Hi Caeser,
Thanks for the question and the information. All toppers will soften up in time regardless of construction, but it will be difficult to tell on a day to day basis, as it happens gradually. Also FYI, we will probably move this post to a more appropriate topic once you reply.
Here is a link regarding the durability / BMI / support for 12" hybrid Silk and Snow… right here. This article discusses your concerns about the quality of
Regarding the question about support of coils:
In general the properties and support of a spring unit are given by many interrelated factors such as wire gauge - typically between 12 and 19 (the lower the gauge number the thicker the wire and the more firmer coil), the number of turns /wraps of coils (the more turns the softer the coil), the diameter and the number of coils (the higher the diameter the softer the spring), You do not list the gauge /diameter for a the S&S While none of the spring units would be the week link within a mattress in terms of durability all the layers work together and the pocket coil is part of the general design of the mattress and in this case I’d tend to focus on how well the mattress “as a whole” matches your specific needs and preferences in terms of comfort, firmness, and PPP (Posture and alignment, Pressure relief, and your own Personal preferences)
Concern with a silk blend fill pillow top:
Yes, quilted pillow tops generally will sag less, but any pillow top made of fibers used in a quilting machine will compress over time. Whether it is silk, polyester, wool, cotton, etc, etc. They are comfortable when you lie on the mattress but will break down quickly…these fibers are not of the quality of high-end foam or latex to be so close to your body. Not saying they don’t feel wonderful to many people, I am sure they do.
Thanks again
