Regency Sapphire Hybrid Mattress Twin

Feel ratings are on a numeric scale of 0 to 100, with the higher the number, the harder the feel of the mattress. In order to “score” each of our mattresses on this scale, we performed a series of firmness tests with a Cornell Tester to measure the firmness of each mattress. These ratings were converted to a 100-point scale by taking the ratio of each firmness rating to that of the highest reading. Using this method, we defined our hardest product, the Orthopedic Ultra Firm, as a 100. All other scores were calculated on a relative basis.

Durability ratings are on a numeric scale of 0 to 10 for comparison purposes and listed as “Short” to “Long”. Because the useful life of a mattress can vary significantly for individuals based on a number of different factors, we started by using an average lifetime of 8 – 12 years for a top of the line mattress as our baseline. We then estimated performance values for durability based on product performance and expectations. For example, more wire in an innerspring translates to a higher score. The use of a real working box springs would also translate into a higher score.

Support ratings are on a numeric scale of 0 to 10 for comparison purposes and listed as “Low” to “High”. The support scale is based on our line of innersprings and whether or not a mattress is used alone or with a box spring. We started with our top of the line mattress sets scoring a 10 based on product performance and expectations. The score drops through our line as the amount of wire decreases. Less wire equates to less support and the scores are set to reflect this.
