The Complete Guide to Caravan Mattresses: Sizes, Types & Installation Tips

The Complete Guide to Caravan Mattresses: Sizes, Types & Installation Tips

Three weeks into our first proper caravan holiday, my wife turned to me and said, "I'd rather sleep in the car." The irony wasn't lost on me, we'd spent months researching the perfect caravan, checking every feature and specification, yet somehow completely overlooked the one thing we'd use every single night: the mattress.

That uncomfortable revelation led me down a rabbit hole of caravan sleep solutions, and eventually to specialising in mobile comfort at The Foam People. After helping hundreds of caravan owners transform their mobile bedrooms, I've learned that getting caravan sleep right isn't just about comfort, it's about making your home-away-from-home actually feel like home.

If you're reading this while lying on a lumpy caravan mattress, wondering if there's a better way, I have good news: there absolutely is, and it's probably easier than you think.

Why Standard Mattresses Don't Work in Caravans

Before diving into solutions, it's worth understanding why your caravan probably came with a subpar mattress - and why simply buying a standard household mattress won't solve the problem.

Space Constraints and Odd Dimensions

Caravan manufacturers design for maximum space efficiency, not sleep comfort. This results in bed sizes that don't match standard UK mattress dimensions. You might have a space that's 1.9m long instead of the standard 2m, or 1.2m wide rather than 1.35m for a small double.

Weight Restrictions

Every kilogram matters in a caravan. Standard mattresses, particularly quality ones, can be surprisingly heavy. A standard double memory foam mattress might weigh 30-40kg, which is significant when you're watching payload limits.

Access and Manoeuvrability

Getting a full-size mattress through a caravan door and around tight corners can be physically impossible. Many caravan layouts require the mattress to bend, compress, or navigate spaces that rigid foam simply can't handle.

Storage Integration

Most caravan beds aren't just beds, they're storage areas with lift-up bases or drawers underneath. Standard mattresses often don't account for these mechanisms, leading to poor fit and functionality issues.

Climate Considerations

Caravans experience more extreme temperature fluctuations than houses. Condensation is a constant concern, and some mattress materials handle humidity better than others.

Understanding Caravan Mattress Sizes and Shapes

Caravan bed dimensions can seem like a foreign language, but understanding the basics helps enormously when choosing or ordering a replacement mattress.

Common Caravan Bed Sizes

Single/Fixed Single

  • Typically 1.8-1.9m x 0.7-0.8m
  • Found in children's areas or compact layouts
  • Often irregular shapes to maximize space

Caravan Small Double

  • Usually 1.8-1.9m x 1.1-1.2m
  • Most common size in smaller caravans
  • Significantly smaller than household small double

Caravan Double

  • Generally 1.9-2.0m x 1.2-1.35m
  • Standard in mid-size and larger caravans
  • May have cut corners or angled edges

Island Beds

  • 1.9-2.0m x 1.4-1.5m
  • Accessible from both sides
  • Often found in larger, more expensive caravans

Dinette Conversions

  • Highly variable sizes
  • Usually rectangular but can be L-shaped
  • Often require split mattresses for easy conversion

Non-Standard Shapes

This is where caravan mattresses get interesting (and challenging):

Cut Corners Many caravan mattresses have angled corners to accommodate furniture or door swings. These cuts can be 45-degree angles or custom curves.

Radius Corners Rounded corners are common, particularly in newer caravans with modern styling. Standard measurements plus corner radius specifications are essential.

Stepped Edges Some caravans have mattresses that step around wheel arches or storage compartments, creating L-shapes or other irregular forms.

Split Configurations Dinette beds often use split mattresses that separate for easier daily conversion. These need to fit together seamlessly when assembled.

Material Options: What Works Best in Caravans

Not all mattress materials are created equal, especially in the demanding caravan environment.

Memory Foam: The Versatile Champion

Memory foam works exceptionally well in caravans for several reasons:

Adaptability: Quality memory foam can compress significantly for transport through narrow doorways, then expand to full size.

Weight Efficiency: High-density memory foam provides excellent support at relatively low weight compared to spring systems.

Custom Shaping: Memory foam can be easily cut to accommodate unusual shapes and sizes without compromising structural integrity.

Motion Isolation: Important in small spaces where partner movement is more noticeable.

Temperature Considerations: Modern memory foams, particularly gel-infused varieties, handle temperature fluctuations better than early versions.

Latex: Natural Comfort with Durability

Natural latex offers several caravan-specific advantages:

Breathability: Superior airflow helps manage condensation and humidity issues.

Durability: High-quality latex can last 15+ years, even with regular setup/pack-down cycles.

Natural Properties: Naturally antimicrobial and dust mite resistant - important in confined spaces.

Responsiveness: More responsive than memory foam, good for restless sleepers.

Considerations: Higher cost and weight than memory foam, and some people are allergic to latex.

Hybrid Solutions: Best of Both Worlds

Hybrid mattresses combine foam comfort with spring support:

Pocket Springs with Foam Top: Provides traditional feel with modern comfort layers.

Reduced Weight: Fewer springs than household mattresses keep weight manageable.

Edge Support: Important for smaller beds where you use the full surface area.

Considerations: More complex construction can mean higher cost and potential for component failure.

What to Avoid in Caravans

Traditional Spring Mattresses: Usually too heavy and don't handle irregular shapes well.

Very Thick Mattresses: Anything over 20cm can interfere with storage mechanisms and bed conversion systems.

Non-Flexible Materials: Rigid foams that can't compress for transport or conform to irregular shapes.

Open-Cell Foams with Poor Moisture Resistance: Can develop mould issues in humid caravan environments.

Weight and Space Considerations

Getting the mathematics of caravan mattresses right is crucial for both legal compliance and practical functionality.

Calculating Weight Impact

A typical caravan might have a Maximum Technically Permissible Laden Mass (MTPLM) of 1,400kg. If you're replacing a 15kg factory mattress with a 35kg premium alternative, that's 20kg of your payload gone before you pack a single item.

Weight-Saving Strategies:

  • Choose high-density foam over low-density alternatives (better support per kg)
  • Consider split mattresses if a single piece would be excessively heavy
  • Opt for vacuum-compressed delivery when possible

Storage Integration

Many caravan owners discover too late that their new mattress interferes with under-bed storage:

Check Clearances: Measure not just the bed size but also the clearance when storage compartments are opened.

Hinged Bases: Ensure your mattress choice works with lift-up bed bases common in caravans.

Daily Conversion: If your bed converts for daytime use, factor in how the mattress needs to fold, split, or store.

Transportation Logistics

Getting your mattress to and into your caravan requires planning:

Delivery Options: Many caravan mattresses can be vacuum-compressed for easier transport and installation.

Installation Timing: Plan installation when your caravan is easily accessible - not when it's tucked away in tight storage.

Help Requirements: Larger mattresses may require two people for safe installation, especially in confined caravan spaces.

Installation and Fitting Guide

Proper installation ensures your investment performs as intended and lasts as long as possible.

Pre-Installation Preparation

Clean and Inspect the Base: Remove the old mattress and thoroughly clean the base. Check for any damage, sharp edges, or protruding screws that could damage your new mattress.

Measure Twice: Double-check your measurements against the new mattress dimensions. It's easier to address discrepancies before installation.

Plan the Route: Figure out how you'll get the mattress from delivery point to final position, considering doorways, corners, and obstacles.

Gather Tools: You might need basic tools for any final adjustments or for installing mattress protectors.

Step-by-Step Installation

Step 1: Access Preparation

  • Clear pathways from entry door to bedroom
  • Remove any obstacles or furniture that might impede access
  • If the mattress is vacuum-packed, position it as close to final location as possible before opening

Step 2: Positioning

  • If compressed, carefully cut packaging in the final position
  • Allow compressed mattresses 24-48 hours to fully expand
  • Check fit before proceeding with bedding

Step 3: Fine-Tuning

  • Ensure the mattress sits properly on the base without overhanging or gaps
  • Test any moving mechanisms (storage access, bed conversion) with the mattress in place
  • Make minor adjustments to positioning as needed

Step 4: Protection and Bedding

  • Install a mattress protector designed for caravan use
  • Choose bedding appropriate for caravan bed sizes
  • Test the complete setup before your first trip

Common Installation Challenges and Solutions

Mattress Too Thick for Storage Access: Solution: Consider a slightly thinner mattress or check if storage mechanisms can be adjusted.

Difficulty Maneuvering in Tight Spaces: Solution: Use vacuum compression or consider split mattresses for easier handling.

Gaps Around Irregular Shapes: Solution: High-quality custom cutting should eliminate this, but foam gap fillers can address minor issues.

Interference with Bed Conversion Mechanisms: Solution: Test thoroughly before first use and be prepared to make adjustments to either mattress position or mechanism settings.

Custom Solutions for Unique Layouts

Every caravan is different, and some require truly bespoke solutions.

When You Need Custom Manufacturing

Unusual Shapes: If your caravan has significant corner cuts, curves, or stepped edges, custom manufacturing ensures perfect fit.

Split Requirements: Dinette conversions or storage access needs might require precisely matched split sections.

Thickness Constraints: Very specific thickness requirements due to storage or conversion mechanisms.

Weight Restrictions: Extremely tight payload limits might require custom foam specifications.

  • Precise weight specifications help manage payload
  • Professional cutting ensures clean edges and durability

Maintenance for Mobile Living

Caravan mattresses face unique challenges that require specific maintenance approaches.

Daily and Weekly Care

Air Circulation: Allow mattresses to air when possible. In good weather, open all vents and windows to promote air circulation.

Moisture Management: Use moisture absorbers and ensure adequate ventilation. Condensation is a constant challenge in caravans.

Rotation: Rotate your mattress regularly, but be aware that custom shapes might only rotate in specific orientations.

Protection: Use quality mattress protectors that are waterproof but breathable.

Seasonal Maintenance

Deep Cleaning: At the start and end of each season, deep clean your mattress using appropriate methods for your mattress type.

Storage Preparation: If storing your caravan for extended periods, ensure the mattress is completely dry and consider using desiccants.

Inspection: Check for any damage, wear patterns, or developing issues that might worsen during storage.

Climate Challenges

Humidity Control: Use dehumidifiers or moisture absorbers, especially during shoulder seasons when heating creates condensation.

Temperature Extremes: Protect your caravan from extreme temperatures during storage to prevent material degradation.

Ventilation Strategy: Develop ventilation routines that manage moisture without compromising security.
