Hi Andrew,
 
Thank you for your enquiry.
 
Having viewed the link you have provided, we note that aside from showing the product as a pillow top, there is no other information available in respect of the construction or the upholstery in terms of GSM (grams per square metre), which make providing any form of opinion as to quality and performance impossible. For the same reason it is impossible to provide a comparison.
 
We do not make pillow top mattresses for the reasons detailed in the link. If you are able to obtain any details in respect of the Simmons product, please call our office on 0161 437 4419, when we will then be able to advise further.
 
Kind regards.
