere; reviewers note mixed opinions on thickness and some users compare them to higher-end cushions for different comfort profiles.

Our Verdict

The Arden deep seat set is a practical, good-value choice for outdoor seating that needs colorfast, weather-resistant cushions with a firm seat and comfortable back. It is especially well suited to homeowners wanting low-maintenance fabric and secure ties on standard deep seating; buyers who need very thick, high-density foam should compare alternatives first.

Frequently Asked Questions

Will these cushions fit my deep seat patio sofa?
The bottom measures 24 in x 24 in and the back 24 in x 21 in, which fits most standard deep seat furniture but check your seat dimensions before ordering.

Do the cushions repel water?
Yes, the fabric has a PFAS-Free C0 water and stain treatment that helps resist light rain and spills but prolonged soaking is not recommended.

Why does the back cushion arrive flat?
It ships compressed; shake it vigorously and allow time for the recycled polyfiber blowfill to expand back to shape.
