Do you like to fly and sleep in "flat seats"?

The space beneath a seat is a space useless for the legs of the passenger seated here, but convenient for the passenger behind to put his/her feet in.

Stretching out so as to have feet level with head takes about over 6 feet or 70-s, 80-s inches, or more, depending on your size and incorporating the extra space to keep the clearance from your feet and over your head, plus the thickness of wall separating your feet from next head and your head from next feet.

And it costs a lot to fly in so much real estate. Therefore it is cheaper and more affordable to buy some 50 or 60 inches pitch - and accept that your feet are lower than your head, and beneath someone else�s **** or head.

So, would you like to have your seatpan tilt so as to be completely on an inclined straight line with the footrest extending beneath the next seat and the reclined seatback? The incline would have to be appreciable to allow for the height of your feet and the thickness of the headrest ahead. You would tend to slide off feet first and have to be supported on some form of footrest.

Or would you prefer to have your middle supported on something level or inclined opposite to your reclined seatback? So as to stop you from sliding down the bed? That is, a non-flat seat with tilted footrest and seatback, and seatpan in the middle giving support?

Any opinions?

Both. Let each passenger pick.

If fully flat is not possible, have a seat that can be both flat at an angle and shaped to provide butt support like an ordinary seat.

I travel UA C class on long hauls so I have not had the opportunity to use a flat seat but I will soon as I intend to try newer airline c class products from other airlines.

Cannot get on with flat seats that are not horizontal. Especially if they are quite hard, I just slide down. I put them into a mode which is less than full recline.

Actually I wish could velcro myself in... now there's an idea.
