This 1 piece safety cradle bumper was the perfect answer to our concerns for a safe bumper. My daughter wanted a bumper that fit tightly around mattress leaving no gaps. My husband and son decided to surprise her with a cradle crafted just for her soon to arrive first baby! They asked me to take care of all the bedding. I was so delighted to find aBaby.com Co. Of all the bedding products I ordered, the bumper was my daughter's favorite. It fit perfectly under and around the 15 X 33 mattress and looks great! Also, because this product was made to order, it took a little longer to arrive than the sheets. The customer service dpt. was very attentive to the date I needed it, and worked with me to insure it's timely arrival. I am a very satisfied customer.
