The Mattress That Comes with a Winnebago

While Winnebago brand RVs offer unbeatable quality, the factory mattress most Winnebagos come stocked with may not live up to the same standard. While functional, these factory installed RV mattresses often sacrifice comfort for lightweight and compact design, showing more noticeable wear or loss of support over time when used for extended travel. As a result, many Winnebago owners upgrade their home away from home with an aftermarket RV mattress, like SleepDog®, to ensure they’re bringing long lasting comfort with them.

The SleepDog® Solution

Unlike many other mattresses, SleepDog® RV mattresses offer a combination of comfort, support, and longevity tailored specifically for RVs, travel trailers and camper vans. Here's what sets SleepDog® mattresses apart:

Advanced Support

SleepDog® RV mattresses are constructed with multiple layers of high-density foam to provide unmatched support, eliminate pressure points, and minimize motion transfer while on the road.

Find the Right Mattress for Your Winnebago Model

Upgrading with the correct mattress size for your Winnebago is essential for the safest and most comfortable travel accommodations. To make sure the replacement RV mattress fits securely without intruding on floor space or headroom, it is crucial to measure the platform on which the mattress will lie. Here are a few Winnebago RV models and their most common mattress sizes:


Winnebago Minnie Winnie

Winnebago Minnie Winnie

Minnie Winnies are a Class C model available in six different floor plans, most of them featuring a 60 inch by 75 inch RV queen size mattress or 60 inch by 80 inch standard queen size.

Winnebago Voyage

Winnebago Voyage

The Voyage Travel Trailer comes in eight floorplans, most of which come stocked with a standard queen size or standard king size mattress along with other, more custom-size sleeping arrangements for the rest of the family.

Winnebago Sunstar

Winnebago Sunstar

The Sunstar is a Class A motorhome available in four different floor plans. Depending on the year of your model, some floor plans accommodate either a 72 inch x 75 inch RV king size mattress or a 60 inch x 75 inch RV queen size mattress.

**Please note: When looking for a replacement mattress it is important to know the exact measurements of your sleeping area. While many RVs, motorhomes, camper vans and travel trailers accommodate standard and RV mattress sizes, the best and most accurate way to measure for your new mattress is to measure the width and length of your mattress platform or foundation.
