I made this desk myself. I bought the solid oak panel from a place in Epping Forest that collected fallen trees.
Sanded and wax varnished it and added the adjustable legs on it.
Alot of time and love went into making it. Sad to let it go.
It’s 110 x 48-55cm Leg heights adjust between 70-110cm (may go higher, 110cm is what they are set at now) Set the height you want.
Whilst you can adjust the height to suit your needs, it takes a bit of time to adjust so you wouldn't want to be adjusting them every day.
You'd typically adjust to the height needed and leave as that for a while or more.
