Though this is likely very old now this is the type of chair my grandmother rocked me in at age 2 in Seattle in 1950

 You don't see this style of rocking chair anymore from the 1930s and 1940s very much or at all anymore.

Something like this is really great for rocking young children to sleep that is soft for an adult to sit in while rocking children to sleep. The biggest problem would be pushing yourself up and out of a chair like this because you sink so deep into it amongst all the cushioning so you have to use the arms of the chair to push yourself out if you are older and getting up out of a chair is harder for you now. but everyone had one of these things into the 1950s especially in Seattle because a chair like this is very warm on your back too.
