If you feel like you need an activity once you're in the tub, this bath accessory helps you relax while using your smartphone. From Thanko, the Ofuro Demo Chotto Mottete (hold this for me in the bath) is an inflatable pillow with an extended arm you can use in the bathroom or lying in bed.
In addition to the 90 degree curved arm, the bath accessory consists of a head rest and a waterproof smartphone case that is even compatible with the iPhone 6. The case attaches to the rest with a velcro patch. The adjustable arm keeps your phone at the right distance in the right hand. The pillow can be used without the arm as well.
