Our extension seats are add-ons that allow you to convert your sofa or corner sofa into a chaise sofa or chaise corner sofa. When you purchase a chaise seat kit you are provided with the parts that replace the existing seat on the sofa with a new seat which incorporates the existing seat and also extends out in front of the sofa by the same depth as the current seat.


Our extension seat kits can be purchased for all of our sofa, corner sofa, sofa bed and corner sofa bed products. The only restriction on where an extension seat can go is that it can't be positioned on an armless end i.e. if it is the last seat on a sofa or corner sofa there must be an arm positioned next to it and for a corner sofa, if you decide to purchase two chaise seats, you need to be careful to ensure that when they are fitted they won't clash with each other.


With our chaise seats the rear half is supported by the frame of the sofa and the front half is supported by a movable stool base.


As with the rest of our products you can choose to customize our range of extensions seats by choosing from any one of our 75+ different fabric choices, adding two colors to the same extension seat, adding piping detail or selecting from a choice of wooden or steel feet.


The different sizes of extension seat that we offer have been designed to work well in conjunction with the different seat modules that we have.
