Here lies the possibility for conflicting information.
I am 185cm and 63.5Kg and my wife is 161cm and 44Kg, according to your spring tension chart i would be suitable for a soft tension but according to your other two references i would be a medium.
Could you please clarify which would be the better option for me?
I think a detailed post on height, weight and tension would be a great addition to the understanding beds section, or even better a calculator! I understand that there are many factors involved but you could provide a calculator on a few inputs like
side (maybe curled or straight), back or front sleeper
I essentially want to be told what mattress is right for me. Whatever it takes to get my spine is as straight a position as possible.
I am going to do some calculations using a profile picture of myself which i will be able to roughly calculate the weight per area i exert on the mattress and do the same for my wife. Could you provide a correlation between weight per area and spring tension? The chart you provide must use a similar method.
It would be very difficult for us to make a chart based on height weight and tension purely because it really is just a guide. The overall choice is personal preference. One persons medium is another persons soft.
At your body weight we would generally advise a medium spring tension in order to give you the correct support. It would be a good idea for you to go and try the relevant Vi Spring mattresses that our Artisan range have a similar feel to in order to see which you do prefer. The springs are only one part of a mattress and are there to give you the correct support, whereas, the upholstery layers are there to give you the comfort.
I hope this assists but if you do require any further information, it may be better to have a chat over the telephone – 0161 437 4419.
