Our seats are our most haunted furniture. We sit down and watch TV for a long time. Of course, sponges and fabrics wear out as much as we serve them. The sponges are dirtied and worn out due to the rubbing of the garbage cloths.
If you love your seats and do not think about changing them. I would like to give you an idea about the choice of sponges for your seats if you will only renew the sponges and fabrics of your old chair. Usually 28 or 32 dns sponges are used in the mattress part of the seats. 35, 36 dns, 45 h for you is suitable for 32 dns quality. There are hard soft group in one.
