When you use a cover for your Bubalou, there is a chance that your Bubalou will "suffocate" due to condensation. The couches are then no longer able to breathe. A consequence of this are prints and/or nasty (mold) stains. Because of the suffocation, these can no longer be removed; the 'weather' gets into the fabric and/or frame. Therefore, do not leave the furniture covered outside. Do not use a cover or other objects to cover the furniture. If you do opt for a cover, keep in mind that the warranty of your Bubalou will expire.
