FAQ

  • How big is a split king size mattress?

    The same size as a king size mattress (76” by 80”), a split king is made up of two twin XL mattresses that each measure 38 inches in width by 80 inches in length.

  • What is the difference between a split king mattress and a king size mattress?

    Though both king and split king mattresses have identical lengths and widths, a split king is two twin XL mattresses side-by-side whereas a king size mattress is one single mattress.

  • Which is the best split king size mattress?

    Sleepers who are looking for a versatile split king size mattress for both temperature regulation and steady support can’t go wrong with the bestselling Puffy Lux Hybrid. The combination of plush foam with sturdy coils makes this the ideal choice for sleepers with back pain or chronic aches. For sleepers who prefer an ultra-plush feel, the Puffy Royal Hybrid is an ideal choice. If an all-foam mattress with a medium-firm feel is what you’re after, the award-winning Puffy Cloud Mattress is also ideal.
