HI kc12,
Luma Sleep is a “newer” member here to the site, and the brand itself isn’t as old as some of the others in the “simplified choice” category, so there isn’t as much feedback here on the forum so far. A search on Luma (closed business as of 2023) will bring up where they have been mentioned here on the site. Their products do use good quality and durable materials, and I do think highly of them and the advice they provide.
While I know that you’ve been a member here of the site for a while, but it bears repeating for those who may be browsing through this thread for the first time…I always advise to be cautious about putting too much stock into other people’s comments about how a mattress is working for them and then applying that to you, as you are the only one that can feel what you feel on a mattress and I would be careful about using anyone else’s suggestions, experiences or reviews on a specific mattress (either positive or negative) as a reliable source of information or guidance about how you will feel on the same mattress or how suitable or how durable a mattress may be for you. In many if not most cases these comments, no matter how well meant, can be more misleading than helpful because a mattress that would be a perfect choice for one person or even a larger group of people in terms of comfort, firmness, and PPP may be completely unsuitable for someone else to sleep on (even if they are in a similar weight range). In other words … reviews or other people’s experiences in general won’t tell you much if anything about the suitability, quality, durability, or “value” of a mattress for any particular person (see post #13 here). Just something to keep in mind.
