It’s common to need storage for a bed, usually because it’s a spare that’s only used during the holidays or for visitors.

What factors affect the required storage space?

Apart from the size of your mattress, the following factors will affect the size and type of storage unit you should be looking for.


What you are storing

Are you storing a mattress or a base as well? Is there a headboard? These questions will help determine what size unit you need. Also, consider the height of the bed. This can vary depending on the type and manufacturer.


The storage length

Short-term versus long-term storage will play a role in the size you need. A mattress can stand on its side for a short time. If you’re storing a mattress for more than a couple of months, you’ll need to have the space to lay it flat. 


Storing conditions

Squeezing a mattress into a space that it just fits is not a good idea. Apart from potentially damaging the mattresses, you’ll need space to manoeuvre around the bed in the unit. You need to ensure good air circulation around the fabric to prevent mould.



It’s no good finding the right size storage unit if you can’t access it or the door is too small to fit the mattress through. Find a storage unit with a large garage-style door and one that has relatively easy access. If you can drive your car up to it, even better.


What size storage unit fits a double or queen bed?

If you’re storing a double or queen bed for a long time (meaning it has to be flat), find a storage unit that is roughly 8 to 9 m2 with the right dimensions to fit the bed with some space left over. For example, a 3 m x 3 m space or a 2.5 m x 3 m space would work well.


What size storage unit fits a king bed?

To store a king-size bed long-term, it’s safest to get something 9 m2 and up. This will allow ample room to manoeuvre the bed in and leave enough space around it for ventilation and access. Extra storage space will come in handy for storing bedding and other items.


Tips for storing a bed

Before storing, you must prepare the bed. Start with a thorough clean to remove dust or marks. Once the mattress is completely dry, wrap it in a mattress bag for short-term storage. Alternatively, use furniture blankets for long-term storage to avoid condensation.


If the bed has removable feet, take them off to prevent damage and store them in a box or bag with the bed. Try not to store the mattress on its side for long periods. If this is unavoidable, rotate the mattress frequently.
