Scunthorpe pair Scott Wiseman and Joe Anyon will join Chesterfield this summer.
Defender Wiseman and goalkeeper Anyon have both agreed two-year deals, the Spireites have announced.
Manager Gary Caldwell told Chesterfield's website: "Scott is a winner who can play in a number of positions, which is important when I consider how we are going to set up for different games.
"Joe also has experience of playing in big games. He's very capable with his hands and feet, which is very important for me because of the way I want to play."
Anyon played both games as Scunthorpe lost in the Sky Bet League One play-off semi-finals this season while Gibraltar international Wiseman featured 26 times during the Iron's campaign.
The duo join a Chesterfield side looking to bounce back from relegation to League Two.
