Upholstery Tip #29: What is a tight seat?

When an upholstered chair doesn’t have a removable squab cushion, it’s known as a tight seat. The comfort comes from what’s hidden underneath, traditionally a base of coil springs, tied and built up to form a gentle curve or crown.

This subtle arch isn’t just for show. The outer springs are compressed more than the centre ones, giving the seat its shape and support. It’s a clever bit of design that balances structure with comfort, especially common in antique or classically upholstered chairs.

In more modern styles, a tight seat might be built using elasticated webbing or a wooden base, topped with foam or other stuffings. The defining feature isn’t what’s underneath, but how the top layer of fabric is finished, stretched and fixed directly to the frame, with no loose seat cushion on top.

So if you spot a firm, padded seat that doesn’t lift out, chances are you’re looking at a well-made tight seat.
