I find these tables to be quite sturdy for my purpose (showcasing my beautiful houseplant collection). The legs do not wobble at all. I have saved the monkey wrench in case it needs to be tightened after my next relocation/move. With that said, I do not recommend putting heavy or gigantic towering plants ( I believe the seller mentioned a weight limit in the description.) I have table sized houseplants and one 4 foot tall cornstalk plant that is lightweight.
I like these tables so much, because I can move them easily from room to room. I am a senior citizen with arthritis so this is important to me. I have adopted the smallest table as a place to set my morning coffee and toast in the morning while waking up (and still in bed).
Easy to put together overall with one important note: Since each table is a different height, I recommend matching up the legs with the picture provided or on this listing, before attaching (so you do not attach the wrong size to the wrong table.
