We subjected a queen Big Fig mattress set (mattress and foundation) to the full range of industry standard tests. Tests included the Rollator Durability test, Cornell Firmness Retention and Surface Deformation test, and Impact test. Testing was performed by Leggett and Platt in their International Technical Center in Carthage, Missouri.
As you can see below, Big Fig performed exceptionally well on every test conducted. Continue reading for an explanation of the results, or click here to see the complete lab test report.
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.
This test is used to measure two important elements of mattress performance:
- 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.
- Firmness: Over time, especially with heavier sleepers, mattresses start to feel softer and less supportive as the foam cushioning layers degrade.
Most mattresses are tested for 100,000 cycles, simulating 10 years, using a 240 lb. roller. We tested Big Fig for 200,000 cycles, or 20 years simulated use, with a 350 lb. roller.
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 0.158”.
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.
This test uses a split ball form that cycles up and down to simulate someone sitting directly on the mattress.
As with the rollator test, the goal is to measure changes in surface height and firmness over the 100,000 cycles, simulating 10 years.
In terms of height, a loss of height of up to 1.75” for an innerspring mattress is within generally accepted industry standards. Big Fig lost only 0.3” in height in this test.
For firmness, softening of up to 15% is within acceptable industry standards. Big Fig lost 3.45% of its firmness during the test.
Finally, we subjected the mattress to an impact test to see how it holds up structurally when a heavy weight is dropped on it from increasingly higher drop points over the mattress. A 175 lb. weight is used, it is dropped from 2” up to 10” (in 2” increments) and this test is repeated in five different areas of the mattress (center, shoulder/calf, edge, end and corner).
This is an observational test and any visual damage and/or deformation is noted. At all heights and in all areas, Big Fig had “no notable damage or observations”.
