First, open all the tabs that you want to have up each time you open Chrome and make sure they are in the order you want them to be in.
Then click the hotdog menu (the three little lines) on the upper right hand corner of your browser window and choose settings.
Look for the "On startup" section. Select the option for "Open a specific page or set of pages" and then click the little blue link that says "Set pages".
At the bottom of the window that pops up, click the button that says "Use current pages". Then click "Save".
That's it! Now when you open up Chrome, all of your tabs will open just the way you want them to.
*Note - If you use a Mac, these pages will only be opened each time you re-launch Chrome and not each time you open a new set of windows.
