Chesterfield managed just one decent shot on target as they succumbed to a goal in each half to a Blackpool side that had all but forgotten how to win.
Mark Cullen opened the scoring early on before Brad Potts turned defence into attack to wrap up the points and plunge Spireites down to 17th in the table.
Spireites face Crewe on Saturday knowing they must quickly stop their slump.
Do you think Chesterfield can turn it around or are they in for a long battle against relegation?
