Issues with contemporary sprung cushions
Contemporary sprung cushions have been marketed over the last decade as a superior concept however there are major issues regarding the effectiveness of using ‘spring pockets’ in the fabrication of seat cushion inserts.
Traditional sprung cushions were constructed using mid-gauge coil springs and hand sewn into a hessian case then encased with flock and fitted into a box piped seat cushion with sewing usually finished by hand stitching. Seat cushions constructed this way tend to stand the test of time as is evident by cushions still used in antique furniture.
However the fabrication of modern sprung cushion inserts utilise light-gauge coil springs encased in a series of thin polyester pockets which are normally referred to as ‘spring pockets’. These spring pockets are placed in the centre of the cushion inserts and sandwiched with polyurethane foam then usually encased with polyester fibre. With moderate to heavy use the spring pockets tend to distort with the springs often fracturing the casings. The result is a distorted and uncomfortable seat cushion and maybe a costly repair bill outside the warranty period.
The sales personnel promoting the “advantages” of sprung cushions usually infer by definition that the base is also sprung but most sprung cushions are on bases fitted with elastic webbing. The truth is that there is nothing wrong with a settee base correctly fitted with high quality elastic webbing. However a superior cushion insert can be effectively achieved by simply using premium quality polyurethane foam encased in polyester fibre and no spring pockets!
