What is the purpose of the air holes on the back of leather sofa cushions?
This is a question asked when someone discovers small holes on the back of a leather cushion and wants to check whether it is a finishing defect or a functional feature.
It is a passage that allows air inside the leather cushion to escape naturally the moment you sit down, helping to create a soft sitting sensation.
The moment you lean into a sofa, comfortable cushioning begins with the flow of air inside.
On the back of flat point's leather sofa cushions, there are air holes, which are small passages for air to flow in and out[1][2]. Unlike fabric, leather itself does not allow air to pass through easily, so if internal air does not escape in time when a person sits down, the cushion can inflate tautly and feel hard. The air holes naturally discharge internal air to the outside when weight is applied and draw it back in when standing up, creating leather's distinct stable cushioning sensation[3][4].
The zipper located on the back of the cushion is a finish included for the manufacturing process, not for taking out padding or replacing covers, so replacing the cover is not possible[5].
hmmm, a single small hole made on the unseen back turns the low-breathability nature of leather into a soft sitting sensation.
The specific size and number of cushion air holes for each sofa model have not yet been confirmed.
