What value for money. Better quality than £189 ones I have seen and sat on. Very sturdy, robust and comfortable.  No need for instructions, you would need to pretty thick to get it wrong. The last part to fit is an end. I used wood glue with the dowels for extra stabilty, but that's just me over engineering. The 6 screws upwards into the seat need to fit into the pre-drilled holes in the seat and screwed in by the correct Phillips/Crosshead screwdriver to tighten. Allen key supplied but ensure you don't over-tighten the really long screws. ..Brilliant buy!!!!
