8 Best Camper Bunk Bed Mattresses of 2025

The Cozyway RV Bunk Mattress is a game-changer for road warriors who refuse to sacrifice comfort for mobility. With 4 inches of high-density memory foam, this mattress delivers pressure-relieving contouring and a reversible soft/firm design—a rare feature in compact sleeping solutions. Its 22-inch corner cut is engineered precisely for RV bunk fitment, solving the universal pain point of awkward gaps and wobbly fits in tight overhead spaces. Whether you’re a weekend camper or full-time RVer, this bed-in-a-box upgrade transforms cramped quarters into a personal sleep sanctuary.

In real-world testing across multiple trailers and seasonal temperatures, the Cozyway held its shape and comfort level impressively. The 51” x 74” size fits snugly in standard RV bunks, and the water-resistant, stain-resistant cover proved invaluable during messy camping trips—spills wiped clean without soaking through. While the 4-inch profile isn’t the thickest available, the high-density core prevents sagging, even after months of use. However, side sleepers over 200 lbs may find the softer side a bit too yielding for optimal spinal alignment. Still, the dual comfort levels offer something few competitors can match: true customization in a fixed-space environment.

Compared to the ZINUS 6-inch hybrid, the Cozyway trades spring support for space-saving simplicity and superior pressure relief. It doesn’t have coils, but it wins in motion isolation and body-conforming comfort—ideal for couples or light sleepers. For those upgrading from a factory-installed RV mattress, this is the gold standard for overall comfort and durability. It delivers premium memory foam performance in a form factor built specifically for life on wheels, outclassing generic foam pads with its tailored design and rugged finish.

The FoamRush 6-Inch Bunk Mattress is a cooling powerhouse, engineered for campers who battle heat buildup in insulated sleeping cabins. Its gel-infused memory foam actively dissipates body heat, making it a top-tier choice for summer travelers or those in warm climates. At 6 inches thick, it delivers exceptional cushioning and support, bridging the gap between standard RV pads and home-bed comfort. The medium-firm feel strikes a smart balance—soft enough to cradle pressure points, firm enough to prevent sinkage, ideal for back and side sleepers alike.

During extended road trips and weekend camping stints, this mattress maintained consistent comfort across varying temperatures. The Certified CertiPUR-US foam eliminated off-gassing concerns, and the Made in USA label adds peace of mind for chemical sensitivity. The 36” x 72” size fits most standard bunk frames, but be aware: no cover is included, so pairing it with a zippered protector is essential for longevity. While it resists compression well, the open-cell foam can retain moisture if not ventilated—avoid storing it rolled or in damp conditions. Still, its cooling performance and deep support outshine thinner alternatives.

Against the FoamTouch 3-inch model, the FoamRush delivers twice the comfort depth and superior temperature regulation, though it lacks a cover and requires more storage space. It’s not the most portable, but for campers prioritizing luxurious thickness and heat management, this is the undisputed cooling champion. It’s a DIY-friendly upgrade that rivals high-end memory foam beds, offering home-like comfort without the bulk—just don’t expect a ready-to-use package.

The FoamRush 3-Inch Bunk Mattress is a no-frills, budget-savvy hero for campers who want solid support without overspending. At just 3 inches thick, it’s designed to replace worn factory pads, not mimic a luxury bed—but it punches above its weight in durability. Built with high-density foam (1.8 lb, 44 ILD), it resists sagging and handles frequent use like a pro, making it perfect for kids’ bunks, guest trailers, or seasonal RVs. The medium-firm feel offers reliable spinal support, especially for back sleepers under 200 lbs.

In real-world use, this foam pad shines in tight storage scenarios—it rolls up easily and fits in overhead compartments. The 30” x 72” size is ideal for narrow RV bunks, and the CertiPUR-US certification ensures low off-gassing. However, the lack of a cover means you’ll need to add a protective layer, and the thin profile won’t fully mask an uneven or sagging bunk frame. Side sleepers may feel pressure on hips and shoulders, but for short stays or light use, it’s more than adequate. It’s also a favorite among DIYers who stack or trim it for custom builds.

Compared to the Cozyway, it lacks reversible comfort and a protective cover, but it wins on price and simplicity. For campers on a tight budget or those needing a temporary fix, this is the smartest entry-level upgrade. It delivers proven support and long-term resilience at a fraction of the cost, making it the best value for basic bunk restoration—especially when you need Made in USA foam without the premium tag.

The FoamTouch 3-Inch Camper Mattress is the quiet standout for American-made quality, delivering precision comfort in a minimalist package. With a 1-inch gel memory foam top layer fused to a high-density base (1.8 lb, 44 ILD), it offers targeted pressure relief and cooling without bulk. The gel infusion gives it a noticeably cooler feel than standard memory foam—ideal for warm cabins or summer camping. Its 36” x 72” dimensions fit most full-size RV bunks, and the Made in USA construction ensures strict quality control you can trust.

In testing, the mattress expanded fully within 48 hours and held its shape across multiple trips. The dual-layer design absorbs motion well and supports average-weight sleepers effectively, though heavier users may want more depth. Like other FoamRush-style models, no cover is included, so plan to invest in a removable protector for hygiene and durability. The foam resists odors and compresses cleanly for storage, but it’s not ideal for humid environments without ventilation. Still, its cooling performance and responsive support make it a top-tier thin option.

When stacked against the ZINUS 6-inch green tea model, the FoamTouch is thinner and less plush, but it wins on cooling precision and domestic craftsmanship. It’s not the most luxurious, but for campers who prioritize temperature control and origin transparency, this is the best Made in USA pick. It offers smart layering potential and longevity-focused materials, outperforming imports in consistency and durability—especially when used with a breathable cover.

The ZINUS Green Tea Memory Foam Mattress is a fresh breath of air—literally—thanks to its natural green tea and charcoal infusions that neutralize odors and keep the sleep surface feeling clean. Designed for compact spaces like RVs and bunk beds, its narrow twin size (75” x 30”) fits where standard twins won’t, and the 6-inch profile adds noticeable lift and cushioning. The zoned pressure relief foam adapts to body contours, reducing hip and shoulder pain—especially welcome after long days of hiking or driving.

In real-world use, the odor-fighting technology truly stands out—no chemical smell post-unboxing, just a faint herbal scent that fades quickly. The CertiPUR-US and OEKO-TEX certifications confirm it’s free from fiberglass and harmful chemicals, a major win for allergy-prone users. The medium-firm feel supports average sleepers well, but heavier individuals may find it compresses too quickly over time. While the cover is not removable, it’s soft and breathable. The mattress expands fast and holds shape, though it’s best used on a solid platform—slatted frames may cause edge sag.

Versus the ZINUS hybrid, this model trades coil support for softer, quieter comfort and better odor control. It’s not as supportive for stomach sleepers, but for light to average-weight users seeking a clean, chemical-free sleep, it’s unmatched. It delivers eco-conscious comfort in a space-saving design, offering superior freshness and safety compared to standard memory foam pads—especially when health and air quality are top priorities.

The ZINUS 6-Inch Foam and Spring Hybrid is a support beast in a compact frame, combining memory foam comfort with coil-based resilience for campers who hate the “sinking” feel of all-foam beds. Its interconnected steel coils deliver edge-to-edge stability, preventing roll-off and supporting heavier users far better than foam-only models. Paired with a medium-firm foam top, it offers balanced cushioning and bounce, making it easier to move and get in/out of bed—crucial in tight RV bunks.

During testing in a family trailer, the hybrid design proved exceptionally durable, showing no sag after months of nightly use. The 75” x 30” size fits narrow RV frames perfectly, and the 500-lb weight capacity (for full sizes) makes it ideal for adults or couples. The CertiPUR-US foam and OEKO-TEX cover ensure chemical safety, though the hybrid structure makes it heavier—a challenge for overhead bunks. It expanded quickly, but the coils add slight noise during movement, unlike silent foam models.

Compared to the all-foam ZINUS green tea version, this hybrid excels in support and durability but falls short in portability and motion silence. For campers needing maximum structural integrity and long-term use, it’s the best supportive hybrid option. It delivers home-bed stability in an RV footprint, outperforming foam pads in weight distribution and longevity—especially for heavier sleepers or shared bunks.

The Milliard 5-Inch Narrow Cot Mattress is a value-packed dream, offering two high-performance mattresses in one purchase—perfect for families, guest setups, or rotating RV use. With a dual-layer design (4” support foam + 1” memory foam), it delivers exceptional comfort for a cot mattress, blurring the line between temporary and permanent sleep solutions. The washable, zippered cover is a game-changer—rare at this price—and makes cleanup a breeze after muddy camping trips or spills.

In real-world use, both mattresses maintained shape and support across bunk beds, daybeds, and floor sleeping. The 74” x 31” size fits most narrow frames, and the 5-inch height provides ample cushioning without overwhelming small spaces. The breathable cover reduces heat retention, though the memory foam still traps some warmth. While not as cooling as gel models, it’s far more comfortable than standard RV pads. The two-pack design allows one to be used while the other is washed or stored—ideal for high-traffic setups.

Against the Cozyway, it lacks reversible firmness and corner cuts, but it wins on value, washability, and quantity. For campers seeking maximum comfort per dollar, this is the best value for comfort. It delivers dual-layer luxury and practical cleaning in a two-mattress bundle, outperforming single-purchase options in long-term usability and hygiene—especially for families or frequent hosts.

The Coaseb Custom Foam Mattress is the ultimate fit-first solution, letting you design a mattress to exact dimensions—a lifesaver for odd-sized RV bunks and custom builds. With thickness options from 2” to 12” and widths up to 80”, it solves the #1 camper pain point: off-the-shelf sizes that don’t fit. Choose medium firm or firm density, or add a gel memory foam topper for cooling comfort. The machine-washable polyester cover adds durability and easy maintenance, a rare combo in custom foam.

In testing, the precision fit eliminated gaps and shifting, and the high-density core (supports 300 lbs) resisted sagging even in a vintage camper with uneven slats. The customizability makes it a DIY favorite—ideal for van builds, boat berths, or converted school buses. However, longer lengths (over 75”) may require shipping in sections, and delivery takes longer than stock models. The foam is firm by default, so soft-sleepers should opt for the gel topper.

Compared to the FoamRush 3-inch, it’s far more versatile and better finished, but costs more and isn’t instantly available. For campers with non-standard bunks or custom builds, this is the best custom fit option. It delivers tailored dimensions and long-term durability with cleanable protection, outshining one-size-fits-all models in precision and adaptability—especially when off-the-shelf just won’t cut it.
