1. Zinus 6 Inch Green Tea Memory Foam Mattress: Best Overall
In our evaluation of RV Murphy bed mattresses, the Zinus 6 Inch Green Tea Memory Foam Mattress stands out for its balanced combination of comfort, fit, and affordability. Based on owner feedback and the spec sheets, the 6-inch thickness is ideal for fold-up beds, allowing the mattress to bend without damaging the foam. The green tea extract helps mitigate the off-gassing smell common in new foam mattresses, a plus for enclosed RV spaces. The CertiPUR-US certification ensures low VOC emissions and durability.
However, memory foam can sleep warm, which some users noted in hot climates. This mattress is not ideal for those who prefer a very firm feel or need a thicker mattress for heavy individuals. It is best for budget-conscious RVers seeking a reliable, medium-soft comfort level for occasional to frequent use.
- 6-inch profile fits most Murphy bed mechanisms without sagging
- Green tea infusion helps control odors in small RV spaces
- Pressure-relieving memory foam with good motion isolation
Pros: Excellent value for the price; CertiPUR-US certified for safety and emissions
Cons: May retain heat for some sleepers
2. Milliard 6 Inch Tri-Fold Mattress: Best Tri-Fold Design
The Milliard 6 Inch Tri-Fold Mattress is a versatile option for RV Murphy beds, especially where space is at a premium. We researched owner feedback and manufacturer specs to confirm that the tri-fold mechanism allows the mattress to be stored compactly when not in use, and it unfolds easily onto the bed frame. The included cover is a standout feature for cleanliness, as it can be removed and machine washed. The medium-firm density provides adequate support for most sleepers without being too hard.
Some owners reported that the fold lines become less pronounced over time but can still be felt, which may bother sensitive sleepers. This mattress is less suitable for those who prefer a plush feel or need a thicker mattress for heavier body weights. It excels as a secondary or occasional use mattress in campers.
- Tri-fold design makes storage and setup effortless in tight RV spaces
- Removable and machine-washable cover for easy cleaning
- Medium-firm feel with good support for back sleepers
Pros: Highly portable and easy to store; Washable cover is a practical feature for RV use
Cons: May develop creases at fold lines over time
3. Linenspa 6 Inch Innerspring Mattress: Best for Support
The Linenspa 6 Inch Innerspring Mattress is a solid choice for RVers who prioritize support and airflow. Our research shows that the fabric-encased coils provide consistent support and prevent sagging, while the quilted top adds comfort without exceeding the 6-inch height limit typical for Murphy beds. Owner feedback highlights that the mattress sleeps cooler than foam options, a plus in warm climates. The 10-year warranty is a sign of durability.
However, this mattress is heavier than foam models, which can make lifting and folding more difficult. It may not be ideal for those who need a lightweight option for frequent setup or for smaller RVs with weight limits. The innerspring design also transfers more motion than memory foam, so couples may notice disturbance.
- Innerspring coils provide strong edge support and airflow
- Quilted top adds a layer of cushioning without extra thickness
- 10-year warranty indicates manufacturer confidence in durability
Pros: Good airflow reduces heat retention; Strong edge support for sitting on the bed
Cons: Heavier than foam alternatives
4. Serta 6 Inch RV Mattress: Trusted Brand
Serta is a well-known name in bedding, and their 6 Inch RV Mattress brings that reputation to the camper market. Based on the spec sheet, the 1.8 lb density foam offers a firmer feel compared to many memory foam options, which some sleepers prefer for spinal alignment. The removable zippered cover is practical for cleaning, and the fiberglass-free construction addresses health concerns. Owner feedback generally praises the build quality.
On the downside, the firmness can be a drawback for side sleepers or those who like a plush surface. The mattress is also on the heavier side for its size. It is best for back and stomach sleepers who want a firm, durable mattress and are willing to pay a premium for the brand name.
- Serta brand reliability with RV-specific design
- Removable zippered cover for easy washing
- Fiberglass-free construction for safer sleep environment
Pros: Trusted brand with good customer support; Fiberglass-free is a safety plus
Cons: Firmer feel may not suit all sleepers
5. Casper Sleep Element Foam Mattress: Premium Pick
The Casper Sleep Element Foam Mattress brings a premium sleep experience to RV Murphy beds. In our evaluation, the three-layer construction (a supportive base, transition foam, and a breathable comfort layer) offers a good balance of contouring and support. The open-cell foam and breathable cover help mitigate heat retention better than standard memory foam. Owner feedback often highlights the comfort for side sleepers.
However, the higher price may not fit all budgets, and the 6-inch thickness may still feel too plush for some who prefer firmer support. This mattress is best for those who prioritize comfort over cost and are willing to invest in a better night’s sleep while camping.
- Three-layer design balances support and pressure relief
- Breathable cover and open-cell foam help regulate temperature
- CertiPUR-US certified for low emissions
Pros: Premium comfort with good pressure relief; Good temperature regulation for foam
Cons: Higher price point
6. Classic Brands 6 Inch Cool Gel Memory Foam Mattress: Best Cooling
The Classic Brands 6 Inch Cool Gel Memory Foam Mattress is designed to address the heat retention issues common with memory foam. Based on owner feedback and the spec sheet, the gel infusion and ventilated design do help keep the sleeping surface cooler than traditional memory foam. The medium-firm feel works well for most sleep positions, and motion isolation is excellent.
However, durability concerns have been noted, with some owners reporting sagging within the first year. This may not be ideal for full-time RV use. It is a decent budget-friendly option for occasional campers who sleep hot and want a cooler foam mattress.
- Gel infusion and ventilation channels reduce heat buildup
- Medium-firm feel with good motion isolation
- CertiPUR-US certified for safety and durability
Pros: Cooling gel helps hot sleepers; Good motion isolation for couples
Cons: Some reports of sagging after a few months
7. Milliard 4 Inch Tri-Fold Mattress: Ultra-Thin Option
The Milliard 4 Inch Tri-Fold Mattress is the thinnest option we evaluated, designed for Murphy beds with very limited clearance or for use as a temporary sleeping pad. Based on owner feedback, it is lightweight and folds into a compact size for storage. The 4-inch profile makes it one of the few options that can fit in tight folding mechanisms.
However, the thinness means less cushioning and support. Many owners report that it is not comfortable for long-term use, especially for side sleepers or heavier individuals. This mattress is best for occasional guests, children, or situations where a thicker mattress simply cannot fit. It should be skipped by anyone seeking a primary sleeping surface.
- Ultra-thin 4-inch profile fits tight Murphy bed clearances
- Lightweight and easy to move with built-in handle
- Tri-fold design for compact storage
Pros: Very thin, fits where 6-inch won't; Extremely portable
Cons: Limited support for heavier individuals
Frequently Asked Questions
What thickness is best for an RV Murphy bed mattress?
Most Murphy bed mechanisms require a mattress that is 6 inches or thinner to allow the bed to fold up properly. We recommend measuring your specific clearance before purchasing. A 6-inch foam mattress is the most common and offers a good balance of comfort and fit. Thinner options like 4 inches exist for tight spaces but sacrifice comfort.
Can I use a regular home mattress in an RV Murphy bed?
Regular home mattresses are usually too thick (10-12 inches) and will not fold up properly in a Murphy bed mechanism. They also tend to be heavier and may not fit the bed frame dimensions. We recommend using an RV-specific mattress that is 6 inches or less to ensure proper function and safety.
How do I clean an RV Murphy bed mattress?
Look for mattresses with removable, machine-washable covers for easiest cleaning. For foam mattresses without removable covers, spot clean with mild detergent and water, and allow to air dry completely. Using a mattress protector can help extend the life and keep it clean.
Are memory foam mattresses safe for RV use?
Yes, as long as they are CertiPUR-US certified, which ensures low VOC emissions and no harmful chemicals. Memory foam is popular for RV use due to its ability to conform to the folding mechanism. However, some people may be sensitive to the initial off-gassing smell, which typically dissipates within a few days.
Will a tri-fold mattress work in a Murphy bed?
Yes, tri-fold mattresses can work well in Murphy beds because they are designed to fold into three sections, making them easy to store and set up. They are also lightweight and portable. However, ensure the thickness (usually 4-6 inches) is compatible with your bed frame’s clearance.
Our Verdict
After comparing specifications and owner feedback, the Zinus 6 Inch Green Tea Memory Foam Mattress is our top pick for its excellent balance of comfort, fit, and value. For those who need a more portable solution, the Milliard 6 Inch Tri-Fold Mattress is a strong runner-up with its versatile design and washable cover.
