Choosing the right opening should be the first decision you make. Side opening frames can be fitted to open on either the left or the right side of the bed, while foot end openings mean that the storage space can be accessed from three sides of the bed.
Whatever opening you decide on, you need to ensure you have unobstructed access to the storage space.
Pay attention to the strength of the built-in hydraulic lift system, which you should consider, depending on your personal mobility needs and the weight of the mattress.
For example, cheaper frames may not be suitable for heavier mattresses. Make sure you have the available floor space for your choice of bed, while checking whether you will be able to easily access the storage area. Meanwhile, if the route from your front door to your bedroom is an issue, consider buying a flat-pack ottoman.
