Customized mattress evaluation system

A method of providing a custom bedding product for an individual person comprising the steps of:

• inputing into a digital processor body type data containing weight and size information of the individual person;
• with the processor, evaluating body type data and calculating body type parameters for the individual person;
• correlating the body type parameters with bedding product evaluation data and determining bedding product parameters specifying the design of a bedding product for providing suitable pressure distribution and lumbar support for the individual person;
• the inputing of the body type data into the processor including:
• providing a stable support surface,
• providing a pressure sensor array on the top of the support surface, the array including a plurality of pressure sensors each adapted to measure pressure exerted against an area of the pad by a person reclining on the pad, and
• with the individual person reclining on, the pad, generating the body type data characteristic of the individual person;
• and
• wherein the bedding product and body type parameters include at least one limitation selected from the group consisting essentially of:
• the bedding product parameters include at least one box spring coefficient indicative of a suitable box spring for the individual person, at least one innerspring coefficient indicative of a suitable inner spring for the individual person, and at least two pad coefficients indicative of at least two suitable pad layers for the individual person.
• the bedding product parameters include at least one coefficient responsive to the total weight of the individual person and the bedding product providing step includes the step of determining a box spring component of the bedding product based on the at least one coefficient,
• the bedding product parameters include at least one coefficient responsive to the weight distribution area of support of the individual person and the bedding product providing step includes the step of determining an innerspring component of the bedding product on the at least one coefficient,
• the body type parameters include at least one coefficient responsive to a selected body width of the individual person and the bedding product providing step includes the step of determining a mattress fill component of the bedding product based on the at least one coefficient, and
• the body type parameters include at least one coefficient responsive to the lumbar support of the individual person and the bedding product providing step includes the step of determining a box spring component of the bedding product based on the at least one coefficient.

A system for customization design of a bedding product for an individual person, the system comprising:

• a support surface which provides a constant pressure of support;
• a pad positioned atop the support surface;
• a plurality of pressure sensors located on the pad, the pad and support surface adapted for the individual person to lie down thereon;
• a processor electrically coupled to the pressure sensors to record the pressure data detected by the respective pressure sensors;
• the processor being programmed with an evaluation algorithm to process the pressure data and produce a pressure profile for the individual person on the pad and in response to the pressure profile to calculate specific body shape parameters correlated to components of a bedding product providing suitable pressure distribution and lumbar support, the parameters including at least one box spring coefficient indicative of a suitable box spring for the individual person, at least one innerspring coefficient indicative of a suitable inner spring for the individual person, and at least two pad coefficients indicative of at least two suitable pad layers for the individual person.

The method of determining the support characteristics of a test mattress relative to a human weight and size profile, which method comprises:

• (a) measuring the weight distribution profiles of numerous different height, weight and shaped persons;
• (b) measuring and determining the optional deflection profile of those same persons for optimal support;
• (c) inputting the information of steps (a) and (b) into a computerized control;
• (d) locating a selected mattress in a test apparatus;
• (e) applying a weight profile load of a selected test profile person to pistons connected to independently movable pressure plates of the test apparatus, which pressure plates are positioned and sized on the mattress so as to mimic the shape of the selected person;
• (f) measuring the deflection of each pressure plate into the test mattress;
• and
• (g) comparing the measured deflection characteristics of the test mattress to the optional support deflections for the test profile person.
