So basically a study desk would function like a table, however instead of food and symbel items the desk would have an inventory to put curiosities and another section to put things like quill pens, ink pots, parchment, abacus, magnifying glass etc... That would give a bonus to the lp gain the time to study and
slightly increase the attention of the person using it. On sitting down at the desk the items currently in your study slot would automatically move to the desk, to avoid any accidental loss of progress, and would return to your study slots(unless you exceeded you attention limit in which case some would be left behind) when you left the desk. You would be able to log out while studying and continue to study at the desk and gain its bonuses but the desk would be occupied at that point and no one else could use it until you logged back on and got out of the desk (like how beds work). The price of the desk should be fairly low but higher than a table maybe: wood, rope and bone glue. I can't really see how this could be exploited to much, although I haven't the experience to find all the loopholes in things
Hope this makes sense and thanks for reading
