Almost didn’t order this item due to the low rating. However, I read the instructions and followed them. Turns out these wooden bed slats are sturdy and good quality. The description for the queen size says 80 x 60“. I measured the inner part of my bed. The measurements matched. The slats fit my bed perfectly, no problems with it dropping down to the floor or collapsing. So I guess the low rating is due to people misunderstanding, not following directions, and not measuring their beds properly. What people need to understand is that just because it’s a queen size doesn’t mean it fits all queen sizes. That’s why it’s important that you measure the inner part of your bed frame where your slats will be sitting. For example, I assumed that I could use the bed slats from my previous bed for my new bed since they’re both queen beds. However, the slats from my previous queen bed didn’t fit my new bed. So it’s important to read directions and take measurements.
