How does a king’ or larger mattress ridge develop?

If you've had a king-sized or larger mattress for a while, you might have noticed a ridge forming in the middle, running from head to toe. You might be wondering if it's normal wear and tear, a flaw from the manufacturer, or a sign of a low-quality mattress.

Actually, this occurrence is quite common in larger mattresses, often dubbed the "king's ridge." It's not indicative of mattress quality but rather a consequence of the mattress size and how you use it.

The primary cause behind the formation of a ridge in a mattress is the uneven distribution of weight across its surface.

"People naturally gravitate towards their preferred sleeping spot, leading to repetitive pressure on specific areas of the mattress.

Is it possible to eliminate a king's ridge once it forms? It's challenging to completely erase a king's ridge, but there are steps you can take to minimize its impact. Here are some options:

  1. Add a mattress topper or a thick quilted pad. A latex topper is less prone to developing impressions due to latex's natural resilience.
  2. If your mattress is flippable, consider flipping it. However, always consult the manufacturer first, as many modern mattresses with separate support and comfort layers are not designed to be flipped.
  3. Spend time lying in the middle of the mattress when you're awake, such as during leisurely activities like reading on a Sunday afternoon. Regularly using this less-used area can help redistribute the weight and even out the surface over time.
