FAQ & Care

Two Sizes

For taller campers and those looking to stretch out, the standard Ursa is oversized with plenty of comfort. Combine with a second Ursa to create a queen size bed for two! When camping in the back of your SUV, Ursa Minor has the same maxed out comfort with a smaller footprint.

Fully Integrated

Built-in asymmetric zippers for seamless integration between each component prevents any shifting during the night. Connect two Ursa beds side by side to create a queen size bed.

Self-Inflating Base Pad

The four inch self-inflating Base Pad offers a comfortable sleeping surface that will elevate you from the cold and rocky ground. The reversible one-way valve allows for easy inflation and deflation, while also allowing you to fine-tune the firmness to your liking for personalized support and comfort.

At Home Comfort

Made from super soft yet durable materials that mimic the feel of your bedding at home, ditching traditional scratchy and noisy camp fabrics for a more comfortable experience.

Memory Foam Topper

The two inch memory foam Topper provides unmatched comfort and support no matter your sleeping position.The attached insulated hood blocks cold drafts and keeps your head warm throughout the night. A removable and machine-washable fitted sheet makes it easy to clean your bedding after each adventure.

Camp Comforter

Made with synthetic insulation, the comforter is rated for temperatures as low as 30 degrees and offers a perfect balance of warmth and breathability.

Customized Fit

The spacious built-in footbox is designed for improved heat retention, but is adaptable enough for warmer sleepers to kick their feet out from under the covers. Built-in shock cords at the head allow for a customized fit around the shoulders for improved heat retention and maximum comfort.

Travel Case

Provides a durable, easy to carry solution that keeps Ursa clean and safe and makes deploying and packing away easy. The Travel Case also features an additional pocket for small essentials.
