FoamRush 7-Inch Bunk RV Mattress Replacement 36 in x 72 in - Cooling

In this review of the FoamRush 7-Inch Bunk mattress replacement, the bottom line is simple: it is a practical, customizable gel memory foam option for RVs, campers, truck cabs and small guest beds that need pressure relief without excessive sink. The combination of a ventilated gel memory foam comfort layer and a high density support base delivers a noticeably cooler surface than typical memory foam and stable support for side and back sleepers in confined spaces, making it worth considering when replacing a 36 in x 72 in bunk mattress.

Key Features

• Dual-layer construction: A ventilated gel memory foam top over a high density support core provides targeted pressure relief on shoulders and hips while keeping the sleeper supported.
• Cooling gel infusion: Gel material in the memory foam helps disperse body heat so the mattress sleeps cooler than standard memory foam surfaces.
• Ventilated design: The top layer includes holes to improve airflow and reduce heat buildup for more comfortable nights in small, warm cabins.
• Easy to customize: The foam can be cut, sliced or glued, allowing trimming to fit odd RV spaces or stacking to increase thickness for a tailored sleep surface.
• Wide application: Suitable for RV bunks, camper trailers, truck sleepers and DIY projects where a replaceable, pressure-relieving foam pad is needed.
• Made in USA: Manufactured domestically, which some buyers prefer for quality and sourcing transparency.

Who It's For

The FoamRush 7-Inch Bunk is best for RV owners, camper trailer users and truck drivers who need a replaceable 36 in x 72 in mattress that balances pressure relief with support and will benefit from a cooler memory foam surface. It also fits DIYers restoring boat berths, vintage camper beds or creating custom cushions where trimming or layering foam is required.

It is less suitable for people seeking a plush, sinking memory foam feel or those who require an integrated cover or adjustable base compatibility without checking total system height; the product is sold without a cover and buyers should confirm combined mattress and foundation height before ordering.

Pros & Cons

Pros

• Comfortable medium-firm feel delivers good pressure relief while maintaining support for varied sleeping positions.
• Cooling gel and ventilation reduce heat retention compared with traditional memory foam pads.
• Customizable: easy to cut, layer or glue to fit unconventional spaces and DIY projects.

Cons

• Firmness opinions vary; some users find it noticeably firm, so sleepers preferring very soft mattresses may be disappointed.
• Cover is not included, so an additional purchase is required for a finished mattress surface and protection.
