EasyJet allows passengers to pre-select seats by paying a fee during the booking process. Up Front and Extra Legroom seats are priced higher and come with the Speedy Boarding pass, allowing dedicated check-in and priority boarding.
On new versions of easyJet's A319, none of the seats, except for row one, recline. On older versions, all seats do recline. Beware the seats in the back of the plane are narrower than those in the front.
