Frequently Asked Questions
Will a waterproof liner make my dog's bed hot?
Not necessarily. Some waterproof materials (like solid vinyl) can trap heat, but breathable liners such as TPU or well-designed laminated fabrics allow some vapor transfer. The best approach is a breathable waterproof inner liner paired with a soft, porous outer cover (microsuede or plush) to balance protection and airflow.
Can I wash the foam if it gets wet?
Avoid machine-washing memory foam. Instead, remove and wash outer covers and liners per their instructions; spot-clean any foam and allow it to air-dry fully in a shaded, ventilated area. Using a true waterproof inner liner prevents the foam from getting wet in the first place.
Are all waterproof liners the same quality?
No. Liners differ by material, seam construction and zipper design. TPU liners tend to be more breathable than basic vinyl. Reinforced seams and full zip closures offer better long-term protection than open or partial liners. Look for machine-washable, certified fabrics (like OEKO-TEX) if chemical safety and durability are priorities.
