Footsak Extra/Replacement Inner

Happy Sak inners are made of sheeting fabric, hand-stitched with a zip and filled with our premium mixed density polyurethane foam chip.

Inners can be purchased with or without filling. 

The zip allows for foam to be easily added or removed according to how firm you like your Happy Sak. 

The colour of the inners vary, but there is no difference in quality or spec.
