Cat tree for declawed munchkin?

My munchkin kitty is only about 7 lbs and declawed (this happened prior to me adopting her).

I recently moved and have windows in my room that are a little higher up. I've been looking for a 50" cat tree she could use to look outside, but it looks like she would have trouble with all of them. Does anybody have some small declawed kitties that may not be able to climb very well, and cat trees that have worked?

I have a small nine year old munchkin kitty that I adopted as a kitten.  She is not declawed but has always had a hard time climbing things.  I have a smaller version of this kity condo that is sitting next to the windows in our den and bedroom. She uses this to climb on to the window sills.  The one in our bedroom is next to both our cat tree and the window.  She will use it once in a while to get on the lower level perch on the cat tree.  Hopefully someone else with declawed cats can provide some advice based on personal experience.

This is similar to my cat condo but it looks larger in the picture.

This one is smaller than 50", but I use this particular tree as a "connector" piece for a special needs cat I have.

Something like this might work too?

This tree looks like it might be easier to maneuver. You wouldn't have to put the top perch on.

That looks really nice!
