ROYAL BLISS Split King Royal Collection 1900 Sheets - Ultra-Soft Navy

Our review of the ROYAL BLISS Split King Royal Collection 1900 sheet set finds it best suited for sleepers who prioritize a soft, lightweight feel and a fitted sheet that stays put. The single biggest reason to buy is the proprietary hydro-brushed fabric, which creates an unmistakably soft, airy surface that keeps sleepers comfortable across seasons. In practical terms this set is a strong pick for anyone with a Flex King or split-top mattress who wants deep pockets and all-around elastic to prevent sliding during the night.

Key Features

• Hydro-brushed fabric: The microfiber yarn is treated to deliver an ultra-soft, lightweight hand that feels cooling in summer and cozy in winter.
• Split head fitted sheet: The 36in split top fitted sheet accommodates Flex King or adjustable split mattresses for independent head adjustment.
• All-around elastic: Elastic runs around the entire fitted sheet so it grips the mattress and resists coming loose overnight.
• Extra deep pockets: The fitted sheet has a 16in pocket depth to fit thicker mattresses and mattress toppers without popping off.
• Complete set dimensions: Includes one king flat (108in x 102in) and two king pillowcases (20in x 40in) to fully outfit a king bed.

Who It's For

The set is ideal for owners of split-top or Flex King beds, adjustable beds, and Sleep Number-style systems where each side needs independent head movement. The lightweight hydro-brushed fabric is a good choice for those who want a soft, breathable sheet that feels like a light layer rather than a heavy sateen.

Shoppers who prefer a substantial, thick cotton percale may want to look elsewhere because several customers noted the material reads as thin. If long-term heavyweight durability or a natural fiber like 100% Egyptian cotton is a strict requirement, this microfiber hydro-brushed set may not match those expectations.

Pros & Cons

Pros

• Exceptional softness from the hydro-brushed microfiber for immediate comfort.
• Designed for Flex King use with a 36in split and correct flat sheet and pillowcase sizing.
• All-around elastic and 16in pockets keep the fitted sheet secure on deeper mattresses.
• Lightweight construction that stays cool and is easy to launder.

Cons

• Material is relatively thin compared with heavier sheet fabrics, which some users called less substantial.
