A water filled mattress including a top sheet of flexible material that is capable of having a bottom sheet of flexible material joined by heat sealing. The top and bottom sheet are joined at their peripheries and form a waterproof enclosure. The waterproof enclosure is capable of retaining an amount of water. The waterproof enclosure has a circumferential border with a front end and a rear end. A plurality of heat welds intermittently join the top sheet and the bottom sheet to form a plurality of seams. Each seam is linearly aligned along the waterproof enclosure. Each seam ends at an identical distance. A headrest is formed within the waterproof enclosure adjacent the seam ending. The mattress has a fill valve and a drain valve and an elongated tubular hose, having a first end connected to the fill valve, a second end connected to the drain valve, a bulb pump located between the first and second end of the hose, whereby upon the repeated squeezing of the bulb pump, the water contained in the enclosure is circulated between the front and rear portions of the mattress. Lastly, a lid that has a projection is positioned within a fill opening of the front end to capture the amount of water within the waterproof enclosure.
