SGI bedding 28 in Cal King Split Top Flex Head Sheet Set - Adjustable

In this review of the SGI bedding 28 in Cal King Split Top Flex Head Sheet Set the bottom line is simple: this set is built for adjustable beds and delivers the most value when you need a fitted sheet that accommodates a top split head. Reviewers and testers will appreciate the tailored fit for split top flex head bases and the soft, bio-polished cotton that improves with washing, making it a practical choice for couples who adjust each side independently.

Key Features

• Split top design: The fitted sheet has a 28 in split from the top so each side of a top split adjustable bed can raise independently without binding or riding up.
• Complete four-piece set: Includes one split flex Cal-King fitted sheet, one Cal-King flat sheet and two king pillowcases to cover all standard bedding needs for a Cal-King adjustable setup.
• Quality yarn and weave: Made from long staple yarns and advanced weaving techniques for improved durability and a soft hand that stands up to repeated washing.
• Fully elasticized fit: Elastic around the entire fitted sheet provides a secure hold on mattresses up to 15 in deep, reducing shifting on Sleep Number and similar beds.
• Bio-polished finish: The finishing process gives a cooling, smooth surface that feels softer after a few washes and resists initial fuzz.
• Easy care: Machine wash warm and tumble dry low with gentle handling recommended to preserve the seams and color.

Who It's For

This sheet set is ideal for owners of split top adjustable beds, couples who need independent head adjustments, and anyone using a Cal-King mattress with up to 15 in depth. The set's split 28 in top and fully elasticized skirt make it a practical, low-fuss solution for adjustable platforms and Sleep Number style systems.

Shoppers seeking ultra-luxury sateen or buttery microfiber finishes might look elsewhere; while the cotton is soft and durable, a few users noted the hand feel varies and seams can be vulnerable if laundered roughly. If you need very delicate finish or non-cotton performance fabrics, consider other materials.
