The bed was not too challenging to assemble compared to other build-at-home competitors. The main reason for the low rating is that you should be aware that the slats are made of metal and have no give. This means you should buy a softer/thicker mattress. A medium firm mattress on wooden slats feels like an extra firm mattress on this frame, so we had to buy an additional mattress topper. Other than that, it has a pleasing design and is delivered in an excellently compact package.
