Hi testerman,
I would certainly avoid buying another hotel mattress. They are made by Simmons and I would also avoid any of the major brands (such as Simmons) as well even if they have a similar design or “feel” similar to the W Hotel mattress … see this article) because they tend to be overpriced compared to other similar mattresses and they also tend to use lower quality materials that can soften and break down prematurely. There is more about hotel mattresses in post #3 here and there is more about trying to “match” the the W Hotel mattress in post #4 here.
The first place I would start your research is the mattress shopping tutorial here which includes all the basic information, steps, and guidelines that can help you make the best possible choice inside your budget range … and perhaps more importantly know how and why to avoid the worst ones.
Two of the most important links in the tutorial that I would especially make sure you’ve read are post #2 here which has more about the different ways to choose a suitable mattress (either locally or online) that is the best “match” for you in terms of “comfort” and PPP (Posture and alignment, Pressure relief, and Personal preferences) that can help you assess and minimize the risks of making a choice that doesn’t turn out as well as you hoped for and post #13 here which has more about the most important parts of the “value” of a mattress purchase which can help you make more meaningful quality/value comparisons between mattresses in terms of suitability (how well you will sleep), durability (how long you will sleep well), and the overall value of a mattress compared to your other finalists.
The tutorial also includes several links to lists of the better online options I’m aware of and they include many good quality/value mattresses that would be well inside your budget range.
If you let me know your city or zip code I’d also be happy to let you know about any of the better options or possibilities I’m aware of in your area.
