When searching for a quality camp chair, I kept going back and forth between these two.
First, I ordered the chair on the left by EA "Ever Advanced". I'm 5'1" and 165 lbs. and wanted a sturdy but easy to carry camp chair. The EA chair has a higher back and since I'm short, it definitely supported my head with room to spare when I leaned back. This chair advertises "lumbar support" and it's well made with a padded back and seat, but the reason why it gives you lumbar support is because it's a sling chair...your own weight molds the seating to your back. It has one cup holder, soda can sized, that is thickly insulated and one large open pocket on the right side for your phone and keys; no zipper closure. The pocket is sewn of both fabric and mesh. The armrests are padded and comfortable and they are height-adjustable. The chair doesn't have an attached strap but there is one on the carry bag. The chair weighs 8.5 lbs and supports up to 300 lbs.
I was a bit unhappy that the sling-style EA chair was a little difficult to get out of. My older knees sometimes need a firmer seat to help with standing.
So, I ordered the "Dual Lock" camp chair on the right by Kijaro. This chair locks open and the seat is very firm. Easy to rise out of. Again, my short height enabled my head to be supported when I leaned back. Taller folks won't have a head rest. The chair also locks when closed. Not tightly closed, but enough so that when I threw the chair's built-in strap over my shoulder in order to carry it without putting it back into its bag, the chair didn't fully open. This chair weighs 1 lb. heavier than the EA chair but honestly, I didn't notice the difference between the two when I had them over my shoulder. The Kijaro chair also supports up to 300 lbs.
The Kijaro chair's back has a slight lean-back angle to it; it's not a straight-backed chair. I might tuck a rolled hand towel behind my back if I feel the need for lumbar support.
The Kijaro chair has two cup holders made of plastic mesh. Not sure how sturdy they will prove to be. One is soda can-sized and the other one is slightly larger and would hold a no-handle-style, cylindrical travel coffee mug or a Starbucks frap drink cup. There is a very nice pocket to hold your gear on the right side of the chair; it's a little hard to see in the pic. It's sewn of fabric and mesh, and has a zippered main compartment as well as two open pockets on the outer face that are cell phone-sized. I really like the zippered pocket; a great idea for keys and other small items that you dare not lose. I also like the thick, reinforced binding along the edges of this chair and the pocket. Decorative as well as durable. Love the turquoise color!
Both camp chairs are well made. The EA chair has more padding; the Kijaro chair is a firmer sit. Both chairs were comfortable on the back of the thighs; no pinching. They both have comfy, padded arm supports and the seats were both wide enough that I had room to spare.
The EA chair has a carry bag made of softer nylon material and the end where the feet go is padded. The Kijaro chair's carry bag is made of a stiffer nylon material with no padding at the feet end of the bag. They close with locking drawstrings. Both carry bags have shoulder straps.
Because of all of the nice padding, the EA chair is more difficult to put into its bag. The Kijaro chair has less padding to fold up and also has that lock-closed feature which helps when putting it back into the carry bag.
Both chairs have non-breathable seating surfaces but the Kijaro chair has a mesh back for air circulation while the EA chair does not. Bring a terry towel to sit on to keep your fanny dry!
I hope that this comparison is helpful as you search for the perfect camp chair. Personally, the Kijaro chair wins over the EA chair.
