Why Does My RV Sleep Number Bed Make Knocking Noise?

I went on a trip with my kids in my RV a while ago, and we had a wonderful day. After all the fun, I went to my RV bed to relax, and guess what. My RV sleep number bed is making a terrible knocking noise that won’t let me sleep. So, I checked the issue thoroughly.

After an extended exploration, I found that the main reason for this particular problem is that the sleep number mattress is loosened from the bed frame, which causes a knocking noise when sitting or lying on the bed.

This is a nightmare for someone trying to go to bed after a long hard day. I found solutions to problems and will discuss them so you don’t have to face them.

1. Air Leak

RV Sleep Number bed mattresses are inflated with air. So, sustainable air is necessary for the mattress to maintain a balanced level and shape. But there is always a possibility that the mattress can get punctured.

A punctured mattress will leak air from its inner segments, resulting in a smaller or not-perfect mattress for the bed frame. So, when you try to rest, a slight movement on the bed will create a knocking noise with the bed frame.

2. Loose Bed Frame

It is not always necessary that the mattress is the reason for the knocking sound of an RV Sleep Number bed. The bed Frame can also be the reason for that.

Sometimes after usage, when your mattress moves frequently, it detaches from the frame and creates a knocking noise unless you adjust the bed frame.

3. Faulty Air Pump/ Uneven Air Level

This is very common and happens to many. The air pump for the RV Sleep number mattress does not last very long and becomes faulty after a few months or a year.

A defective air pump fails to inflate the bed mattress properly and always leaves a gap between the mattress and the bed. Because of this, you keep hearing the irritating knocking noise when you get on your bed.
