Technical Advantages

Synchronized Hand-Crank Adjustment

Two hand-crank lifters are connected by a hexagonal shaft to provide a 120mm stepless adjustment range. The linked transmission helps both lifting points move in coordination, allowing schools to match furniture height with different student groups.

Stable Height Positioning

An impact-resistant PP lifting sleeve helps reduce shaking after adjustment. Anti-slip PP foot pads with leveling wheels provide additional floor adaptation during classroom arrangement, grade changes and campus renovation.

Materials For Daily Classroom Use

The 18mm E0 MDF desktop, PP injection-molded edging, food-grade PP seating components and 1.2mm powder-coated steel frame give procurement teams a clear basis for material comparison and project color coordination.

Applications

SY-302 is suited to primary and middle school classrooms, training centers, tutoring spaces and campus renovation projects where furniture height needs to serve changing student groups. The synchronized hand-crank system is particularly relevant when schools want adjustment flexibility without introducing several unrelated furniture designs.

For new installations, the adjustable range helps buyers plan furniture by grade level and student height. For existing campuses, SY-302 can support phased replacement of fixed-height sets while maintaining a coordinated appearance. Training spaces can also use the adjustment structure when one room serves different groups.

Final suitability depends on the selected size direction, student height distribution, classroom layout and required quantity. The adjustable structure should not be presented as a universal fit until the school confirms its size plan.

OEM / Service Support

Project and OEM orders can coordinate light gray, light blue, light green and CMYK color requirements while organizing the final size mix around the buyer’s grade-level plan.

Before sampling or quotation, confirm student height groups, classroom quantity, selected size mix, desktop and chair color, packing requirements, installation responsibility and delivery schedule. Sample review can cover adjustment operation, desktop finish, seat color and floor-contact details.

The current reference includes an MOQ of 200 sets and a 10-year warranty. Package dimensions, container loading, load capacity and installation scope require separate confirmation.
