We bought a half dozen of these to replace all of our camping chairs this year.  They are pretty comfortable but they grab your lower hamstrings a little bit when you sit for a while and sometimes your feet can go numb.

We had a variety of chairs including two of the Coleman Max chairs which everyone would always take first because they were the sturdiest and most comfortable.  That's why we bought these.

Other than making under your rear end a little bit higher so it doesn't cut off the circulation to your lower legs the only suggestion I would make is adding a mesh elastic pocket to the back of the chair.

A large mesh pocket would be great for keeping all of your stuff like towels sneakers and a change of clothes out of the dirt or sand.

I am looking forward to getting several seasons of use out of these.

The cell phone holder and mesh pocket on the side are great features.  Could not hurt to have a second cup holder. Dexlue version?
