Query: Odd design, disappointing

Overall, I was disappointed with the Stokke Sleepi Bumper. I purchased this (and paid a premium) to have the Stokke-brand accessory with the expectation it would complement my existing Stokke crib and mattress set. I can't imagine why, but the bumper didn't fit the Stokke mattress. The bumper has straps that must go under the mattress, but they're too short to allow the bumper to sit on top of the mattress. As a result, the bumper has to squeeze between the mattress and crib sides making it bunch up. In addition, the bumper is too short to tie on the top of the rails and it's a very soft material, so it slides down and bags on top of the mattress, providing no buffer for the crib rails. The color and fabric are both classic and lovely, but this bumper just doesn't function as well as others I've seen.
