The most obvious difference is height. The Flip Topper is 5cm while the Premium Topper is 8cm. The Flip Topper is a reversible topper in the entry-level price range, with two lying sides of different firmness. The benefit for you is that you can turn the topper at any time and adjust it to your needs or preferences. The different layers of Airgocell foam and HRX foam guarantee either a soft or firmer lying position. The Premium Topper is a topper with a layer consisting of millions of tiny graphite particles that help you reach the ideal sleeping temperature in record time. Comparing the two toppers, the Premium Topper is more supportive and gives enough room to adapt to different body types and sleeping positions. As an added bonus, the underside of the Premium Topper is also equipped with an anti-slip coating.
