Mass per cubic foot of polyurethane foam. Quality residential cushions use 1.8–2.5 lb density; high-end and commercial spec calls for 2.5+ lb density for long cushion life.
In Practice
At Extra Touch Upholstery, foam density is part of the standard vocabulary of every commission — discussed openly with clients during the specification phase and documented in the written scope before any work begins. Whether you are restoring a family heirloom, commissioning a new custom piece, or refreshing a Lake Tahoe estate, this is the level of detail you should expect from a serious atelier.
