is this mattress the same manufacturer as 11" Gel Memory Foam Mattress (5 Sizes)
i bought this one about a year ago and i LOVE it.
This is from the same manufacturer of that mattress. I am glad you are happy with it!
Can you provide the Manufacturer’s name?
It’s available in the linked warranty in the features. 
I have been sleeping on this for two weeks now and I haven’t slept this good in years! My bed requires a box spring and with this on top it is super high (looking for nice steps to make it easier to get into lol) and is magnificent.
So very happy with this!
