Brentford slipped to a first loss in 11 games
Lewis Grabban capitalised on poor defending from Daniel Bentley and Julian Jeanvier to score from close range in the first half.
With 10 minutes left Bentley should have done better when he came for and missed a corner, allowing Molla Wague to head home from six yards, before a late effort from Sergi Canos proved too little too late.
Brentford were left to rue a number of missed chances, with Neal Maupay twice bursting through the middle, but failing to get a shot on target.
Yoann Barbet also forced a good save from Costel Pantilimon with a 35-yard free kick, while Ollie Watkins fired across the edge of the six-yard box and Moses Odubajo almost nipped in at the back post but was foiled by Pantilimon.
Forest got their opener after a quarter of an hour when a smart back heel from Grabban saw him outfox the Bees defence before firing home.
Brentford forced two corners right on half-time, with great footwork from Said Benrahma setting up Maupay and Romaine Sawyers both seeing shots deflected.
Forest wasted two excellence chances early in the second half. First Diogo Goncalves rounded Bentley, only to see Konsa block his shot, then Grabban put the ball wide of Bentley and the goal from ten yards out.
While Sawyers hit the righ- hand post at one end, the Bees then conceded a penalty at the other after Grabban went down easily under a Jeanvier challenge.
Bentley kept the Bees in it, diving to his left to save the striker’s spot kick then bouncing back up to save Ben Watson’s follow up header.
But substitute Molla Wague wrapped up the points for Forest heading home a corner from six yards out with ten minutes remaining, while fellow substitute Canos pulled one back with a minute left, but it was too little too late.
Brentford (3-4-3): Bentley; Jeanvier, Konsa (sub Forss 90), Barbet; Dalsgaard, Mokotjo (sub McEachran 70), Sawyers, Odubajo, Benrahma (sub Canos 63), Watkins; Maupay
