I bought 51" and regretted it, too small and not enough space for the chair and legs. The bigger one is definitely a good choice, I just won't return this one because the return process is boring, the product is heavy and it takes time to disassemble and repackage. The part where the wood is joint to form the "L" has a gap, could be better. The design won me over, but it was thin and low quality. It's worth it for the low cost.
