FoamRush 5 in x 26 in x 26 in Cool Gel Memory Foam Cushion - Medium

In this review of the FoamRush 5 in x 26 in x 26 in Cool Gel Memory Foam Upholstery Square Cushion, the bottom line is clear: this is a practical, customizable replacement cushion for chairs and small sofas that prioritizes pressure relief and cooler surface comfort. It combines a ventilated gel memory foam layer and a high density support base to deliver a medium feel that suits everyday seating, DIY reupholstery, and wheelchair or dining chair replacements. The review focuses on construction, comfort and real-world fit for home projects.

Key Features

• Dual-layer construction: A gel-infused ventilated memory foam top layer paired with a high density foam base provides pressure relief while maintaining supportive structure for sitting.
• Cooling surface: The gel infusion and ventilated design help disperse body heat so the cushion feels cooler than traditional memory foam under normal use.
• Medium firm feel: The combination of slow-response memory foam and a firmer high density base gives a balanced medium firmness suitable for many seating needs.
• CertiPUR-US certified foam: Materials meet independent quality and emissions standards, offering reassurance about foam safety for home use.
• Customizable and easy to trim: The foam is straightforward to cut, stack or glue for DIY projects such as reupholstering chairs, stools, or making replacement cushions to fit odd sizes.
• Cut-to-order availability: Foamrush emphasizes made-to-order cuts, which helps get closer fits for replacements and restorations without excessive trimming at home.

Who It's For

This cushion is well suited to homeowners and hobbyists who need a sturdy replacement for dining chairs, piano stools, wheelchairs, or small sofa seats and who value a cooler memory foam surface with moderate sink. It also fits people restoring vintage furniture or making custom cushions for RVs, boats and patio seating where a medium firm profile and good support are needed.

People who prefer an ultra-soft sinking memory foam or need a very firm orthopedic medical cushion may want to look elsewhere. Also, buyers who want a finished cover included should note this product is foam only, intended for use with separate upholstery or covers.

Pros & Cons

Pros

• Comfortable pressure relief from the gel memory foam top without excessive sinking.
• Noticeably cooler surface compared with standard memory foam due to gel infusion and ventilation.
• Durable feel from the high density base with a compression rate suited for everyday seating.
• Easy to customize for DIY projects and precise replacements.

Cons

• Firmness is described as medium but some users may find it firmer than expected, so personal preference varies.
• Sold as foam only, so buyers must provide or make a cover for finished seating.
