While itâ¤™s a privilege to have the latest interior design trends in your Philadelphia home, the same comfort can still be provided to you by your current interiors if you maintain them well. Newly-bought or re-upholstered pieces of furniture will only look perfect at first, but in time its cushions will limp and its fabrics will tear, turning them into memories of yesterday. Upholstered furniture basically consists of four parts: the frame, the support, the fabric and the padding. The frames hold the entire piece together while the support system reinforces and abuts the frames to the foams and the fabrics. Common support systems include springs in couches and solid legs in kitchen chairs. Materials used for frames also vary on the design, from rustic wood to metal and plastic.
