Frame and seat build
The frame line should name the material: solid wood (and which), plywood (and its grade), engineered board, metal, or a combination. It may note how joints are made. The seat build line should say what supports the cushion: elastic webbing, sinuous (zig-zag) springs, pocket springs, or a combination. These parts are hidden once the piece is upholstered, so the sheet is the only record. If a seller cannot tell you what the frame is made of, treat that as an answer.
Foam and cushions
Foam should be named by type, such as high-resilience (HR) foam, standard polyurethane foam, memory foam or latex, and by density, stated as a number in kg/m³. Seat and back cushions often use different foams, and the sheet should list both. If fibre, feather or a fibre wrap sits over the foam, that should be listed too, because it changes feel and upkeep. Cushions sagging within months is a common complaint pattern among Indian buyers, and the foam line is where that risk is set.
Upholstery: type, code and colour
The upholstery line should say what the material is, such as fabric, velvet, bouclé, real leather, artificial composite leather or PU, and give the material's code and colour name from the swatch you chose. A code lets you check the delivered piece against the swatch and order matching material for repairs. For fabric, ask whether covers are removable. For leather-look materials, the sheet should state plainly whether the material is real hide or man-made.
Dimensions that matter
Overall width, depth and height tell you whether the piece fits the room and the delivery route. Seat height tells you how easy it is to sit down and stand up, which matters for older family members. Seat depth tells you whether shorter or taller people will sit comfortably with feet on the floor. Arm height and width affect both comfort and usable seat length. For recliners, the sheet should also give the depth when fully reclined and the clearance needed behind, so it does not hit the wall.
Mechanism, legs and finish
For recliners, the mechanism line should say manual or motorised, how many motors, and what functions they drive, such as footrest, backrest or headrest. From 1 October 2026, "Furniture with Electrically Motorized Parts" is listed by BIS under IS 302 (Part 1):2024 through the electrical appliances QCO (S.O. 1739(E), 6 April 2026), with later dates for small and micro enterprises. This applies to the finished product, so ask the seller about the product's certification status, not just the motor's. Check the current notification on bis.gov.in, as of September 2026. Legs should be named by material and finish, with height.
