How do I keep my 1 year old in bed

Bentley is 14 months old. The otherday he started to climb out of his bed. I can't keep him in it and he's to little to really understand that he has to stay there. This morning I found him in a nest he had made out of blankets in his closet.

    Were gonna change to a toddler bed this evening. Hopefully he does alright. Even if I have to cuddle him to sleep. Believe me I wouldn't complain about that
