Trend analysis for Serta Cullman
Between 2019 and 2021, Serta Cullman's Total Case Rate improved from 7.7 to 4.8 recordable injuries per 100 full-time workers, a 38% decrease across 2 years of OSHA reporting.
The safest year on record was 2021, at a TCR of 4.8, while 2019 saw the highest rate, at 7.7, a spread of 2.9 points between the best and worst reporting years. That's a comparatively narrow spread, suggesting a fairly consistent safety record across the 3 years with a usable rate on file, rather than one outlier year skewing the multi-year average.
Summed across those 3 reporting years, Serta Cullman recorded 26 total injuries and illnesses, with no fatalities reported in any of those years. Readers comparing establishments should weigh the 3-year trend above alongside establishment size, since a larger workforce naturally accumulates more raw incidents even at a lower per-100-worker rate.

DART Rate, Transparent Calculation (2021)
What is the DART rate formula?
DART (Days Away, Restricted, or Transferred) is computed by OSHA as incidents × 200,000 ÷ hours worked. The 200,000-hour denominator equals roughly 100 full-time workers, which lets establishments of very different sizes be compared directly.
1 DART incidents × 200,000 ÷ 251,833 hours worked = 0.79 DART
Methodology: 29 CFR 1904, OSHA Form 300A recordkeeping
