How to assemble a bassinet
A bassinet is a small sleep space for the first months, often on a stand, sometimes rocking or side-sleeper style against the parents' bed. It is built from few parts, but each one, especially the mattress and any side-attach straps, has to be exactly the maker's own.

Parts to check first
Before you start, lay everything out on a soft surface (the flattened box works) and check it against the parts list in your manual.
- Stand or legs
- Basket or frame with fabric sides
- Firm mattress made for this bassinet
- Bed-attach straps, for side-sleeper models
- Wheel or rocker locks
Step by step
Step 1: Check every part against the list and do not use the bassinet if anything is cracked, torn or missing.
Step 2: Build the stand with its bolts and check it stands level with no wobble before the basket goes on.
Step 3: Lower the basket onto the stand and lock it into place; pull up on each side to confirm it will not lift off.
Step 4: Fit the bassinet's own mattress, and check it lies flat and touches the sides all round with no gap.
Step 5: For a rocking model, set the lock so it stays still when unattended; for a side-sleeper, fit the straps to the adult bed exactly as the manual shows.
Step 6: Push the bassinet firmly at the top edge to check it cannot tip, then lock any wheels.
Step 7: Note the maker's age and weight limits, and the milestone, such as rolling or pushing up, when you must move the baby to a crib.
Common mistakes
- Replacing the thin firm mattress with a thicker or softer one.
- Adding bumpers, pillows or positioners.
- Carrying on using it after the baby can roll or has passed the limit.
Safety notes
- Follow your local safe-sleep guidance: baby on their back, on the firm flat mattress supplied, with nothing loose in the bassinet.
- Keep it away from cords, heaters and windows.
This is general guidance for this type of product. Your product's own manual comes first: follow its order, fittings and torque values where they differ from this page.
