Hi there ZachBasa,
Welcome to the Mattress UnderGround,
Happy to have you here.
Well first, wow. Your Ghost Bed gave you 10 years of service, I would say that is a pretty good run. Have you tried rotating the mattress to determine if the mattress is the issue or your preferences have simply shifted.
Most hotel mattresses are designed to hit that medium firm sweet spot (for as long as they hold up) and by happenstance many hotel guests will feel rejuvenated on the mattress because the one at home is typically on the way out. This a common theme that happens, and usually folks run to the hotel bedding website for a costly, non returnable mistake.
Latex mattresses can be very resilient, made to accommodate dissimilar sized sleepers preferences and be made in a hybrid or full on latex combination.
If it is latex you seek, most of the TMs here at TMU are the best in the industry when it comes to latex mattresses. You need only to go as far as picking one and collaborating with them to find you a perfect fit when it comes to latex and latex hybrids.
The nolah natural is nice offering and reasonably priced. It is a tri-zoned mattress, which will boost support in the lumbar and typical problem areas. Given both your lighter weights, and the fact you sleep on your back, you may not feel the effects of the zoning as much as sleepers who carry more weight in the middle.
Zoning has its pros and cons.
If the zoning is too pronounced or not well matched to your body type and sleeping position, it could lead to discomfort. For instance, if the lumbar zone is too firm or too soft, it could exacerbate rather than alleviate back pain.
For combination sleepers, zoning can sometimes cause issues as the support might not adjust well to different sleeping positions. However, since you primarily sleep on your back, this is less of a concern for you compared to a combination sleeper.
Shorter sleepers (under 5’5 ) might find that the zoning in a mattress doesn’t align well with their body, especially if the zones are designed with averages in mind. For example, if the lumbar support zone is placed too high or too low, it could lead to discomfort or improper spinal alignment.
Zoning that is not well-adjusted for shorter bodies might not effectively alleviate pressure points, which can affect comfort and support. For instance, if the mattress has firm zones where a shorter sleeper’s body needs softer support, it could lead to discomfort.
Some mattresses offer adjustable or customizable zoning options, which can be beneficial for shorter sleepers. These options allow for better alignment and support adjustments based on individual needs.
Before diving into a zoned mattress, you need to speak with the mattress expert wherever you are looking at their mattress to ensure it is a good fit for your height and weight.
On the positive side, the TMs here ship nationwide and have experts on staff to tackle these issues.
Staying under the $1600 price point should not be much of an issue for a latex hybrid. @Arizona_Premium ultimate hybrid, this is a combi zone spring layer, but arranged slightly different, as it offers nice edge support, @Sleep_EZ hybrid offers an enhanced edge support zone, and is flippable with a firmer side and a softer side based on how you flip it. There are just a couple of examples of latex hybrids within your stated budget and preferences.
If you feel ambitious enough, these folks can help you design a latex hybrid to to meet exacting specifications.
In the online genre, you may find the Ecosleep or Ecosleep Luxe, or birch natural more suitable from 3z brands over the nolah, made by the same company. Naturally, all of these are not customizable, but hit your checkboxes, made in the USA, offer nice support systems, and latex combined with other natural fibers to make nice quality offerings.
Hope this helps get you jump started.
