Worked awesome for our 7 day holiday trip with our 2 year, 4 month old ACTIVE toddler. Was sized for a full size mattress, with some room to spare. Since we were in one room together, having a sheet cover the tent made it so we didn’t have to worry about light waking her up during noontime naps and 7pm bedtime. We kept one side “open”, though, so we could still watch her from the other room via our portable baby monitor. Great value!
