The 21-year-old, who started his career with Arsenal, made 43 appearances last season and won the League One club's player of the year award.
Blackpool said they had already refused "several offers" for Bola, who turned down a "new, improved contract".
"There were other clubs interested, but he wanted to come here," said Boro head coach Jonathan Woodgate.
