To ensure quality control, Lebeda periodically sends mattresses to a national technical center testing department. At Leggett & Platt Inc, Lebeda's mattresses are run through a series of vigorous tests to make sure they are of the highest quality and durability. Below are some of the tests that the mattresses endure.
SONAR MEASURING SYSTEM PROCEDURES
The
Sonar Measuring System provides an accurate method of measuring the actual
height and/or loss of loft in a set of bedding. The system utilizes an
Ocean Motion Sonar XR-1000 ultra sonic transceiver / receiver. One
transducer signals in the vertical plane for height measurements with a second
in the horizontal plane for transverse locations data. The unit is capable
of readings over a given distance at the operator's discretion. The
system's primary use is in determining height loss in sets of bedding, comparing
a new or virgin sample to a post tested state.
INDENTION/LOAD/DEFLECTION TEST MACHINE
The
Indention/Load/Deflection (ILD) Test Machine is essentially a
tensile/compression tester, specifically designed and built for Leggett & Platt,
Inc. Its primary function is to perform firmness evaluations on
innersprings, boxsprings, upholstered mattresses and bedding sets.
CORNELL TESTING MACHINE
The
Cornell Testing Machine subjects a set of bedding, or other samples to be tested
to a cyclic loading of which force may be set at one's discretion, of a dual
hemispheric plunger. Its loading is quite similar to those in actual life
of a set of bedding.
The Cornell Testing Machine is capable of accommodating up to a queen size set of bedding. The data retrieved is recorded on standardized forms and may be used as comparative analysis of samples tested.
JUGGERNAUT ROLLER (ROLLATOR)
The
Rollator Test Machine is capable of running ASTM Procedure F 1566 Standard Test
Method for Evaluation of Innerspring and Boxsprings, Section 7 - Durability
Test.
