What Tim looks for when he cuts one open

From more than 1 million mattresses taken apart. These numbers predict how long a mattress lasts better than the brand name does.

  • Support foam: 1.8 lb per cubic foot or more. 2.0 or more is better. The stock mattresses that come in RVs usually run 1.2 to 1.5 lb, which is why they sag early.
  • Comfort foam: 3.0 lb or more. 4.0 to 5.0 holds its shape longest.
  • Coils: 14-gauge wire or thicker. Thinner 15 to 18-gauge coils lose their support sooner.
  • Separate layers, not one slab. A comfort layer over a firmer support base wears more evenly.
  • Ask for the densities. Most makers don’t publish them. A maker that tells you is usually one worth buying from.
