When my son was smaller we had folding storage ottomons that the lids flipped over to create a table. When he was about 2 1/2 we switched to a kids table with contact paper on top and slide it over to the couch when we need a coffee table.
Not sure where you live but Home sense has so many good upholstered ottoman options! I got a circular one that has storage to hold all of my bbs toys and the top is reversible - cushion one side and wood table top on the other side! We love it
We got this ottoman and it’s been 👌🏼. He can’t hurt himself on it and it also opens up for storage so ours is full of toys lol
