Moonstone Deluxe is a premium carpet underlay — the pad that goes between your subfloor and carpet, and has more impact on how the finished carpet feels and sounds than most people realize. At 10 lb density, this is the serious rebond foam, not the tissue-paper underlayment that shows up in builder installs and compresses flat within two years.

• 10 lb rebond foam density — significantly firmer and more resilient than standard 6–8 lb pads; holds its loft under repeated compression
• Proper density extends carpet life by preventing fibers from grinding against the subfloor with every step
• Reduces noise transmission between floors — a meaningful benefit in multi-story homes and condos

Pro Tip: The warranty on most residential carpet requires a minimum pad density — and 10 lb typically exceeds it, which is exactly what you want. A cheap pad voids carpet warranties faster than anything else, and it's also the reason good carpet wears out in three years instead of ten. Don't cheap out on the pad; it costs a fraction of the carpet and does more for longevity than anything else you can control.
