Measure and record the dimensions of the room where the rug will be laid. This step may not necessary if you will be purchasing a small entryway rug.
Visit your local carpet and rug supplier and ask a salesperson about hypoallergenic options. Most stores will have a small portion of space dedicated to rugs made with natural, hypoallergenic fibers.
Select a rug that will complement the decor of your room. Most hypoallergenic rugs tend to be simple in appearance, but exciting patterns or colors can be found in some stores.
Compare the dimensions of your room with those of the available rugs. If the size you need is out of stock or backordered, you may be able to have it shipped to your home once it is available.
Purchase your rug online if there are no hypoallergenic options available at your local supplier. Be sure to verify correct dimensions before finalizing your purchase.
