Hi mbuyer,
Welcome to the Mattress UnderGround Community. Thanks so much for your question.
The MLILY ChiroPro Firm mattress could be a great choice based on your preferences as a side sleeper, especially since you found it comfortable in-store. The combination of memory foam and high-density support layers typically offers a good balance of comfort and support for side sleepers. The usual recommendation for HD foam is at least 1.8lb in the comfort layer (1.5lb as a base layer between the mattress and foundation is acceptable. Viscoelastic memory foam is recommended at 4lb density or above, although, there are constructions that can work with 3lb and above.
Since you’re under 100 lbs, you should avoid sinking too deeply into the mattress, which aligns with your preference for a medium-firm feel and a quicker bounce-back. The firmer nature of this mattress will likely provide enough support to keep your spine aligned while still offering some contour for pressure relief. However, as a side sleeper, you may experience some pressure points, particularly on your shoulders and hips, if the mattress is too firm. If you find that to be the case, you could consider a softer version of the mattress or add a soft topper.
Toppers can be a great addition for a mattress and serve a dual purpose. A topper can add needed pressure relief and contouring that some firm mattresses may not provide. Additionally, a topper can extend the life of the mattress as it is the first layer that absorbs the force of the body and will be exposed to the normal wear and tear of a mattress system. They can then be replaced multiple times during the course of the life of the mattress will be longer than if the mattress had not had a topper being used in combination.
Durability can be a concern with any mattress, and while the salesperson confirmed the mattress is made in the USA, it is not unusual to find some reviews that will offer mixed results. The fact that it is made in the USA usually will indicate a more consistent manufacturing process, and quality control, but the bottom line is the quality of the foams being used will dictate durability and longevity.
Memory foam and hybrid mattresses, in general, can be long-lasting, but quality does vary, and some users have reported sagging or diminished support after several years. Sometimes, this can be due to the construction and materials used in the mattress and other times it can be due to a mismatch of mattress to the user.
To gauge how the mattress holds up, some will consider the warranty, as MLILY offers a 10-year warranty on many of their models, which suggests a reasonable expectation of longevity. You can also explore user reviews over time to identify any recurring issues. Additionally, the return policy or trial period will be important. Many mattress brands offer a trial period where you can test the mattress at home for periods of 30 days to a year, which would give you time to assess whether it works well for you in the long run.
Ultimately, if you are confident it this or any mattress, remember your 4 R’s (Refund, Return, Restocking fee, Reputation/Reviews —off site reviews such as those on reddit, here at TMU, or on the web, but not so much, the manufacturers or online review sites.)
No one can predict how long a mattress may last for a particular user, but the density of the foams, construction of the mattress, existence of lower quality foams within the mattress may offer some clues.
Hope this helps,
Maverick
