I have had the cheap plastic ones, i have had the picnic table type one and finally i found that the one called MAMMUT table and chairs from Ikea is the best. I can sit on it and it still feels sturdy(i even did when i was pregnant). They are great for little kids and great as they get older, my 7 year old niece still sits at it, it wipes clean and come in various colours. Its is a little bit expensive and its plastic but honestly i think it will last my kids forever. I wish i bought it in the first place.
