Best Mattresses

Each Mattresses in this list was assessed using our published Mattresses review framework. Our assessment covers:

• Specification transparency. We document conflicts between product title, feature bullets, and specification table claims. Units with unresolvable contradictions receive lower evidence confidence scores.
• UK mains compatibility. All reviewed units are assessed for 230V/50Hz UK plug compatibility.
• Capacity and features. We verify stated basket capacity, drawer configuration (single vs dual zone), and cooking modes against the manufacturer specification.
• Running cost estimate. Where published wattage figures allow it, we calculate an indicative running cost at the current UK unit rate of approximately 24p/kWh.

All current models in our review set are rated Needs Verification — meaning evidence comes from manufacturer-published specifications only. We will update confidence ratings as independent testing data becomes available.
