We had a normal 140x200m slatted who mediated a rather unstable, sea state moderate-feeling! Has an inverted, was for the other not to think about falling asleep! This slatted frame, the very easy (approx 2 hrs., Man), was to assemble, is super-stable, it is well, calmly and firmly on each side, as actually everyone has their "own" bed base! A Super-good invention, value for money: very good! Delivery: Very quickly, well packaged, all the pieces in place, and even one or two spare parts for that matter! What more do you want? We are very satisfied and recommend this bed base with sturdy steel frame you!
