The move follows overwhelming feedback from passengers who want the reclining seats banned.
The new seats will mean more legroom, more storage space and will include a tablet holder – an aviation first, says the Luton-based airline.
Monarch marketing and customer service director Tim Williamson said: “Our new ergonomic seats have been designed with our customers’ needs in the forefront of our minds.
"The new non-reclining design gives our customers far more ‘living space’” than traditional seats, without the fear of the person in front impinging on their personal space.”
Passengers also want more storage space, he added.
“The new seats offer more flexibility than the traditional ‘pockets,’ using the concept of the bungee cord, and are large enough to hold water bottles, jackets and children’s toys," said Mr Williamson.
“The innovative tablet holder also enables our customers to create their own personal in-flight entertainment system."
Using modern design principles and lightweight materials, the new, non-reclining thinner design is similar to that used in the automotive industry.
The weight saving in the new design achieves significant savings on fuel and emissions.
