Sleep System Performance Tests
With the heavy use to which hospitality sleep systems are subjected, it is important to predict how well a mattress and box spring will perform. In order to determine if sleep systems can withstand the rigors of hotel usage, as well as to truly evaluate the relative performance of competitive bedding products, hospitality sleep systems should be evaluated by four standard tests.
The tests listed below are endorsed by the American Society for Testing and Materials, created to ensure the uniformity of test results. Sleep systems should be tested as a complete unit (mattress and box spring together) and should meet or exceed the minimum requirements noted.
- Repetitive Impact Durability Test (Cornell) - This test was specifically designed to test mattresses for hotel use. It is used to evaluate mattress durability by measuring load deflection (measure of support capability) and surface indentations (dimples).
| After 100,000 cycles, support should decrease no more than 10% and total indentation should not exceed 1". |
- Load Deflection Analyzer - This instrument measures the force required to penetrate a product at any given distance. This provides an objective measure of the support properties of the product or product component.
| There should be no more than a 10% change in products from pre- vs. post-durability testing. |
- Impact Drop Tester - This repetitively drops a 175 lb. weight from a height of 7" to test box spring integrity and simulate the abuse that jumping on a mattress causes. Set or permanent deformation is measured at different drop sites.
No more than 1" of set or permanent deformation should be allowed at any
drop site. |
- ASTM Hexagonal Roller Test (Rollator) - This test uses a 240 lb. roller to predict product durability over extended usage.
| No more than 1" of set and no more than 1" of dimensional change should be allowed in the mattress or foundation. |
