Safety Information

Read all instructions before assembly. Follow safety guidelines to prevent injury or damage.

  1. Lifting: The bed base is heavy. Lift with your legs, not your back. Use two people.
  2. Stability: Assemble on a flat, stable surface. Ensure all screws are tightened securely.
  3. Children: Keep children away from assembly area. Small parts are a choking hazard.
  4. Tool Use: Use the provided tool correctly. Do not overtighten screws.
  5. Weight Limit: Do not exceed the maximum weight limit specified in the manual.

WARNING! An improperly assembled bed base can collapse, causing serious injury. Inspect periodically for loose parts.

Step-by-Step Assembly

Follow these steps in order. Do not skip steps.

  1. Unpack: Lay all parts on a clean, soft surface (e.g., carpet) to prevent scratches.
  2. Attach Support Legs: Screw the adjustable legs into the pre-drilled holes on the underside of the center support beam. Hand-tighten first, then use the Allen key to secure.
  3. Connect Slats: The slats are connected with fabric straps. Unroll the bed base and ensure all slats are evenly spaced and the straps are not twisted.
  4. Install Center Beam: Place the center support beam (with legs attached) under the middle of the slatted base. The beam should run perpendicular to the slats.
  5. Secure Beam to Slats: Using the provided screws and wing nuts, attach the center beam to the designated attachment points on the slatted base. Tighten firmly but do not strip the threads.
  6. Final Check: Ensure all connections are tight. Gently press down on different areas of the base to check for stability and unusual movement.

Tip: Keep packaging until assembly is complete and you are satisfied.

Installation into Bed Frame

The LÖNSET bed base is designed to fit inside IKEA bed frames with side rails (e.g., MALM, HEMNES, Brimnes).

  1. Prepare Frame: Assemble your IKEA bed frame according to its manual, but do not install its mid-beams or slats.
  2. Position Base: With help, lift the assembled LÖNSET base and carefully lower it into the bed frame. The support legs should rest flat on the floor.
  3. Align: Ensure the bed base is centered within the frame. The edges of the slats should sit on or just inside the bed frame's side rails.
  4. Secure (if applicable): Some frames have clips or screws to secure the base. If provided, attach them now to prevent shifting.
  5. Add Mattress: Once the base is stable and level, place your mattress on top.

CAUTION! Do not force the base into the frame. If it does not fit, double-check the frame model and base size compatibility.

Adjusting & Using the Bed Base

The LÖNSET base offers firm support. Some adjustment is possible for comfort and frame compatibility.

Note: For optimal mattress warranty, use with a supportive, non-sagging base like LÖNSET.

Care & Maintenance

Proper care extends the life of your bed base.

  1. Cleaning: Wipe wooden slats with a dry or slightly damp cloth. Do not use harsh chemicals or abrasives.
  2. Inspection: Every 3-6 months, check that all screws and wing nuts are tight. Retighten if necessary.
  3. Moving: To move the bed, always disassemble it. Dragging it assembled can damage the legs and slats.
  4. Storage: If storing, keep in a dry place. Do not place heavy items on top of the disassembled base.

CAUTION! Do not expose the wooden slats to direct moisture or extreme humidity, as this can cause warping.
