Buy a good box spring at Auping. The luxurious Auping box springs consist of two or three layers:
An upholstered box: the base, containing pocket springs for good support and a mesh base for good ventilation.
A box spring mattress with pocket springs: this is an upholstered mattress, for optimal support while you sleep. You can also put a white mattress on top of the box.
A topper: a thin top mattress that determines comfort. If you choose a box spring mattress, you put a topper on top of the mattress. This determines the comfort feeling. For example, do you like to sink in a little deeper or do you prefer to lie a little firmer?
The upholstered layers make a box spring bed look nice and soft and comfortable. Because of the double layer of pocket springs (in both the box spring mattress and the box), a box spring often feels a little softer than a normal bed.
