We should have used it for a while first, then we may have understood it was best that way. Most veeberths need them but we ended up with more berth than we needed. It was a triple!.
But what we didn't realize, we had made it difficult to get in and out of and tough to make up at night. Worst, I cut down a high mahogany curb that was nicely dovetailed on the corners to lower to a cushion fiddle height.
Once we started using it without the filler, it got much easier to enter and exit.
Your step looks very helpful. Why isn't it higher, just curious?
