That is two different things. Take-off is not from wheels-up to 10,000 feet.
Once the wheels are up, take-off for the passengers is over. Put your seat back.
10,000 feet is when the critical phase of flight is over, approved electronics can be used, and non-essential conversations in the cock-pit can recommence. It has nothing to do with timing of putting your seat back.
