King Mattresses

king size bed and ensemble

Sleep in the starfish position? Have plenty a spacious bedroom? A King Mattress could be the ideal selection for you!

King Mattresses are perfect for couples who like their own sleeping space, for families and pets who cuddle in bed, for pregnant women, or for those with injuries who need the space to spread out. If it is for your guest bedroom, you can be assured that your guests sleep healthy and wake up feeling amazing, every morning during their stay. Warning, they might not want to go home!

Whether it is for yourself, for you and your partner or even for your guests, you will not be disappointed with the luxury and comfort a King Mattress provides.

King Mattress Dimensions

At 183cm x 204cm, King Mattresses are extremely spacious. They provide restful recovery for pregnant women or those who are injured, as well as ensuring an amazing night’s sleep.
