Many new moms favor this type of chair over the much newer glider style chairs. It could be because it reminds them of their mom or grandma comforting them when they were young or maybe they prefer them just because of their classic good looks. Oak indoor rocking chairs also have the benefit of easy clean up which is critical in a nursery.
Another consideration is whether the seat will swivel and turn or not. This was an important key in my decision. A swiveling seat is much easier for the user. Having a swivel seat on a scooter chair allows you to pull up next to a counter and swivel so that you are closer to the surface then the wheels would allow you to go.
For instance, something like cedar will only need to be oiled about once a year. Some woods, especially the teak hardwood, requires almost no maintenance because it makes its own oils which function as well as, or better than, synthetic oils. The risk of over-oiling is the accumulation of unsightly black buildup.
