Hi butch3217,
Welcome to the Mattress Forum!
While 2.5 weeks really isn’t enough time for most individuals to accommodate themselves to a new mattress, it does seem that you’ve settled on a “softer” setting for your personal preference, which is definitely “not the norm” for someone who sleeps upon their stomach, but if that’s what works best for you then that is the most important thing. That’s one of the benefits of the Luxi mattress – being able to switch to different comforts.
If you’re your sleeping well now on the soft setting for the Luxi, I’m curious as to why you’d want to switch to another mattress. It seems as if this setting is working nicely for you, and if the mattress softens up too much for you over time you do have the ability to change over to the Medium setting again.
If you look at the specifications of the Brooklyn Bedding Best Mattress Ever (BME), it uses two different layers of latex foam (2" Talalay and 2" Dunlop) in the upper comfort layers. There is no memory foam in this mattress, and latex has a much different feel from memory foam (more buoyant and not as much “sink in” in general), so this wouldn’t be consistent (at least from a component perspective) with what you’re saying you desire in the feel of a mattress.
Of course, I can’t feel what you feel and the focus of this site isn’t to recommend mattresses or manufacturers for individuals, but instead help people to learn about componentry in order to assist them in making an informed and educated decision (as outlined in the mattress shopping tutorial here). The BME certainly uses good quality materials, but based upon your previous comments I’d be cautious about the componentry being the type that you’re specifying that you desire and prefer.
