Hi turbocats,
I haven’t seen any feedback on the forum about it no but I personally wouldn’t pay too much attention to other people’s experience on a mattress anyway because a mattress that can be perfect for one or even many other people may be completely unsuitable for someone else to sleep on so your own careful and objective testing using the testing guidelines is always much more reliable than anyone elses experience on a mattress (see post #13 here).
Having said that … I would pay significant attention to the specifics of the layers and materials in a mattress (see this article) and compare them to the guidelines in post #4 here (or post them on the forum and I’d be happy to comment on the quality of the materials) so you can identify any weak links in the mattress and make more meaningful comparisons with other mattresses.
