Mattress comfort layers - microcoils
Most innersprings are not suitable as a comfort layer since they are not so comfortable to sleep on directly although some can provide the "conforming ability" to help a comfort layer do its job. There is however a type of innerspring called a "microcoil" which is made by several manufacturers and which is designed specifically for use as part of a comfort layer. They are made from thinner more flexible wire, have more coils (usually over 800) and have less thickness so they can fit in a “eurotop" or "boxtop" mattress since they can not be made as thin as foam or fibers. They are typically used with a thin foam layer or quilting layer over them so you won’t feel the individual coils. As a comfort layer, they are much more pressure relieving and comfortable than sleeping directly on their more supportive innerspring cousins.
While they are more expensive than the low grade polyfoam that is typically used in the upper layers of a mattress, they are less expensive than a good quality foam like HR polyfoam, latex, or high quality memory foam. They also have a high level of resilience and point elasticity and so like latex or HR polyfoam can provide support to the recessed areas of the body that are not in direct contact with the support layers of the mattress. They are also more durable and less prone to body impressions than the lower quality foams that are so often used in mattresses.
They are typically used over innerspring support cores (probably because the same manufacturer or supplier would likely make both), and are often called “coil on coil” mattresses. The same or similar terms are also used for other types of innerspring combinations so be a little careful when you hear this term that it is actually referring to microcoils being used in the comfort layers. There is also no real reason that these couldn't be added over a polyfoam or latex core except that it may need a cushioning layer to protect the foam below it. It is rarely found with this combination however. Overall, they represent a good value option in a mid range mattress that is well worth testing as an option if they are available in your area.
The good thing about Naturepedic, however, is that they do accept returns on their beds. The return shipping can be costly, so confirm with them ahead of time what this will cost you. I've also seen their microcoil topper on BedBathandBeyond as well as Amazon. The return process for just the topper may be easier through those retail points.
I saw another person posting about the Naturepedic microcoils here; this member seemed to like them (and perhaps is a better judge, since I spent so little time on this layer):
Naturepedic does have excellent trial periods and return policies, but do note that they apply only when purchasing directly from Naturepedic and not from retailers that also sell their mattresses.
With your MCS condition, you likely have few options other than Naturepedic
Hope this helps!
Welcome to The Mattress Underground! We viewed the YouTube video link you provided of The Wool Room. Thank you for this info. Naturepedic will be somewhat similar. Another US based company you may want to consider is White Lotus Home. www.whitelotushome.com/mattresses/
As far as microcoil systems and pressure relief, there a several factors in the design of the coils and their location in the mattress comfort system that will directly influence the pressure relieving capabilities. The material technology is still developing but has not achieved the support/pressure-relief capabilities of latex.

I spent the day at naturepedic trying the plush coil bed with one side soft microcoils and the other side medium microcoils.
I loved the feeling of the medium around my hips and lower back. They seemed to support my lower back even when I was on my side. However they made my shoulder hurt.
The soft microcoils were best for my shoulder but when sitting on the bed I found I bottomed out into the main coils and made it feel like a cheap bed. Was comfortable lying down but sort of liked the more active feel of the medium better.
Just wondered how your shoulder was with the medium micro coils? It sounds like you didn't try the soft or did you? If you did what did you see the pros and cons of each?
I also thought maybe the medium microcoils would hold up better over time. How are yours doing?
i don’t have any muscular skeletal problems i struggle with so shoulders feel fine. i only sleep on my side for a short bit then always end on my back. the time i’m on my side i think i’m usually in an unusual twisted and stretched out pose which changes the pressure distribution. what i’m saying is i don’t think my shoulders aren’t perpendicular with the bed.
i’m 6’0” 175# if that gives you any useful data.
my eos is just over 3 years now and has shown zero signs of sagging or stretching out. once a year i flip stuff around for even usage (be careful with the support coils tho... they have a specific direction they’re supposed to go)
zero regrets with my purchase. good luck.
