I needed a bed guard to ease the transition from cot to bed for my 2 1/2 year old. I looked at several, and chose this one as it said suitable for all bed types (I have a slatted wooden bed and many were unsuitable).
The bed guard was easy to assemble and fit on the bed base - I did it on my own but an extra pair of hands would be useful for lifting the mattress. It looks great and matches the wooden bed perfectly. It looks similar to the wooden cot bars so my son feels more secure. The guard rail clicks in and out of the base, making it easy to remove for bedtime stories and click back on again at lights out time. It feels very secure when fitted, and so far my little boy has settled straight into his big bed with no falling out incidents to put him off!
It is slightly more expensive then the fabric type bed guards, but I think well worth it.
