Sebra Sengen Baby & Jr.: How to Raise the Bed Base Safely

Quick answer

To raise the Sebra Sengen Baby & Jr. base to the top position, fit the dedicated hævesæt (two support rails and four screws) and follow the crib's assembly guide for the exact placement. Never improvise with loose hardware or force the base into a position the frame was not designed for.

Step-by-step: raising the Sebra Sengen base

1. Confirm your crib model and position: Check that your Sebra Sengen Baby & Jr. is a model with an adjustable base and that you intend to use the top position. The hævesæt is only for cribs where the base can be raised. If your crib does not have an adjustable base, stop here — the hævesæt will not fit.
2. Unpack and count the hævesæt parts: Lay out the two del I support rails and four del P screws. Match them against the parts list in the assembly guide before touching the crib. Missing or extra hardware is a sign to contact the shop before assembly, not to substitute screws from a drawer.
3. Empty the crib and remove the mattress: Take out bedding, the mattress, and anything stored under the base so you can reach the base frame and see the mounting points clearly. Working with an empty crib prevents the base from shifting while you loosen or tighten fittings.
4. Identify the correct mounting points in the guide: Open the assembly guide and locate the section for the top base position. The guide shows which parts go where; follow it rather than guessing from the hardware alone. Photograph the current base fittings before you loosen anything, so you can reverse the change later.
5. Fit the support rails and secure with the screws: Position the two support rails as shown in the guide, then insert and tighten the four screws. Tighten gradually and evenly rather than driving one screw fully home first. A base that rocks or creaks after tightening usually has one screw not fully seated — recheck all four.
6. Check stability before adding the mattress: Press down on the base at each corner and along the middle. It should feel firm with no movement between the rails and the frame. Any wobble means the rails are not correctly seated; do not put the mattress back until it is resolved.
7. Reinstall the mattress and confirm the rail height: Put the mattress back and check that the distance from the mattress surface to the top rail still suits your child's stage. If your child can sit up or stand, the raised position is no longer appropriate. Recheck the base height whenever your child reaches a new mobility milestone.
