I (30 something stay at home mom) was able to assemble this by myself without any additional tools. The directions were only pictures so it took me a while to figure them out. But overall, I’d say it went quite smoothly. The bed feels sturdy, but it’s much closer to the ground than I expected. It’s the perfect height for my young child, but might feel uncomfortably short for a teen or adult. It would not work for someone who has any difficulty getting up and down. The peel and stick bars were an unexpected bonus for keeping the mattress in place. Not sure how long they will stay sticky, but it’s nice for the time being. Overall, I’d recommend this listing. Hugh quality for low cost.
