This is a listing for a 2 piece padded rail set for a hard sided waterbed. These are the Jumbo Krinkle rail caps and feature a hard frame that doesn’t warp or break. These have 2 inch foam and are the standard cap just more foam and they are Krinkled. They are 82.5-83 inches long to account for your headboard brackets. If you don’t have waterbed brackets we usually suggest putting them closer to the foot of the bed but you can center them equally also. These are built to order and usually ship FED EX or UPS in about a week.
