Arms Reach Cosleeper

[LG]

Just wondering if anyone has used the arms reach cosleeper and if so some feedback?
I'm wondering - is it possible to put baby in there safely alone? I mean, is there something that can go across the bed side so baby can't get out? does that make any sense?!!
My bub is 9 months old and has always been in bed with me and hubby out BUT Zaccy is starting to take up a lot of room.... and hubby is wanting back in! It's a lot of $$ so i guess i'm just looking for some advice from people who have used one before buying. It just looks like a good option...?
