The room pictured on my site has an eclectic mix of furnishings and materials to add interest and textural differences. I definitely avoid matched sets of furniture when designing a room. Your two leather sofas may be able to work together in a family room, but without seeing them I can't say for sure. Since they are BOTH made of leather I am less likely to advise putting them together. Consider the other furnishings in your space and if there are opportunities to bring in patterns and textures in other elements so the room is not too full of just leather.

My brick red sofa is material....I have 2 other fabric chairs in the room...I just didn't know about 2 sofas one of which is material and the other is leather....THanks

Oh! Sorry for the confusion. If the sofas are not both leather then it sounds like they can live comfortably together in the same room with pillows and accessories to tie the room together. Have fun with your decorating!
