The general rule is that the thicker the topper, the softer it feels. If your mattress is just a little firmer and you want to add some extra comfort, then the 5-cm topper will do the job for you. If the mattress is extremely firm and causes pain and stiffness, then the deeper 8-cm topper would be the better option. 

Some customers might prefer a thinner topper for a balance between support and cushioning, while others might opt for a thicker one for a more luxurious feel. In addition, the thickness of your topper should complement the overall height of your mattress to promote ease of getting in and out of bed.

We advise considering individual preferences first when choosing a topper's thickness. The ideal thickness depends on your personal needs and the condition of your current mattress, respectively. 

What is beneficial to one person might not be suitable for another. Therefore, for those sharing a bed with a partner, determining which topper thickness is most suitable for both of you is the fundamental approach to adequate comfort and restful sleep. Additionally, if two people have a substantial difference in preferences, then they can each choose a topper in a different depth to meet their individual needs. However, please bear in mind that placing two single toppers with different heights will cause one side of the bed to rise higher than the other. 

According to UK standard bed sizes, all King and Super King toppers can be made of two singles pushed together. If you purchase two long small single size toppers that measure 75cm wide by 200cm long (2 ft 6 x 6 ft 6), they will make a king size bed, 150x200cm, (5 ft x 6 ft 6). Two European single size toppers that measure 90cm wide by 200cm long (3 ft x 6 ft 6) and are pushed together will be the exact same size as a super king bed, 180x200cm, (6 ft x 6 ft 6).
