Hi Veronica,
Thank you for your enquiry. When advising customers in the purchase of fitted sheets to fit either our Artisan or Origins ranges, we always suggest buying extra deep sheets as these usually have enough depth in them to accommodate the mattress and a mattress topper.

I hope this was helpful and please do not hesitate to contact the office on 0161 437 4419 if you require any further information.  Our office hours are 8 am - 8 pm Monday to Friday and 10 am - 4 pm Saturday and Sunday.

Kind Regards

Michaela
