Frequently Asked Questions
How can I tell whether my orthopedic bed needs a topper, a new foam insert, or a new cover?
Press and feel the foam. If the core compresses but springs back slightly, a 2–4" high-density topper can restore thickness. If the foam stays folded, torn, or feels crumbled, it needs a full replacement insert or a new bed. If only the fabric is torn or smelling, replacing the cover and adding a waterproof liner often solves the issue.
Will a topper stop my dog’s bed from smelling or leaking?
A topper alone won’t prevent leaks or odors. Use a waterproof internal liner beneath the topper to protect the foam from accidents and a washable external cover to remove odors. Gel-infused/open-cell foams tend to hold less odor than dense closed-cell foams.
How thick and dense should replacement foam be to restore support?
For most medium-to-large dogs, a minimum of 4" high-density foam (or a 2" memory layer over a 2" support base) provides reliable support. Look for high-density or gel-infused memory foam designed to resist flattening; density and construction determine longevity far more than just thickness.
Can I mix-and-match covers, liners and foam from different brands?
Yes, but measure carefully. Covers should fit snugly so toppers/inserts don't shift. Waterproof internal liners are largely universal but confirm zipper placement and dimensions to avoid bunching. For best performance, pair a high-density insert with a sturdy external cover and non-slip base.
