The increase in the Office segment was led by recent introductions in complementary and ergonomic product categories. Net sales for the Studio segment were $80.8 million during the fourth quarter of 2015, an increase of 8.5%, or 11.7% on a constant currency basis, when compared with the fourth quarter of 2014.

Net sales for the Coverings segment were $27.4 million during the fourth quarter of 2015, a decrease of 1.3%, or 0.7% on a constant currency basis, when compared with the fourth quarter of 2014. Continued year-over-year growth in Spinneybeck | FilzFelt sales was offset by weakness at KnollTextiles and in the private aviation market of our Edelman leather business.
Gross profit for the fourth quarter of 2015 was $114.4 million, an increase of $11.5 million, or 11.2%, when compared with the fourth quarter of 2014. During the fourth quarter 2015, gross margin increased to 37.4% from 35.9% in the fourth quarter of 2014.

Adjusted gross profit for the fourth quarter of 2015 was $115.3 million, an increase of $12.4 million, or 12.1%, when compared with the fourth quarter of 2014. During the fourth quarter 2015, adjusted gross margin improved 180 basis points from 35.9% to 37.7%. This improvement was driven mainly by the Office segment, where business mix, foreign exchange rates, net price realization, operating efficiencies and improved fixed-cost absorption from higher volumes were all favorable.
Total operating expenses were $92.6 million, or 30.3% of net sales, compared to $82.9 million, or 28.9% of net sales, for the fourth quarter of 2014. Operating expenses in the fourth quarter of 2015 include $11.2 million of infrequent items. These items include a non-cash Edelman tradename impairment of $10.7 million, as well as restructuring charges of $0.5 million that are intended to streamline our corporate structure and improve future profitability. Operating expenses in the fourth quarter of 2014 included a pension settlement and other postretirement benefit curtailment of $6.5 million, restructuring charge of $0.7 million, and a $0.5 million charge for the remeasurement of the FilzFelt earn-out liability. Excluding these items, adjusted operating expenses were $81.5 million for the fourth quarter of 2015, compared to $75.2 million for the fourth quarter of 2014. The increase in adjusted operating expenses was related to higher commissions from increased sales volume as well as higher incentive compensation and profit sharing resulting from increased profitability.
