Frequently Asked Questions
How deep is considered 'extra-deep' for fitted sheets?
Extra-deep generally means pocket depths of 16 inches or more. If you use a mattress topper or have a high-profile mattress, measure mattress height plus topper thickness and choose a sheet labeled for that combined depth (for very tall setups, look for 17–21" pockets).
Will microfiber deep-pocket sheets run hot for guests?
Brushed microfiber is soft and tends to trap more heat than lightweight cotton percale. Some microfiber sets, like the LuxClub option, are marketed with cooling construction and better breathability. If guests sleep hot, choose sets labeled for cooling or select a cotton or blend alternative.
How can I keep fitted sheets from slipping off a high mattress?
Pick fitted sheets with strong, all-around elastic and reinforced corners; ensure pocket depth matches mattress+toppers; tuck the corners firmly under the mattress edges; consider sheet straps or grippers for extra hold if necessary.
