While Comfort Works can cater to partial slipcover requests, this is not something we actively recommend due to the fact that partial orders may result in mismatched fabrics/colors.
For example, if you are ordering only the cushion slipcovers for an IKEA sofa, please note that Comfort Works' fabrics are privately sourced and stocked so these fabrics will most likely not match your original manufacturer's fabrics. A good way to find out would be to get fabric samples beforehand.
Another example would be if you were to be ordering only the frame slipcovers for a sofa you've previously had slipcovered by Comfort Works, we would still be unable to guarantee that fabric dye lot variations wouldn't occur between restocks.
However, if this is something you'd be willing to proceed with do send us an e-mail and we'll assist you with recalculating costs.
