Hi Linda,
 
Thank you for your enquiry.
 
Our Fusion range contains mattresses made from natural latex and for your particular body weight, we would suggest that the Fusion 3 will provide you with an overall medium feel. This mattress comes with a separate 5cm Natural Latex topper providing that extra layer of comfort. If you have any further queries when you have viewed this products, please call our office on 0161 437 4419 and speak with one of our advisors.
 
This mattress can also be used on a slatted base, however, if the slats are more that 3 inches apart, we advocate placing some form of barrier, usually thin (3-5mm) MDF to provide the mattress with a uniform surface upon which to sit and prevent ridging occurring as a result of the mattress dipping into the gaps between the slats.
 
Kind regards.
