Quick Answer
To install the Bolstr Spare Outer Cover, unzip the old cover, remove it, slide the new cover over the Bolstr Evolv Bed, align the headrest opening, and zip it closed. Ensure the cover is centered and the fabric is smooth to avoid bunching. The process takes about 5 minutes and requires no tools.

If you own a Bolstr Evolv Bed, having a spare outer cover is a smart way to keep your dog's sleeping area fresh and clean. The Bolstr Spare Outer Cover is designed to be easy to put on and take off, but a few tips can make the swap even smoother.
In this guide, we'll walk you through the installation process, highlight common mistakes to avoid, and explain how to achieve the best fit. Whether you're replacing a worn cover or just want a backup for laundry day, these steps will help you get it done right.
Before You Start
Before you begin, make sure you have the correct cover for your Bolstr bed size. The Bolstr Spare Outer Cover comes in different sizes to match the Bolstr Evolv Bed, so double-check the size label on the cover against your bed's dimensions. If you're unsure, measure your bed's length and width and compare them to the size chart on the product page.
It's also a good idea to wash the new cover before the first use. This removes any manufacturing residue and helps the fabric soften. Follow the care instructions on the label—most covers are machine washable on a gentle cycle and can be air-dried.
- Check the size label on the cover matches your Bolstr bed.
- Wash the new cover before first use to soften the fabric.
Removing the Old Cover
Start by removing any bedding or inserts from the Bolstr bed. If your bed has a removable inner cushion, take it out to make the cover removal easier. Locate the zipper on the underside or along the edge of the cover. Unzip it fully before attempting to pull the cover off.
Gently pull the cover away from the bed frame, working from one end to the other. Avoid yanking or tugging on the fabric, as this can strain the seams or zipper. If the cover feels stuck, check for any Velcro or straps that may still be attached.
- Unzip the cover completely before removal.
- Remove any inner cushions or inserts first.
Installing the New Cover
With the old cover off, lay the new cover flat and identify the headrest opening. Align the headrest opening with the corresponding part of the bed. Slide the cover over the bed, starting from the headrest end. Work the fabric over the corners, pulling it snugly but not too tight.
Once the cover is over the bed, zip it closed, making sure the zipper track is fully engaged. Smooth out any wrinkles or bunching by running your hands over the surface. The cover should fit like a second skin, with no loose areas that could trap your dog's paws.
- Align the headrest opening first.
- Zip slowly to ensure the zipper teeth align properly.
Common Mistakes to Avoid
One common mistake is zipping the cover without aligning the headrest opening, which can cause the cover to twist and bunch. Another is pulling the cover too tightly, which can strain the zipper or create uncomfortable pressure points for your dog.
Also, avoid using the cover before it's fully dry if you've washed it. A damp cover can stretch and lose its shape. Always air-dry completely before installation.
- Don't force the zipper—if it resists, check alignment.
- Avoid installing a damp cover.
Step-by-Step Installation Checklist
- Check size compatibility: Confirm the Bolstr Spare Outer Cover matches your Bolstr Evolv Bed size. Compare the size label with your bed's dimensions. Checkpoint: A properly sized cover will fit snugly without excess fabric.
- Remove the old cover: Unzip the existing cover completely and remove any inner cushions. Gently pull the cover off, working from one end to the other. Checkpoint: If the cover resists, check for hidden Velcro or straps.
- Align and slide on the new cover: Lay the new cover flat, align the headrest opening with the bed's headrest, and slide the cover over the bed. Smooth out wrinkles as you go. Checkpoint: The headrest opening should sit evenly, and the fabric should lie flat.
- Zip it closed: Zip the cover closed slowly, ensuring the zipper track is fully engaged. Smooth the fabric once more to remove any bunching. Final check: The zipper should glide without force, and the cover should fit like a second skin.
