Disclosed embodiments relate to apparatuses and methods for wound treatment. In certain embodiments, a negative pressure wound therapy apparatus can include a wound dressing with a spacer layer separated from the absorbent layer by intermediate layers or drapes. The wound dressing can include a first portion comprising a wound contact or tissue contact layer, a first spacer layer, and a first backing layer comprising a first aperture. The spacer layer can be positioned between the contact layer and the first backing layer. The dressing can have a second portion comprising an intermediate drape with a second aperture, an absorbent layer, and a second backing layer. The absorbent layer is positioned between the intermediate drape and the second backing layer. The first aperture and the second aperture are configured to be sealed and allow fluid communication between the first portion and the second portion of the wound dressing.
