Adding Sidebar to ONLY one page

Hi there – I have removed the sidebar feature from most of the pages on the blog of a project I’m working on. However – one page (Lifestyle link) needs to have a sidebar.

The other pages are just HTML the full width of the template because each ‘sidebar’ is to be different, and I tried the Core Sidebars extension but it didn’t work. But we would like to have a sidebar on the Lifestyle page (which is the blog to display posts)

Here’s the link

Do I need to create a page template that includes the side bar then style the content DIV for this or is there an easier way – ?? Can I include the sidebar in the HTML on that page only? (like I did on the other pages) but it be dynamic to the Sidebar widgets?

I know it’s a weird question but this was a unique request to have different header and sidebars on each page.

thanks so much,
Kari
