Hi Dolores,

Sadly Vi-spring and John Lewis don't disclose the GSM within this model of mattress, which is essential to make any comparison.

We do compare to a number of Vispring models and you can see the lists here. Maybe have a look at the Artisan Naturals as a starter for ten and then give us a call with your weight and height so we can give you a tailored recommendation.

If you have any further questions please don't hesitate to contact the office on 0161 437 4419
