Abstract
A ladder manufactured with steps that contain a foam rubber cushioning. The hard ladder step is notched out at a one inch depth at the front edge to insert and permanently glue the one and one half inch wide foam rubber cushion, covered in a waterproof fabric, and extending the foam rubber cushion out one half (1/2) inch further than the front edge of the hard step. The cushioned steps are then attached to the ladder frame. The ladder step cushioned with the foam rubber provides a soft edge to lean ones legs against while using the ladder. The foam rubber cushioned step can be built into any style ladder and ladders made of various materials. The use of a ladder manufactured with this cushioned step would help protect him or her from pain or injury caused from leaning their legs against a ladder step made of a hard substance.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
