Hi cmsivley,
“Pillowtop” isn’t a comfort designation, but a method of construction, so I would focus more upon the overall level of plushness that you desire, which of course is quite personal and is most accurately determined through your own personal testing. Additionally, I wouldn’t spend time attempting to exactly replicate a hotel mattress, as those tend to be lower quality items in general and also tend to rely heavily upon various top-of-bed products to achieve their overall comfort.
Whether you choose polyfoam over latex as the upper comfort layer would also be a personal choice, as they have very different characteristics in terms of comfort and durability, with latex tending to offer a bit more of a “buoyant” feel and tending to be more durable.
Regardless of what you choose, always make sure that you find out the information listed here of any item you are considering so you can compare the quality of the materials and components to the durability guidelines here to make sure there are no lower quality materials or weak links in a mattress that would be a cause for concern relative to the durability and useful life of a mattress before making any purchase.
All of the brands that you referenced use good quality materials, and all of them happen to be members here of the site, which means that I think highly of them, their componentry and the advice that they offer. There is also another listing of spring/latex mattress (hybrid) providers in post #2 here.
Overall I can’t tell you “what” to choose, but instead help you with “how” to select a quality product, and to that end I would being your mattress shopping research by reading the mattress shopping tutorial here which includes all the basic information, steps, and guidelines that can help you make the best possible choice … 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”, firmness, and PPP (Posture and alignment, Pressure relief, and your own 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 based on all the parts of your personal value equation that are most important to you (including the price of course and the options you have available after a purchase if your choice doesn’t turn out as well as you hoped for).
In its simplest form … choosing the “best possible” mattress for any particular person really comes down to FIRST finding a few knowledgeable and transparent retailers and/or manufacturers (either locally or online) that sell the types of mattresses that you are most interested in that are in a budget range you are comfortable with and that you have confirmed will provide you with the all the information you need about the materials and components inside the mattresses they sell so you will be able to make informed choices and meaningful comparisons between mattresses and then …
-
Careful testing (hopefully using the testing guidelines in the tutorial) to make sure that a mattress is a good match for you in terms of “comfort”, firmness, and PPP … and/or that you are comfortable with the options you have available to return, exchange, or “fine tune” the mattress and any costs involved if you can’t test a mattress in person or aren’t confident that your mattress is a suitable choice.
-
Checking to make sure that there are no lower quality materials or weak links in a mattress you are considering relative to your weight/BMI range that could compromise the durability and useful life of the mattress.
-
Comparing your finalists for “value” based on #1 and #2 and all the other parts of your personal value equation that are most important to you.
If you have more specific questions after you’ve read through this information I’ll be happy to do my best to be assistive.
