Awarded standard rate pip to-day

Hi, At last my decision came to-day awarded standard rate pip for mobility & daily living! What a relief it is however I am going to ask for a mandatory reconsideration as I told them that I am living downstairs on the sofa as I cannot climb the stairs and they have not mentioned this (The stairs) in the decision makers reasoning although they have said " I agree an aid such as a step, grab rail and bath seat will assist and support you to wash and bathe" How can I achieve this if I cannot climb the stairs! They also stated that I said at my assessment that "I was unable to stand for long however the use of an aid such as perching stool would help" I never mentioned anything about a perching stool nor did the assessor mention a perching stool, I told them that I did not cook a meal as I can not stand for more than a few minutes because of the severe pain and that I had already had a fall at the cooker and scalded myself as my knees give way without warning, so I no longer cook because of the danger I could be in. I also told them that I have someone come in 7 days a week to cook an evening meal and that my daughter calls every day to help with my dressing and makes me a sandwich for me to have at lunch time....Your thoughts on how I should approach all these factors would be most helpful, not forgetting a big thank you for all your help so far!
