Virgin spent $25 million designing new seats for economy and premium economy in an attempt to make them feel more like a La-Z-Boy. Some of the features as reported by Fast Company:

• Designers added a track that lets passengers slide the bottom cushion forward in recline mode, revealing extra foam hidden under the seat-back padding. The change also angles the cushion upward to move the center of gravity and better distribute body weight.
• Designers created an S-curved frame with adjustable back support. Press a button on the armrest, and an airbag inflates or deflates, gently altering the seat's contour and pushing snugly against your back.
• An adjustable headrest has been standard equipment in automobiles for eons, but it hasn't been adopted by most airlines. Virgin's moves up and down 2.5 inches, offering neck support for a wide range of body types.
