7-Inch Bunk RV Mattress Replacement 34in x 75in - Cooling Gel Memory

In this review the FoamRush 7-Inch Bunk (34in x 75in) is examined as a practical mattress replacement for RVs, campers, and small beds. The bottom line: it is best for travelers and RV owners who need a moderate, supportive mattress that reduces heat buildup and improves sleep in compact spaces. The layered construction of ventilated gel memory foam over high density support foam delivers noticeable pressure relief and a firmer, stable feel, making it a sensible upgrade when a lightweight, customizable mattress is required.

Key Features

• Cooling gel memory foam: The top layer is infused with gel to help disperse body heat and create a cooler sleeping surface during extended use.
• Ventilated design: Perforations in the memory foam promote airflow so heat does not concentrate against the body during sleep.
• Support core: A high density support foam layer beneath the memory foam maintains a medium firm feel and prevents excessive sinkage.
• Customizable foam: The foam can be trimmed, sliced, stacked, or glued to fit nonstandard frames and odd RV or boat beds.
• Multipurpose use: The mattress works as a replacement for RVs, campers, trucks, and can be repurposed for cushions, toppers, or DIY projects.
• Made in USA components: Constructed to provide consistent quality and pressure relief for compact sleeping platforms.

Who It's For

This mattress is aimed at RV owners, van lifers, and truck campers who need a 34in x 75in replacement that balances pressure relief with firm support. It is also a good fit for anyone restoring a pull-down bed or building a custom sleeping platform where the ability to cut and shape foam is important.

Those who prefer a very soft, plush feel or require an included fitted cover should look elsewhere; the product ships without a cover and some buyers describe the firmness as firmer than expected. If you need a two-sided or zippered cover included, plan to add one separately.

Pros & Cons

Pros

• Comfortable pressure relief from the gel memory foam layer that reduces tossing and turning.
• Customizable size and thickness by trimming or stacking to match odd RV platforms.
• Cooling gel infusion and ventilation help limit heat buildup compared with solid memory foam.
• Good value for a purpose-built RV mattress replacement that is easy to unroll and position.

Cons

• Cover is not included, so buyers must provide or buy a separate encasement for protection and aesthetics.
• Firmness is mixed in user feedback; some may find the medium firm feel too firm for side sleeping without an added topper.
