Others said that these beds are difficult to assemble. It is not my impression as long as you keep the plant stem up while they made the "clicks". Then we lower the core. It is almost childish. I think this bed is good. Black is a bit harsh, but the overall effect is dynamic and suits us perfectly. We avoided other models with changing platform and other unnecessary items just because you can easily fill it and not bother to make the complicated folding and transport. We took a 7cm thick mattress because what comes with seems pretty symbolic. The bed was purchased to accommodate our grandchildren and our children to avoid transporting a bed of a country to another (they all live in England). We needed something simple, not too bulky, and do not serve much. The delivery was impeccable course.
