I think the person who built mine must've ran out of spirit level bubbles... They're good quality solid wood tables, let down by poor workmanship. I don't think £50 is too cheap to warrant the tables being straight. The middle table top has been assembled in the factory so that it is not 'square' on the frame, so the overhang is different all the way around, so it's on an angle. I will enquire about a refund!
