Took a couple of hours to put together without any power tools. All in all very sold and practical and little one chuffed to bits. I couldn't give it 5 stars because 1. the wood is quite soft as you would expect with pine so does dent/mark easily but a hard wood would probably be more expensive. 2. The Trundle design is good and slots underneath as per the picture, with mattress,  but I don't see anyway this will close with any additional bedding on top, so effectively you would need to remove the bedding after use then close. The mattress we bought isn't particularly deep if that's what your thinking. I suppose you could use the drawers to store the bedding.
