For folding sofa beds with built-in mattresses, 2-stage and 3-stage pull-out folding mechanisms are the classic structures compatible with traditional mainstream styles. Meanwhile, Italian-style rotating sofa beds, whose backrest and seat cushions rotate and open integrally with the bed frame, have become a new emerging market trend.
Compatible with most household standard sofa beds with built-in mattresses, this mechanism features a reasonable opening and closing stroke, smooth pull-out and folding movement, stable load-bearing performance and low failure rate. It is a long-established mainstream classic structure in the North American market, with strong universality for various conventional household sofa bed styles.
Adopting a three-section folding design for mattresses, it delivers superior sitting and sleeping comfort with a smaller installation depth and higher space utilization, suitable for a wider range of sofa bed styles. Equipped with a professional full spring tension system, it provides nearly the same excellent sleeping experience as the two-stage structure, even with a thinner mattress. It is a traditional mainstream structure widely adopted in the European market.
Featuring one-step rotational opening and closing, it supports instant operation with simple use steps and effectively prevents misoperation, boasting the lowest failure rate among all structures. It achieves better overall structural stability than two-stage and three-stage pull-out mechanisms. It has maintained the fastest market growth in the past decade and stands out as a highly competitive mainstream structure.
