Hi Mr Banks, 
 
 
Thanks for the question, 
 
 
With our Ottoman, there is no need for a support to be used. With a front lift construction method, supported by high-quality gas struts, it enables you to lift the entire mattress up and utilise the significant storage space beneath it.
 
 
The depth of the ottoman storage is 25cm or 10″. The height if the base is 40cm including castors.
 
 
I hope this helps. 
 
 
Kindest Regards
