Hi Anne.

Thank you for your question. Do you mean supports going side to side as well as the head to foot support? Usually, double ottomans have a single support from top to bottom and the two slat units clip into this to enable the whole unit to lift. Not really too sure what you mean.

As for mattress type, I would hope that you are not going down the open/continuous coil route. Even though pocket springs like a flat sprung edged support, I would have no qualms about using them on an ottoman base.

However, you will need to add some sort of cushioning on top of the slats to prevent the slats digging into the underlying upholstery - assuming that your mattress is two-sided of course.

If you would like any further information please do not hesitate to contact the office on 0161 437 4419.  Our office hours are 8 am - 8 pm and 10 am - 4 pm Saturday and Sunday.

Kind Regards

Michaela
