We spent a really long time trying to find the right bed for our son after he out grew his cotbed and this one is perfect. He's a complete fidget so could never have been in a bed without sides. The fact that the side barrier on this is removable is perfect because it stops him falling out of bed now but when he gets older and might be embarrassed by it and want a big boy bed, we can simply lift it off. The bed feels really well made and sturdy. There have even been a couple of nights when I've slept on it with my son when he's poorly and it didnt even so much as creak. The storage drawer underneath is a total bonus and slides in and out really easily without sticking. 
Totally recommend. A fantastic bed for children transitioning from small   to big.
