Big office desk (Walkley S6)

Big office desk allegedly originally from IKEA. I got off Freecycle, it came with no instructions and I struggled to assemble correctly. It's served me well cobbled together with bits of dowel, but someone with more DIY skills could probably get it to be more stable. The sides/stand is chipboard and the top is pretty heavy solid wood. Dimensions are 160cm long 75cm wide 78 cm high. Comes with two wooden drawers, one of which I could fit, the other not due to reasons above. The varnish on the top is worn a bit but not in terrible nick.
