Without measuring them, I’d estimate the tablet retention clamps on either side are about .25” thick. We primarily used this product for a lengthy road trip so case removal wasn’t an issue, but if you need to use frequently for short trips removing a tablet from its case each time could be a headache. Significant summer temperatures have not seemed to impact the load bearing effectiveness of the swivel connection between the vehicle headrest connection and the tablet support structure – functions like a car’s interior rear view mirror adjustment (I haven’t bothered to remove them from the vehicle as they are unintrusive). Overall very happy with this product and satisfied with its value/price.
