This item is well-made, easy to transport, and definitely holds a mattress firmly. If you are buying a mattress that needs slats that are close together, this will accommodate. I got the version with the vertical slats to put on top of some horizontal wooden slats. I did pay extra for the heavier slats that are covered in fabric, and I’m glad I did. It works wonderfully. Now I am thinking of getting the same product in horizontal slats. For another bed.
