Thanks for your question.
At your body weight we would match you with a Medium spring tension to get the correct level of support;
|Upto 8 Stone / 50kg||Soft
|8-16 Stone / 50-101kg||Medium
|16 Stone / 101kg Upwards||Firm
Side sleepers need to avoid anything too firm in the top layers whereas front sleepers need to avoid anything too soft in the top layers. As such, you should be looking at more of a medium feeling model in it’s upholstery.
Have a look at our Origins Pocket 1500
or Artisan Naturals
. Both have that medium upholstery providing a slight sink but not too much with the main difference being that the Artisan range tend to last longer as standard due to the construction with natural fillings but also provides a cool sleep surface.
Please note that with either of those mattresses you would need to buy a Mattress Encasement from somewhere like Allersafe online. This will help with your allergies.
From there you would be better looking at a bedstead as you really want to avoid a base with any sort of fabric on it.
I hope this helps but if you have any further queries please don’t hesitate to contact our office on 0161 437 4419.
Kind Regards, Lee.
