Double Cab or Crew Max?
If Double Cab, then yes. The under seat storage from earlier years fits in the 2014 perfect. Local parts guy told me it wouldn't fit, so I bet him a discount on it that it would. 15% off later, I win. It fits. So if you have a Double Cab, order away.
Also check out Du-Ha under seat storage. May be something you'd like better than the Toyota one.
