The recommendation engine compares available catalog information with your profile. It considers fit factors such as estimated compressed height, firmness, supported positions, adjustability, and relevant restrictions. Affiliate status is not a scoring factor. You can look past the ranking and read the reasons that produced it.
Use that shortlist as a shopping companion. Confirm the exact variant and current specifications with the manufacturer, especially when a range includes different heights or sizes. Review materials, care instructions, trial terms, and returns before you buy. Product information and availability can change, and a good comparison includes those practical details.
The catalog is a starting selection, not every pillow on the market. If your restrictions leave no suitable match, the app can explain the gap instead of forcing a recommendation. That is useful information too: you may need a different option, more precise measurements, or guidance that goes beyond the current catalog.
