Sofa and bed seems like a good place to play or work with a laptop, but since sofa and bed are soft. the ventilation hole on the laptop can be blocked, causing laptop to overheat and even damage to the processor. NEVER use an laptop cooler on a sofa, bed or soft surface UNATTENDED, this can make the fan on the laptop cooler to get stuck, when the fan are receiving power but not able to move, the fan will get hot. This can possibly create fire hazard. Especially u leave your laptop on with the laptop cooler. However, those better laptop cooler which the fan is fully covered should be safe to use.
If you want to use laptop on sofa or bed, make sure the ventilation hole is not being blocked. Use a laptop cooler which is fully covered. Such laptop cooler can dissipate heat from laptop and prevent ventilation hole bring blocked.
When I use my laptop on bed, I usually bring my cooler along ~
