It seems like the idea of a selfie stick was first developed in Japan decades ago. All the same, the concept was too early to be accepted by people. The following picture was shot by my digital camera which was controlled by my smartphone via WiFi. It's my way of napping in my office.
When I take a nap, direct air from the air conditioner is uncomfortable. Likewise the electric heater warms a localized part of my body which faces the heater. It's also uncomfortable. Consequently, I figured out this way of napping. The seat heater of my car gave me a cue for this style. As you see, the heater is set behind my back.
This outdoor chair can be folded not to take up space and can be reclined, but I use it in the upright position to receive the heat to my back from the heater. You might see it tight, but it's really comfortable. The compact and light seat with electric heater costs only 3000 yen. It's really cost-effective.
selfie; a photograph you take of yourself, usually so that you can put it on a social networking site （ロングマン英和には載っておらず、ロングマン英英から）
All the same,,, それでも、、、
