I'm about the same dimensions and and have taken my share of chairs back to pre-assembly. Furniture in general is pretty crap. Paradoxically I've found IKEA to be one of the most honest brands out there. I can normally tell by their look how sturdy they are. My mom has one pink plastic IKEA office chair that's been a trooper. It's developed a stress fracture where the back meets the seat that goes at least 70% through the material from me rocking it and the thing is. still. holding. up.
