The mattress is the most important part of your bed. It is the base from which all other parts depend, including the headboard and the footboard. If one part fails to serve its purpose, all the other parts are bound to fail. Therefore, a gap is inevitable between the mattress and headboard.
If you had a wooden bed, you would need to replace the headboard once a year or so. A metal bed would need replacing after a period of five to six years. However, a bed with no headboard would remain in good condition for much longer.
If there is no gap, dust mites would accumulate at the headboard and cause allergic reactions to the user. Bed bugs are another pest that would breed at the gap. All these things are obviously not possible with a bed without a headboard. You will have to get rid of it.
There are different ways in which you can fill the gap. You can use two plastic or wooden boards that have been cut exactly the right size. These boards should be nailed at the gap. As long as they have been glued well, this will suffice. This way, you can ensure that the gap does not get compromised.
Alternatively, you can actually make your own headboard. There are many plans available over the Internet. Follow the instructions carefully so that you can create something that will be durable and look very good. You could also just use another piece of wood to cover the gap, such as a cabinet board. A bed frame made from two different types of wood is also an option.
When you go to sleep at night, what you see is what you get. So, it makes sense to go for something that looks good and will last for many years. If you are asking “Why is there a gap between a mattress and headboard”, then you should be happy with your choice.
One of the reasons is that headboards tend to get damaged easily. They can be put through rough and tough things and they can even get scratched. This means that the headboard might have to be replaced. Of course, if you are going to replace it, then you need to find a decent bed frame to match your old headboard. You can find great bed frames from second hand shops or from online stores. Just remember that your budget will be a consideration when making your purchase.
Another reason is that your bed frame will give you the space you need to store other important items in your room. Your bed frame will determine the amount of space that you have in your bedroom, including storage. You do not want to fill up this space with items that you will not be using very often. The headboard will give you the right amount of storage room and you can choose what you want on the surface of the bed.
When you have gaps in your bed, you need to determine what you want to do about them. Of course, the obvious thing that you can do is to fill them up. You can buy new headboards and place them in your bed. You can even consider replacing the whole bed frame and installing new headboards. However, if your budget does not allow for this, then you may have to compromise.
