Bed recommendations for a very large senior dog (Similiar to the coop dog bed, but no Big Barker ones)

I have a 13 year old lab who can no longer jump up to get into bed, and unfortunately Coop no longer sells dog beds. The one I bought years ago is amazing and he loves it, but I want 2 more for throughout the home.

I tried Big Barker recently and found the bed to be hard, and was looking for something with a lot more support.
