That being said, you should absolutely put your idea up on Kickstarter.
You'll never know someone's true opinions about your product until you ask them to take out their credit card. And because you're so close to the work, you have no idea what's actually important to customers. So at the very least Kickstarter is a great way to get customer feedback. If it fails you can always launch again at no cost to you or your backers.
My biggest piece of advice is to keep the pledge tiers simple. We threw in other products because we couldn't offer a 'special edition' of the Classics. Bad idea. A special edition isn't necessary and we just made it confusing for potential backers.
We also priced the Classics way too high, but given our manufacturing situation at the time that's what we had to do. So the con is our project failed, but the silver lining is that people came out and told us what they wanted the price to be. It also brought a bunch of manufacturers and distributors directly to us.

Good luck!
Whether to put it on Kickstarter depends, I think, on what you're exactly trying to get from your funding, but I could see your bookshelf doing well. And is there a downside to trying with Kickstarter? Biggest one I can see is that your project doesn't get produce en masse, or, perhaps, that someone else sees it and copies it. But you can't live in fear of either of those. I'd say go for it.
P.S. I like it and my girlfriend likes it, we'd definitely buy a set if it's priced within the IKEA range.
+2 to Kickstarting it!
I'll follow up on this if I make any progress. M
