Hi mrstree,
Outside of dn’s general comments and link to the mattress shopping tutorial and about bamboo fabrics … there are also some memory foams that use bamboo charcoal as a filler in the memory foam. There are a few comments about them in post #6 here and in post #4 here (coincidentally in response to someone else from Katy, TX).
The mattress you are mentioning sounds very similar to the BedBoss or mLily mattresses (under a different name) which both use bamboo memory foam in the quilting layer and are made in China. They are both CertiPur certified and would be reasonable choices in terms of quality/value for someone who is comfortable with Chinese memory foam. Katy Wholesale isn’t listed on the CertiPur site however so I would want to know who makes their mattresses or find out which of the Chinese foam manufacturers pours their foam to make sure that it really is CertiPur certified. I would also be cautious with memory foam mattresses that have been compressed for long periods of time with shipping overseas or storage in a warehouse because this may affect the durability of the foam. You can see the basic criteria I use for memory foam mattresses in post #10 here.
I would also be a little bit cautious because of their comments here about cheaply made imports from China when it appears that they also are a cheap mattress imported from China Although “on the face of it” they appear to use good quality materials, I would also read post #6 here about cheap Asian imports.
More than this though, a mattress is one of the most important purchases you can make in terms of your overall wellbeing especially when you have difficult health challenges where the suitability of a mattress is particularly important. In this case the knowledge and experience of the person you are buying from and their ability to help you make a choice that is suitable for your specific needs and preferences and the costs involved in a return (and how long you have to wait to be able to return it) and what you would be sleeping on in the meantime can play a significant role in the value of a mattress purchase and your personal value equation.
Comfort and softness are subjective and relative to each person and their body type, sleeping positions, and individual preferences and sensitivities so only your own personal testing or experience in terms of PPP (Posture and alignment pressure relief, and Personal preferences) can really answer this. Thicker memory foam layers generally provide more softness and ability to conform to your body shape more than thinner memory foam layers but it also depends on the specific properties of the memory foam. Thicker memory foam layers are also more risky in terms of alignment because they can allow the heavier parts of your body to sink in further than the lighter parts of your body before they are “stopped” by the support layers. A mattress is always a balance between the softness and thickness of the comfort layers that provide the primary pressure relief and the firmness of the support layers that provide the primary support of the mattress. Too much or too little of one or the other would mean that mattress may not be suitable for you but there is no “formula” to predict this so if you can’t test a mattress in person you are completely dependent on the knowledge and experience of the company you are buying from and their ability to help you make the most suitable choice.
The first step I would suggest though is to read the tutorial post and the links inside it that dn linked in his reply.
