Hello, Thank you for your review. Generally new rugs emit an odor. A rug that is made from polypropylene (olefin) may have some off gassing. It’s not toxic but if you are of concern (all synthetic material will have some smell) this odor is harmless, but airing out the rug in a well ventilated area generally solves the problem.
For the rug to lay flat, There are few suggestions you may want to consider to reduce this: • Back rolling/ Reverse rolling the rug (leave it back rolled for 48-72 hours)- place heavy furniture on rug while back rolled/ reverse rolled to keep it from unraveling • Use indoor rug/carpet tape-tape down corners of the rug to secure and flatten the ends of your rug. • Use a rug pad to prevent slipping and sliding • Use a rug gripper for hardwood flooring • Vacuum the rug where the creases are located • Simply allow ample time for your rug or runner to settle *These creases/waves/bumps will normally flatten-out on their own so in most cases you can simply allow ample time for your rug or runner to settle. If you’ve tried all of these suggestions, and this did not remove the creases or flatten the ends, I would strongly advise you to can get in touch with the vendor you purchased from for a return. Please be aware that vendors have their own return policy’s, please reach out to your vendor and see if you are able to return/exchange/replace/ this rug. Please remember these creases are not permanent!
