To solve such a problem that a caring load on a care giver is large because at-home care of a bedridden patient is executed on a bed and treatment of excretion in daily care is carried out by lifting the patient up or making the patient side-faced.

A cut-out part 2 and an opening part 3 are provided in a mattress body 1. When a cared person tells urination desire, the cut-out part 2 is removed and an inserting toilet 4 is easily set. After the urination, it is easy to remove the inserting toilet 4 and treating excretions. When the cut-out part 2 is fit in the opening part 3, the mattress can be used as a stationary mattress without causing uncomfortable feeling.
