That sounds really frustrating, especially since you were sleeping comfortably before. Based on what you described—pressure building in your ribcage and side after a short time—it may not be about going softer or firmer, but rather how the mattress distributes weight and supports your body. As a lighter (130 lb) side sleeper, you need something that both relieves pressure at your shoulders and ribs and keeps your spine aligned. Our Back Science mattresses are designed with that in mind, using Hypergel—a more buoyant and responsive material than traditional memory foam—so you stay lifted while still getting cushioning at pressure points instead of sinking in unevenly. We also use zoned support, with more give under the shoulders and more support through the hips and midsection, to help maintain proper alignment without forcing you into a firmer feel.
We also know comfort is highly individual, which is why we offer a 365-night sleep trial that includes the ability to modify the mattress if needed. Rather than being locked into one feel, we can work with you to fine-tune the comfort and support so it better matches your body and sleeping style. And for long-term peace of mind, our mattresses are backed by a 30-year limited warranty, designed to ensure they maintain their structure and support over time. Together, that gives you the flexibility to get it right now and the confidence that it will continue to perform well for years to come.
