Learn how to replace the support beam and base plate B on your Sebra Sengen crib, with a step-by-step process and label check before you order.

Quick answer

Before you order a Sebra Sengen support beam or base plate B, confirm your crib carries both the EU Ecolabel and FSC labels—these spare parts are only guaranteed to fit labeled products. Then follow the assembly guide for your specific part and model.

Why the label check comes before the part number

Sebra spare parts for the Sengen Baby & Jr. crib are tied to labeled production. If your crib lacks the EU Ecolabel and FSC labels, Sebra cannot guarantee that a support beam or base plate B will fit, and they cannot help you source other spare parts. Checking the label first saves you a return and a delay.

The support beam is marked as part C and the base plate as part B in the assembly guide. These letters refer to positions in the crib's construction, not to a universal fit across all Sebra cribs. Use the guide that came with your crib or the current assembly instructions to confirm which letter applies to the part you need.

What each part does—and when replacement makes sense

The support beam (part C) is a structural component that helps hold the crib's base in position. The base plate B is the platform that supports the mattress. If either is cracked, warped, or missing, replacing it restores the crib's intended setup rather than improvising with another material.

Replacement is not a repair for every squeak or wobble. Loose fittings often come from assembly bolts that need tightening, not from a failed part. Inspect the part itself for visible damage before you order a replacement.

Tools and preparation you will actually need

You will need the assembly guide for your Sebra Sengen model, the correct replacement part, and the tools specified in that guide. Clear the crib of bedding and the mattress before you start. Work in the room where the crib stands, since moving a partially disassembled crib through doorways adds risk.

Step-by-step: replacing the support beam or base plate B

Check the labels on your crib: Look for both the EU Ecolabel and FSC labels on your Sebra Sengen. If either is missing, stop and contact Sebra before ordering, because fit is not guaranteed. No labels means no guaranteed fit—do not order yet.
Identify the part letter in your assembly guide: Open the assembly guide and confirm whether the damaged component is labeled C (support beam) or B (base plate). Match the letter, not just the visual shape. Ordering by shape alone is the most common mistake.
Clear the crib and remove the mattress: Take out bedding and the mattress so you can access the base area. Work with the crib on a stable floor, not on a slope. A clear, level workspace prevents fasteners from rolling away.
Disassemble only what the guide specifies: Follow the guide's sequence for removing the old part. Keep screws and fittings in a container labeled by step so you do not mix lengths. Removing extra parts creates unnecessary reassembly risk.
Fit the new support beam or base plate B: Position the replacement part exactly as shown in the guide, then tighten fittings in the order given. Do not overtighten—stop when the part sits flush. Check that the part sits flush before final tightening.
Reinstall the mattress and test stability: Put the mattress back, press gently on the base, and check for movement or gaps. If anything feels loose, revisit the fitting steps before use. Any wobble means recheck the fittings, not the part.
