The first test we utilized is a rollator test, where a heavy roller is cycled back and forth across the mattress surface to simulate anywhere from 10 to 20 years of use. Most mattresses are tested for 100,000 cycles (10 years of simulated use) using a 240 lb. roller. We tested Big Fig for 200,000 cycles (20 years of simulated use) with a 350 lb. roller.
This test is used to measure two important elements of mattress performance. The first is a change in mattress height. One of the worst problems in the mattress industry, especially for heavier people, is the loss of surface height (sagging, flattening, etc.) of the sleep surface. The second element is firmness. Over time, especially with heavier sleepers, mattresses start to feel softer and less supportive as the foam cushioning layers degrade.
In terms of mattress surface height, a loss of height of up to 1” over 100,000 cycles with a 240 lb. roller is within generally accepted industry standards. At 200,000 cycles with a 350 lb. roller, the Big Fig mattress lost only .158”.
Regarding firmness, a loss of firmness of up to 25% over 100,000 cycles is within generally accepted industry standards. The Big Fig mattress lost only 4.89% of its firmness over 200,000 cycles.
