Hi Sweet Dreams,
Thanks for taking the time to share your comments and feedback … I appreciate it!
As you know … Somnigel is a type of buckling column gel similar to nexgel or intelligel. Post #2 here and post #2 here and some of the posts they link to have more information about buckling column gel as well.
It’s certainly a high quality and durable material with a unique feel and performance but I also hope you also had the chance to find out all the type and quality of all the other layers and materials in your mattress as well (besides the latex) to make sure there are no weak links in the design (see this article).
Congratulations on your new mattress … and thanks again for the feedback 
Phoenix
