Hi Rob,
Thank you for your question on our website. A pillow-top mattress is a one-sided mattress with a mattress topper stitched on. When the mattress is rotate only your hips are in the same position and the upholstery fibres do not get time to rest. Once the 'topper' has compressed the only thing you can do is replace the mattress.
 


With a two-sided mattress, you can turn the mattress north to south and east to west which means by alternating these over 4 turnings you are using all four sleep positions which helps to even out the natural settlement. When you are sleeping on one side of the mattress you are essentially ironing the underside. If you add a separate mattress topper to replicate the feel of a pillowtop mattress, this will prolong the lifespan of the mattress as well as provide additional comfort as it will be this that is taking the impact of your sleeping and moving around on the mattress instead of the comfort layers. Once this has compressed you can replace the mattress topper.
 
I hope this helps and if you would like any further information or would like to discuss your individual needs, please do not hesitate to give our small friendly team a call on 0161 437 4419.
 
Kind Regards
Michaela
