A 30 x 75-inch mattress can be a practical fit for an RV bunk, camper, or other narrow sleep space, but thickness and foam feel matter as much as the footprint. These three options range from a simple 3-inch foam replacement to thicker memory foam designs. Before choosing, measure your sleeping platform and check how much clearance you have above it.

hoggisleep Bunk Mattress: A Medium-Firm Six-Inch Foam Option
The hoggisleep is a 30 x 75-inch, 6-inch-thick mattress made for tight bunk spaces in RVs and campers. Its layered design pairs 2 inches of AquaSoft memory foam with a 4-inch high-density foam base. The brand describes the feel as medium firm, which may suit sleepers who want some pressure cushioning without choosing an especially plush mattress.
The foam layers serve different purposes: the top memory foam is intended to distribute pressure, while the denser base provides the mattress’s structure. At 6 inches thick, it offers more material than the 3-inch CRAURU, but it also takes up more vertical space. Measure carefully if your bunk has a low ceiling, safety rail, or limited clearance.
The company says the mattress is made in Mississippi, uses CertiPUR-US certified foam, and is backed by a 10-year limited warranty. Those details may appeal to shoppers looking for domestic manufacturing and a stated warranty, though you should read the listing and warranty terms for the full conditions. The product information also says the mattress meets home fire safety standards and motor vehicle flammability requirements.
Compared with the INEHM, the hoggisleep has a similar overall thickness and a clearly described two-layer foam layout. The supplied details do not mention a removable cover, so it may be less convenient to clean than the INEHM’s zip-off cover. It is a practical choice when you want a 6-inch profile and a medium-firm design, provided your bunk can accommodate the height.
Pros:
- Six-inch profile with memory foam over a high-density foam base
- Medium-firm feel is stated in the product description
- CertiPUR-US certified foam and a 10-year limited warranty are specified
- Made in the United States, according to the manufacturer
Cons:
- May be too thick for bunks with limited vertical clearance
- The supplied details do not specify a removable, washable cover
Verdict: Choose the hoggisleep if you want a 6-inch, medium-firm mattress with a layered foam build and can confirm that the added height fits your bunk.
CRAURU RV Bunk Mattress: A Simple Three-Inch Replacement
The CRAURU mattress measures 75 inches long, 30 inches wide, and 3 inches thick. Its low profile makes it worth considering when a taller mattress might interfere with a bunk rail, overhead space, or nearby structure. It is made with high-density foam and comes with a white knitted cover already on the mattress.
The product description calls the feel medium firm and says the foam is intended to support the back and hips while holding its shape. The cover is described as a breathable, skin-friendly knitted terry cloth. That offers a finished surface straight out of the box, though the supplied details do not say that the cover can be removed for washing.
This mattress ships compressed in a box. The manufacturer says to unroll it and allow about one to three days for it to regain its full shape. Plan for that expansion time before you need the bed. Its simple foam construction and thinner profile make it a different kind of option from the two 6-inch memory foam mattresses in this guide: it may be a better match for a tight space, but it provides less mattress depth.
Check the condition and dimensions of your existing bunk before ordering. A 3-inch replacement can work well when you need to preserve clearance, but it may not provide the same amount of cushioning as a thicker mattress. The description focuses on RVs, motorhomes, caravans, and truck campers, so it is best matched to a compact bunk setup.
Pros:
- Three-inch height can suit bunks with limited clearance
- Exact 30 x 75-inch dimensions are provided
- Comes with a white knitted cover already in place
- Medium-firm, high-density foam construction is specified
Cons:
- Thinner profile may offer less cushioning than a 6-inch mattress
- Needs time to expand after unboxing
Verdict: The CRAURU is the most straightforward pick for a 30 x 75-inch bunk where a low 3-inch profile matters more than extra mattress depth.
INEHM Gel Memory Foam Mattress: A Thicker Pick with a Removable Cover
The INEHM is a 6-inch mattress designed for a 30 x 75-inch RV bunk. It combines gel memory foam with high-density foam, and the product description says the design aims to relieve pressure and support different sleeping positions. A firm core is intended to help resist sagging, while a non-slip base is meant to reduce shifting on the move.
Its cover is a standout practical feature. The brand describes it as a full-encasement cover with a zipper, so it can be removed for washing. The listed cover uses a heavier cationic fabric on the sides. This may be useful in a bunk that sees regular use, where easier cover care can matter as much as the foam itself.
The product information says the foam is CertiPUR-US certified and describes the mattress as suitable for RVs, trucks, trailers, dorms, trundle beds, daybeds, and adjustable beds. It also states a 12-month test period and an expected usable life of 8–10 years. Treat the longevity figure as the manufacturer’s claim, not a guarantee; actual wear depends on use and care.
The supplied product data marks this item as unavailable, so check the listing before planning to buy it. If it can be ordered, compare its removable cover and non-slip base with the hoggisleep’s stated warranty and layered foam construction. Both are 6 inches thick, so bunk clearance remains important with either one.
Pros:
- Six-inch gel memory foam and high-density foam construction
- Removable zippered cover for washing
- Non-slip base is designed to help limit movement
- CertiPUR-US certification is specified
Cons:
- Listed as unavailable in the supplied product information; confirm current ordering status
- Six-inch height may not fit every bunk
Verdict: Consider the INEHM if its listing is available and you want a thicker foam mattress with a removable cover and non-slip base.
How to Choose a 30 x 75-Inch Mattress
Measure the sleeping platform, not just the old mattress
Measure the bunk’s usable length and width, including any raised edges or curved corners that could affect the fit. A mattress that is too large may bunch against the frame, while one that is too small can leave gaps. Confirm that the listed 30 x 75-inch size matches the space you have available.
Check the height and overhead clearance
Thickness affects both comfort and fit. The CRAURU is 3 inches thick, while the hoggisleep and INEHM are 6 inches thick. Measure from the bunk platform to the nearest rail, ceiling, or upper bunk. Leave enough room for the mattress to sit without blocking access or pressing into nearby structures.
Choose a foam feel that suits your needs
Foam type and firmness can affect how a mattress feels. The hoggisleep is described as medium firm, and the CRAURU is described as medium-firm high-density foam. The INEHM combines gel memory foam and high-density foam, but the supplied product details do not give it a specific firmness label. If firmness is important to you, check the listing for more detail before ordering.
Consider how you will use the bunk
A mattress used occasionally for trips may have different needs from one used every night. For regular use, consider the foam layers, cover care, and warranty details rather than choosing on size alone. The hoggisleep lists a 10-year limited warranty, and the INEHM has a removable cover. The CRAURU offers a simpler, thinner construction.
Look at cover care and setup
A zip-off cover can make cleaning more convenient. The INEHM’s product information specifies a removable cover; the other supplied descriptions do not state that their covers come off. Also plan for setup: the CRAURU is shipped compressed and may need one to three days to regain its shape, according to the product description. Check each listing for current unpacking and care instructions.
Review safety and warranty details
Certifications and warranty terms can help you compare products, but read the listing for the exact details and conditions. The hoggisleep and INEHM descriptions specify CertiPUR-US certified foam. The hoggisleep also lists a 10-year limited warranty, while the INEHM description states a 12-month test period. These are different types of assurances, so check what each one covers before deciding.
Frequently Asked Questions
Is a 30 x 75-inch mattress the same as a standard twin?
No. A 30 x 75-inch mattress is narrower and shorter than many standard twin mattresses. It is commonly used for compact RV and camper bunks, but measure your frame to confirm the fit rather than relying on a size label.
Which of these mattresses is the thinnest?
The CRAURU is 3 inches thick. The hoggisleep and INEHM are both 6 inches thick, so they need more vertical clearance.
Which option has a removable cover?
The INEHM product description specifies a full-encasement zippered cover that can be removed for washing. The supplied details for the hoggisleep and CRAURU do not specify removable covers.
Do these mattresses work in an RV bunk?
All three are described for RV or camper bunk use. Still, check your bunk’s exact dimensions, thickness limit, and shape before buying. A mattress can match the listed footprint and still be too tall for a particular setup.
How long should I let a compressed mattress expand?
The CRAURU description says to allow about one to three days for it to regain its full shape after unboxing. Follow the instructions included with whichever mattress you choose, since setup guidance may differ by product.
Which mattress is best for everyday use?
That depends on fit and care needs. The hoggisleep lists a limited warranty and a layered foam design, while the INEHM has a removable cover and a non-slip base. The CRAURU may suit a low-clearance bunk, but its 3-inch profile is thinner. Compare those trade-offs with how often the bed will be used.
Final Recommendation
For a 30 x 75-inch bunk with room for a thicker mattress, the hoggisleep is a balanced choice, with a stated medium-firm feel, two-layer foam design, and limited warranty. Choose the CRAURU if keeping the mattress height to 3 inches is the priority. The INEHM stands out for its removable cover and non-slip base, but check the listing’s availability before considering it. In every case, measure your bunk and confirm the mattress height will fit your space.
