Frequently Asked Questions
When should I replace the foam in my senior dog’s bed?
Replace foam when you see deep permanent impressions that don’t rebound, when the dog shows new joint pain, or if the foam is crumbly or emits a persistent odor. Small soft spots can be remedied with a topper, but significant compression means the internal support has failed.
Do waterproof covers really extend foam life?
Yes. Waterproof (internal) liners prevent urine, drool and spills from reaching the foam, which otherwise causes degradation, odors and bacterial growth. Removable waterproof layers are the most effective single measure to protect internal foam.
Can a topper restore support on a flattened bed?
A high-density topper (2"–3") can restore comfort and pressure relief if the original foam is only moderately softened. However, if the core has deep, unrecoverable impressions or structural breakdown, a full foam replacement is the better long-term fix.
How often should I wash bed covers without damaging foam?
Wash removable covers as needed (every 2–6 weeks depending on accidents and shedding) using gentle cycles and mild detergent. Avoid machine-washing the foam; spot-clean and air-dry foam thoroughly if it gets wet. Having an extra cover prevents leaving foam exposed during washing.
Is gel-infused memory foam worth it for senior dogs?
Gel-infused foam helps with heat dissipation and usually indicates higher-quality, denser foam that resists flattening — both beneficial for senior dogs who need consistent support and may be less active.
