Hi Andrea,

 

Thanks for your question.

 

The simple answer to your question is no, a mattress shouldn't sink noticably that quickly unless its not being maintained or the sleepers are over the weight tolerance for that particular mattress. I'm assuming neither apply to you in this case! Unnatural settlement is a noticeable dip of more than 1.5 inches.

 

What is more than likely is that the memory foam layer is a thin low quality foam. I.e, 2cm. This means that once it settles and compresses slightly your left with very little in terms of comfort. The cheaper memory foam degrades very quickly so can be a false economy. The body impression on both sides suggests this.

 

With no turn mattresses you can only ever use one side meaning the life of the bed is reduced, for that reason at John Ryan the majority of our mattresses are fully turnable allowing even distribution of all wear and tear and settlement of all fillings across both sides.

 

Our own Hybrid range gives a very similar sink in sensation to Memory Foam but without the heat issues associated. Both come with completely detachable toppers that can be flipped and turned to increase the lifespan.

 

 

We would need to know body weights to discuss spring tension and suitability but below are our own guidelines;

 

Bodyweight	Spring tension
Upto 16 Stone / 50-101kg	Medium (1.4mm)
16 Stone / 101kg Upwards	Firm (1.6mm)
Available in Bespoke Products (Please Call)	Soft (1.2mm)

 

I hope this has answered your questions fully but if you do have any further queries please don't hesitate to contact our office on 0161 437 4419. Our office is open Monday to Friday 8am to 8pm and Saturday and Sunday 10am to 4pm.

 

Kind Regards, Lee.
