TRP Aftermarket Parts has introduced high-density foam and innerspring mattresses for sleeper bunks in a variety of sizes.

The innerspring mattresses feature a high thread count and a three-layer quilted design that resists tearing, the company says.

At 7 inches thick, the innerspring mattress is designed to limit horizontal motion, which minimizes friction in the springs and reduces motion and noise. It also includes a straight cut foam topper over the top and bottom of the mattress.

The 5-inch thick foam mattress features high-density foam.

"By adding either a quality innerspring or foam mattress to their trucks, owner-operators and fleets can make their work environments more comfortable and productive," said Everett Seymoure, global manager for TRP.

Manufactured in North America, TRP mattresses meet or exceed U.S. Department of Transportation regulations for flammability resistance.

TRP's innerspring mattresses are available in 25-inch by 79-inch or 31-inch by 79-inch sizes. For larger requirements the mattress is available in 26-inch by 80-inch, 31-inch by 80-inch, 38-inch by 80-inch, 39-inch by 80-inch or 42-inch by 80-inch sizes.
