Hi carolyna,
While other people’s comments about the knowledge and service of a particular business can certainly be very helpful, I would always keep in mind that you are the only one that can feel what you feel on a mattress and I would be cautious about about using anyone else’s suggestions, experiences or reviews on a specific mattress (either positive or negative) or review sites in general 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 and in many if not most cases they 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 may be completely unsuitable for someone else to sleep on (even if they are in a similar weight range). In other words … reviews 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).
I would be especially cautious about reading reviews on any manufacturer’s or retailer’s website because to different degrees almost all of them will be moderated and/or filter out any overly negative reviews. Just ask yourself if you were a manufacturer or retailer that was focused on selling mattresses would you post every single negative review whether you believed the comments were justified or not?
These are very different mattresses that use different materials and components so they would be somewhat of an apples to oranges comparison.
Assuming that the materials in a mattress you are considering are durable enough for your body type and meet the quality/durability guidelines here relative to your weight range … the choice between different types and combinations of materials and components or different types of mattresses are more of a preference and a budget choice than a “better/worse” choice (see this article).
Buying a mattress based on other people’s needs and/or preferences would be something like buying shoes or clothing based on other people’s sizes and preferences.
There are some comments about Luxisleep in post #10 here and there are some comments about Novosbed and some of the other simplified choice mattresses in post #2 here in the simplified choice mattress topic.
While you are the only one that can feel what you feel on a mattress so nobody can speak to how any mattress will feel for someone else or whether it will be a suitable “match” for you in terms of comfort, firmness, and PPP (Posture and alignment, Pressure relief, and your own Personal preferences) when you sleep on it … neither one of them have any lower quality materials or weak links that would be a cause for concern in terms of the durability and useful life of the mattress for anyone that is in a more average weight range (the lower 200’s or so or less).
