100% Viscose Bamboo Sheets King - Extra Deep Pocket Cooling Luxury

In this review of the SONORO KATE 100% viscose bamboo sheet set, the bottom line is simple: these sheets are for sleepers who want a silky, cooling feel and need fitted sheets that genuinely fit very deep mattresses. The reviewer found the fabric exceptionally smooth and noticeably cooler than regular cotton, and the fitted sheet's 18'-24' extra-deep pocket made it an obvious choice for thick pillow-top or memory foam mattresses. If you value hotel-style softness and moisture-wicking performance, this set deserves serious consideration.

Key Features

• 100% bamboo-derived viscose: provides an unusually thick, silky-smooth surface that feels luxurious against skin and improves sleep comfort.
• Cooling and moisture-wicking: the bamboo fabric moves moisture away faster than cotton, helping hot sleepers stay drier and cooler at night.
• Extra deep pocket fit: the fitted sheet accommodates mattresses from 18' to 24' deep with a 360 elastic band that secures the sheet on tall or pillow-top mattresses.
• Complete 4-piece king set: includes one flat sheet, one fitted sheet, and two pillowcases sized for a king bed and standard king pillows.
• Easy care and durable: retains color and resists wrinkles and stains, and can be machine washed cold and tumble dried low without ironing.

Who It's For

This set is best for hot sleepers who prefer a silky, hotel-like sheet and for owners of thick mattresses such as memory foam, euro-top, or models with mattress pads who regularly struggle to find fitted sheets that stay on. The cooling, moisture-wicking fabric also makes it a good year-round option for people who overheat at night.

Shoppers who want crisp, high-thread-count cotton feel or who need a firmer, less slippery surface might look elsewhere, since the viscose from bamboo has a distinctly smooth, almost satiny hand. Also, if you need ultra-tight corner grip for very active sleepers, note that customer feedback on mattress stay is mixed.

Pros & Cons

Pros

• Exceptional softness and a silk-like texture that many reviewers compared to luxury hotel bedding.
• Effective cooling and moisture-wicking performance that helps manage nighttime heat and sweat.
• Fits very deep mattresses (18'-24') and works with pillow-tops, mattress pads, and memory foam.
• Low-maintenance care: resists wrinkles and fades and is machine washable and dryer safe.

Cons

• Some users report the fitted sheet can slide on certain mattress and topper combinations, so results vary by mattress surface.
• The silky hand may be too smooth for sleepers who prefer a crisp cotton feel.
