 For instance, on several aircraft, Ryanair has installed non-reclining seats without seat pockets with the safety manuals stitched to the seat back instead.Even on airliners with reclining seats, some seats may have a restricted recline or no recline.Typically this will be the rear row of the cabin where a rear bulkhead blocks the recline, or seats immediately in front of the emergency exit where a reclined seat might restrict access to the emergency exit, creating a potential safety hazard.
