Frequently Asked Questions
How do I tell if a bed's foam won't flatten?
Look for solid, high-density foam (specs often list density around 3+ lb). Descriptions that say 'solid' or 'therapeutic' foam, not shredded or glued layers, are better indicators. Heavy-duty covers and thicker foam (3–4 inches) also help preserve shape.
Are elevated cots better than foam beds for heavy sleepers?
They serve different needs. Cots are excellent for airflow, portability, and keeping pets off the floor, but they rely on mesh and frame strength rather than foam resilience. For prolonged pressure and joint support, a high-density foam mattress is usually better.
What if my dog chews the bed?
No consumer bed is fully chew-proof. For chewers, choose the toughest outer fabrics (ballistic nylon) and supervise or use deterrents and training. Covers can hide and protect foam, making replacements cheaper than an entire mattress.
