Handy, But Slightly Bulky to Carry On
It took a bit of time for me to get on a plane to try this.  I was pretty excited to use it to help the inevitable discomfort of being in a plane for 5-6 hours in a seat that is slightly cramped. First off, having this in my backpack takes up a fair amount of space.  Would it be worth it?  I soon discovered that attaching it to the seat in front of me was easier than I expected it to be. Your mileage may vary, but for the most part, I think this would work for most larger planes.<br /><br />The rest does what it says, and my feet no longer touched the floor, but lay suspended in a hammock a few inches off the ground.  This is comforting, but also leaves you a bit less mobile (the passenger next to me wanting to get out five times during our flight)so having to take your feet out and let someone get out takes more time of course.  Did it help?  Somewhat yes, so in that respect it is a success.  But the cost of it being the bulk and trouble of setting up knocks off a star.  It's really up to you to decide if it's worth it.  I only tried it on two flights, so I will update if anything changes as far as how it holds up over time.<br /><br />Build quality is alright.  It seems sturdy enough to last a bit of time, but that remains to be seen.  I found the effect of it more comforting on my return trip due to my feet being sore and elevated positioning helps with that.  Overall, I say give it a shot.
