I slept on Ikea's Nisseholm mattress topper for a week – this is why I think it's the best firm topper on the market

The IKEA NISSEHOLM mattress topper being tested over a mattress.

For this Ikea Nisseholm mattress topper review, I put the brand's firmest mattress topper to the test to see how it performed, and I was impressed.

The Ideal Home team has tested a whole host of mattress pads to find the best mattress toppers on the market, but the one thing we had (until this point) struggled to find was a good firm mattress topper.
