Knowing that a regular bed bug mattress encasement would not fit properly, finding one to fit a futon was difficult. Fortunately, iAllergy was one of the few vendors of futon encasements. Extensive research on encasements told me these important things: 1) It had to fit to work 2) The encasements might tear during "installation" 2) They are not returnable. After reviewing the Website and reading reviews, I selected IAllergy for my purchase. I could not be happier. The encasement was made of a soft, smooth and sturdy fabric with a covered zipper and it fit perfectly. There was no problem putting it on and no concern for tearing the fabric - even when the futon was folded. I highly recommend this product for those with bed bugs... or simply with allergies. This product earns five stars from a happy and satisfied customer.
