Best Short Queen RV Mattresses for Side Sleepers in 2025 (Under $300)
Stay Comfortable Even After Winter Storage — No More "Concrete" Mattresses!
If you store your RV uncovered or unheated during winter—especially in cold climates like the Pacific Northwest—you've probably experienced this: your once-comfy memory foam mattress comes out in spring feeling like a slab of concrete. ❄️
You're not alone. Thousands of weekend RVers face the same issue:
- You only use your RV 6–7 months a year.
- You sleep on your side and need soft-but-supportive cushioning.
- You don't want to spend $500+ on a mattress that sits unused half the year.
- And you definitely don't want to wrestle a 90-lb mattress through a tiny RV door.
The good news? You can find a comfortable, durable, budget-friendly short queen RV mattress that survives cold storage and fits your sleeping style—all under $300.
In this guide, we'll show you exactly which mattresses work best for side sleepers, cold climates, and real-world RV constraints—all under $300.
Short Queen vs. Standard Queen: Know Your RV Bed Size
Before you buy, measure your bed frame. Most RVs don't use standard queen sizes (60"x80"). Instead, they use:
- Short Queen: 60" x 75" (most common)
- Olympic Queen: 66" x 80" (in larger Class A or fifth wheels)
- Custom sizes: Some beds have cut corners, radius edges, or odd widths.
👉 Pro tip: If your current mattress is labeled "queen" but came with your RV, it's almost certainly a short queen. Double-check before ordering!

Detailed Buying Guide: What to Look for in an RV Mattress
Features to Prioritize
- Comfort Level: Choose between soft, medium, or firm based on your sleeping preferences and any back or joint issues.
- Material: Memory foam offers contouring support; latex is durable and hypoallergenic; innerspring provides bounce but may be heavier.
- Thickness: Thicker mattresses generally provide more comfort but may reduce headroom or storage space.
- Weight: Lightweight mattresses ease installation and reduce fuel consumption.
- Breathability: Look for ventilated or gel-infused foams to prevent overheating.
- Certifications: CertiPUR-US certification ensures foam is free from harmful chemicals.
Sizing Your RV Mattress
- Measure your RV bed frame precisely (length, width, and thickness).
- Consider standard RV sizes: short queen (60" x 75"), three-quarter (48" x 75"), or custom dimensions.
- Allow for slight compression but avoid mattresses that are too thick for your space.
- Check door and slide-out clearances for installation.
Budget Considerations
RV mattresses range from budget-friendly toppers ($80-$140) to premium full mattresses ($200-$500). Consider your usage frequency, comfort needs, and budget when making your choice.
