Direct Answer
Placing a sofa under a staircase in Indian duplex apartments and independent houses is possible with specific planning. The critical measurement: the lowest point of the stair soffit (underside of stairs) must provide minimum 85 cm headroom for a comfortably seated person. Standard sofa back height is 85-90 cm — ensure this clears the stair soffit at the front of the seating area. For tight clearances, a low-back sofa (70-75 cm) provides the seat comfort with reduced height that allows under-stair installation. A custom-sized compact sofa (140-160 cm wide) rather than a standard 200-240 cm 3-seater often works better proportionally in under-stair spaces. SOISU's pre-purchase measurement visit is valuable for confirming that a specific sofa configuration will work in an under-stair position.
Under-stair placement requires measuring the lowest point of stair soffit to verify minimum 85cm headroom for seated users. This is an essential consideration for Indian buyers. Conditions in India including seasonal humidity variation between 30-90% RH, temperatures from 10-45 degrees C, multi-generational household use, and proximity to Indian cooking all differ from European standards for which most premium furniture is originally designed.
Custom-sized compact sofas (140-160cm wide, reduced back height) are typically needed for under-stair positions. Practical application for Indian buyers: verify these points with your furniture supplier before purchase. Request supporting documentation, certifications, or material samples as appropriate. SOISU provides transparent material specifications on all products and welcomes comparison with any competing supplier.
