Summary: Our testers for our Molecule CopperWELL Mattress Topper review loved the superb temperature regulation of this 3" medium-firm mattress topper, scoring it a 5 out of 5 for temperature control. The cooling properties come from the breathable open-cell design and copper-infused memory foam, and none of our testers experience any heat retention from the Molecule mattress topper while sleeping on it. Side sleepers will also love the zoned support and pressure relief of its memory foam build, but keep in mind that the topper doesn't come with a cover and may not be firm enough for stomach sleepers.
Price history: There's hardly ever a discount on the CopperWELL topper at Molecule, you'd have to shop at a third party retailer to find a deal. The last deal we saw was a 25% back-to-school sale, where a queen-size was $187.50 and a twin XL is $135 (was $179.99).
Benefits: 30-night trial | 5-year warranty | Free shipping
Are mattress toppers worth it?
Mattress toppers are worth it - provided you buy the right one for your mattress, sleep issue, budget, and sleep position. We reccomend a topper that's between two to four inches thick (anything thinner will have no impact on your bed and anything taller will be too squidgy).
Hot sleepers should go for latex mattress toppers (which are naturally breathable) or the best memory foam mattress toppers that have cooling features such as perforated foam or copper gel infusions. Also, remember to check that a bed topper comes with a sleep trial before buying, that way you can test it out before committing to your purchase.
