Hi Roy,

Thank you for your enquiry. Our zip and link mattresses are only supplied with zips on the top and bottom of the inside edge, we do not put zips on the outside edges. This means that if you opt for a split tension, you will only be able to flip top to toe unless you are prepared to change sides in which case you can flip over as well.

I trust that this clarifies the position for you. If you would like any further information please do not hesitate to contact the office on 0161 437 4419.

Kind Regards
