CoreLift frame — technical data
Who this frame is for
You already have a tabletop. An existing one, one made to measure or one from your joiner — the frame adapts to it.
You are renovating a desk. Unscrew the top from the old base and fasten it to the sit-stand frame. The fixed desk becomes a sit-stand desk.
You are running a project. In an office refit the tabletops stay and only the frames are replaced. Less waste and a lower cost per workstation.
You are an architect or planner. DWG files and project pricing are available — write to sales@heka-interior.com.

Fitting your tabletop in three steps
1. Set the frame length. Extend the telescopic rails to the length of your tabletop (102–180 cm) and bolt them in place.
2. Fasten the tabletop. Place the frame on the upturned top, align it and screw through the holes in the rails and feet.
3. Fit the controller and cables. Screw the controller under the front edge of the top, connect both motors and the power supply, then turn the desk upright.
In the box: frame, memory height controller, power supply and fixings.

Frequently asked questions
Is the tabletop included?
No. You are buying the frame only — the lifting frame with two motors, a memory controller, a power supply and fixings. You supply the tabletop. If you want the complete desk with a top, choose the CoreLift sit-stand desk.
Which tabletops fit this frame?
The frame is telescopic and adjusts between 102 and 180 cm, so it fits tabletops of that length; longer tops will overhang the frame a little. The recommended depth is 60–90 cm. If you are not sure whether your top fits, send us the dimensions at sales@heka-interior.com and we will check.
Can I keep the tabletop from my old desk?
Yes, that is the most common reason to buy a frame. If the top is in good condition and within 102–180 cm, unscrew it from the old base and fasten it to the sit-stand frame. The fixed desk becomes a sit-stand desk.
How does assembly work?
In three steps: set the length of the telescopic frame, screw the frame to the upturned tabletop, then fit the controller under the front edge and connect the motors and the power supply. Instructions are included.
What is the warranty?
3 years. The warranty covers both motors, the lifting mechanism and material defects. We provide service and spare parts in Medvode also after the warranty expires.
Do you offer discounts for larger quantities or projects?
Yes. Volume discounts from 5 units up. For office refits where the existing tabletops stay we prepare a dedicated quote. Send an inquiry or call +386 1 361 90 28.
