California King Sheet Set - Breathable 1800 Supreme Luxury Sheets

Our review of the California King Sheet Set from the 1800 Supreme Collection finds these sheets best suited for sleepers who want soft, low-maintenance bedding that stays in place. The single biggest reason to consider this set is the built-in elastic corner straps on the fitted sheet, which consistently keep the sheet secure on extra deep mattresses while delivering a noticeably soft, brushed microfiber feel that improves with each wash.

Key Features

• Material: 100% fine double brushed microfiber gives a smooth, soft surface that feels luxurious without a high price tag.
• Built-in Elastic Corners: Elastic corners and secure sheet straps keep the fitted sheet anchored to the mattress so it does not slip off during the night.
• Deep Pocket Design: Extra deep pockets and thick elastic allow the fitted sheet to accommodate taller mattresses and toppers for a snug fit.
• Complete Set: Each set includes one fitted sheet, one flat sheet, and two pillowcases (one pillowcase for twin sizes), covering all basic bedding needs out of the package.
• Easy Care: The microfiber construction is machine washable and tumble dry friendly, which helps the sheets stay cleaner longer with simple care.

Who It's For

These sheets are a good match for people who prioritize softness and a secure fit: sleepers with extra deep mattresses, those who dislike constantly re-tucking fitted sheets, and buyers seeking value without sacrificing comfort. The breathable brushed microfiber works well year-round for many users, offering a cozy surface that becomes softer after repeated washes.

Shoppers seeking natural fibers like pure cotton or linen, or those who require very high temperature performance or specific organic certifications, should look elsewhere. Also, buyers wanting multiple decorative layers or quilted toppers included should consider bedding sets geared toward layered ensembles instead of this straightforward sheet set.

Pros & Cons

Pros

• Very soft double brushed microfiber that gets softer with each wash.
• Secure built-in elastic corner straps prevent the fitted sheet from slipping off.
• Extra deep pockets and thick elastic provide a reliable fit on taller mattresses.

Cons

• Microfiber is not a natural fiber, so those preferring cotton or linen textures may not prefer the feel.
• Only basic bedding pieces included; no duvet cover or decorative shams are part of the set.
