SM New X Firm Mattress – Extra Firm

The SM New X Firm Mattress is designed for sleepers who prefer a very firm, highly supportive sleep surface. With minimal sink-in and a reinforced internal structure, it delivers a stable, supportive feel for customers who specifically want a firmer mattress. At the centre is a 20 cm Three-Zoned Pocket Spring system with foam encasement. The zoned pocket springs help distribute body weight across the mattress, while the foam-encased perimeter strengthens the edge and creates a more consistent sleeping surface from centre to edge. Above and below the spring unit are multiple supportive comfort layers, including HD hard foam, HD quilt foam, heat-treated cotton padding and Dacron foam. The mattress is finished with a high-class knitted fabric sleeping surface for a clean and comfortable finish. With its Extra Firm comfort level, reinforced foam layers and three-zoned pocket spring construction, the SM New X Firm is an excellent choice for sleepers who want strong underlying support and a noticeably firmer feel.
