I'm not familiar with that brand of rug, but the store has a 'no questions asked' 10-day return policy, so that's a good sign. And that size rug should ship UPS, so that means shipping charges if you have to return it (and outbound as well) should be reasonable though it will be an oversize package.

Rugs are one of those things that you never know if they will work until you get them in your home, so try it!

Good luck.
