Bought this cot for when my grandson stays..it was easily put together and very stable..the plastic guard covering the top is great for when little mouths are inclined to bite whatever they can...the mattress is good fit also.the base has 3 settings so I raised to the centre one for now but will lower as he gets bigger ...no doubt he will try to climb out .The cot is safe and stable with one side off, and as it's a good size will be used as a "day bed " as he gets older.Really happy with this cot..Great price..fast delivery and good quality.Thankyou
