3-Inch Bunk RV Mattress Replacement 30in x 72in - Medium Firm Support

In this review of the FoamRush 3-Inch Bunk mattress replacement, the bottom line is simple: it is a practical, durable high density foam option for anyone needing a thin replacement pad for an RV, camper, truck or bunk-style bed. The reviewer found it best suited to sleepers who want a balance of cushioning and firmness without sinking in, and for DIYers who may trim or layer foam to fit odd spaces. The CertiPUR-US certification and stated 44 ILD compression make the product especially appealing to those who want measured firmness and long-term durability.

Key Features

• High density foam: The foam is formulated to provide balanced support and durability for heavy use in RVs, campers and seats.
• 44 ILD compression: A measured compression rating gives a medium firm feel that resists excessive sink while offering pressure relief.
• Versatile sizing: The 30in x 72in bunk size fits many trailers, camper bunks and custom projects without needing a full mattress swap.
• Customizable: The foam is easy to trim, stack or glue so users can adjust thickness or shape for platform beds, futons or sleeper sofas.
• CertiPUR-US certified: Certification ensures the foam meets independent standards for safety and material quality compared with non-certified foam.

Who It's For

This 3-inch replacement is ideal for RV and camper owners, van lifers, and anyone who needs a thin, firm layer for a bunk or narrow platform bed. It also suits upholstery projects where a dense, resilient foam is required and trimming or layering will be used to fine tune comfort.

People who prefer a plush, thick mattress with deep contouring or those seeking a complete mattress replacement for nightly home bedroom use should look elsewhere; this product is optimized as a firm, space-conscious bunk or cushion solution rather than a full home mattress.

Pros & Cons

Pros

• Fits narrow bunks and campers and can be trimmed to custom shapes for a precise fit.
• Balanced medium firm feel backed by a 44 ILD compression that prevents excessive sinking.
• CertiPUR-US certification provides independent assurance of foam quality and safety.
• Durable high density construction intended for extended use over 7-12 years in heavy traffic situations.

Cons

• At 3 in thickness it may be too thin for users who need substantial cushioning for daily home mattress comfort.
• Cover not included, so buyers must provide or make their own removable cover for protection and cleaning.
