Check before you buy

Age and bed type. Use only for toddlers who have moved to a toddler, twin or full bed, never in a crib, bassinet or with infants. Soft items in an infant's sleep space are a suffocation risk, and padded crib bumpers are banned in the US.
Firmness. Choose high-density foam that holds its shape when a child leans on it rather than collapsing flat. A soft bumper compresses under a rolling child and stops nothing.
Under-sheet fit. The bumper should sit under the fitted sheet and have a grippy or flat underside so it does not shift on the mattress. A bumper that slides or rides up can be pushed off the bed, or create a gap a child can slip into.
No gaps. The mattress must sit tight against the frame and any wall, with no gap between bumper, mattress and headboard. Gaps at the mattress edge are an entrapment hazard.
Length vs bed side. Match the bumper length to the open side of the bed, and use a pair or a hard rail if both sides are open. A bumper that is too short leaves an easy roll-out zone at the end.
Washable cover. Prefer a removable cover that is machine washable, ideally with a waterproof layer. Potty-training accidents are common at this age.

Questions

Bumper or bed rail?

A foam bumper is a low edge that discourages rolling out on a low bed, while a hard rail is taller and better for higher beds or very active sleepers.
