All of our items are based on standard UK sizing.  If your mattress is also UK sizing, it will be suitable. We recommend comparing the dimensions of your mattress to ours to be sure that it will be suitable.

We have also included the space between slats in the "Details & Dimensions* drop down on our product pages.

Please see below weight limit for our Ottoman Beds:

When lifted in the upright position: Double (45kg), King (50kg), Super King (50kg). When lowered, our beds can take 300kg total weight.
