Is an expensive topper worth it over a budget one?

It depends on durability and support needs. Budget toppers like the Niagara and Best Price models earn praise for value across tens of thousands of reviews, but community feedback notes they compress over time. Premium copper-infused and tested toppers cost far more and draw stronger durability and support praise from specialist publishers, though even high-trust sources describe some premium cooling as 'temperature-neutral' rather than dramatically cold.
