A 362 mm seat build, layer by layer. Six components, and the two thickest ones decide how the sofa feels after three years.
What this site is
Sprung takes apart sofas, mattresses and chairs, writes down the densities, the wire gauges and the joint types, then explains what each number does to comfort and service life. No brand rankings, no affiliate links, no adjectives standing in for measurements.
Four long pieces cover the parts that decide whether a sofa is still comfortable at year five: the foam in the cushion, the geometry of the seat, the spring unit under a mattress, and the frame holding all of that together. Every figure below came off a tape measure, a set of scales or a manufacturer spec sheet, and the sources are named in each article.
Articles
Foam
Density is mass per cubic metre, hardness is a separate number, and a showroom that quotes neither is hiding a 21 kg cushion. Here is how to read the spec and how long each grade lasts.

Seating
A sofa advertised at 1100 mm deep leaves most adults perching on the front edge with no back contact. The numbers that matter are usable depth, seat height and back angle.

Springs
Three spring systems, three different feels, and one marketing habit: quoting a coil count for a king size bed, then printing the same figure on the single. Compare coils per square metre instead.

Frames
The frame outlives every other part of a sofa or fails inside two years, and the difference is visible in the corner. Four tests you can run in a showroom without tools.

Foam grades are checked by cutting a 100 mm cube from a cushion, weighing the cube on a 0.1 g kitchen scale and multiplying by 1000, which converts grams per litre into kilograms per cubic metre. Seat dimensions are taken with a 5 m tape, loaded and unloaded, because a cushion measured at 460 mm in the shop sits at 420 mm once an 80 kg adult lands on the cushion. Spring counts are recounted from an unzipped mattress panel rather than copied from a label.
Prices quoted across the site are Dubai retail in AED, checked during 2026, and prices move. Treat every AED figure as a rough order of magnitude, and treat every millimetre figure as exact.
