Frequently asked questions
What is a slide out RV mattress?
A slide out RV mattress is designed to fit the specific dimensions of an RV's slide out room, which extends outward when parked. These mattresses are typically thinner and lighter to accommodate the moving mechanism.
How thick should a slide out RV mattress be?
Most slide out RV mattresses are between 6 and 10 inches thick, with 8 inches being the most common. Thicker options may not fit if the slide out has clearance limits, so always measure your space.
Can I use a regular mattress in an RV slide out?
Regular mattresses are often too heavy and thick for slide outs, potentially causing mechanical issues. Custom RV mattresses are lighter and properly sized to prevent sagging and fit the slide out mechanism.
What certifications matter for RV mattresses?
CertiPUR-US ensures foam is durable, low-emission, and free from certain chemicals. OEKO-TEX Standard 100 certifies that textiles are tested for harmful substances. Both indicate safer materials for small spaces.
How do I choose the right firmness for an RV mattress?
Your choice depends on sleeping position: side sleepers prefer medium to soft, back sleepers medium-firm, and stomach sleepers firm. Personal comfort preferences and any pain issues also guide firmness selection.

The Brooklyn Bedding RV Titan stands out for its hybrid construction and cooling features, making it the top pick for slide outs. For budget buyers, the Zinus Memory Foam 8-Inch delivers surprising comfort at a low price. If you prioritize cooling, the LUCID Gel Memory Foam is a solid alternative.
