Layer 3 of 5, counting up from the mattress
Sheets
Sheets are the layer you actually touch all night, and the only one in the stack that has to grip something. A flat sheet and pillowcases are cloth rectangles and behave like it. A fitted sheet is a piece of engineering with elastic in it, and it is the item in a linen closet that gets sent back most often.
Where it sits
Fit
Does it fit?
Pocket depth is the distance from the seam at the top corner down to where the elastic gathers, and it is the number that decides whether a fitted sheet stays on. It has to cover the mattress, plus anything you have added on top of the mattress, plus enough left over to turn under. A pocket that exactly equals your stack height is a pocket that will be off one corner by morning. Two things make this harder than it should be. Manufacturers do not all measure the same way, and several of the sheet listings in this catalog do not state a pocket depth at all. Where a listing does not state it, this site records nothing rather than guessing.
- Stated pocket depths across the sheet listings in this catalog: 12 in, 14 in, 15 in and 16 in.
- One listing states a span instead of a single figure: 6 to 15 in.
- One listing states a 12 in pocket and separately says it fits up to a 14 in mattress, which is the clearest illustration on this site that the two numbers are not the same measurement.
Heat
Does it sleep hot?
Weave does more here than fiber name does. Percale is a plain over-under weave and it feels crisp and dry. Sateen floats more threads on the surface, which is what makes it look faintly polished and feel heavier. Between two cotton sheets, that difference is the one you will notice. Thread count is a count of threads in a square inch, and it stopped being a useful signal once manufacturers began counting plies. A 400 thread count sateen and a 400 thread count something else are not comparable, and the number tells you nothing at all when the listing has not said what the fiber is.
Words sellers use on this layer
- cooling
- breathable
- crisp
- silky
- wrinkle-free
None of those carries a unit or a test method. They describe an intention, and this site quotes them as seller language wherever they appear on a listing.
Wash
How often does it go in?
- How often
- Weekly for the sheet you sleep on, and weekly for pillowcases.
- Watch for
- Pilling, which shows up first where a forearm rubs. Short staple fibers work loose and ball up.
- Elastic gone slack at one corner, usually the corner nearest the wall that gets pulled hardest.
- Thinning at the foot of the flat sheet, which is where heels do the damage.
- Replace when
- When the fitted sheet no longer holds a corner through a night, or when a thin patch has become a hole. A set that is pilling badly is unpleasant long before it is worn through, and that is a reasonable reason on its own.
The whole schedule, with every prohibition in one place, is on Care Calendar.

One concrete example
Fitting the corner and stating what the fabric is is what this category has to do, and this is the item in it whose listing states the most about doing that. The rest of the 12 are on Sheet & Pillowcase Sets.
California Design Den Cotton Sateen Sheets, Queen
Deepest pocket that also states its elastic
This is the one listing in the sheet section that answers both halves of the question at once: it names the fiber outright and it puts a number on the pocket. Sixteen inches is the deepest stated pocket here, though two other sets match it. What separates this one is that it also states elastic all around, which is the construction that keeps a deep pocket from riding up on a shallow mattress.

- Cotton Percale
Percale is cotton in a plain weave: one thread over, one thread under, evenly, all the way across. That is the entire definition. It is not a quality tier and it is not a brand, and any cotton fabric woven that way can be sold under the word. What the structure gives you is a matte surface with no sheen and a hand that people describe as crisp, which is really just a fabric with nothing floating loose on the face of it.
- Cotton Sateen
Sateen is cotton woven so that several threads float across the surface before being tied down, instead of interlacing every single time. Those floats catch light, which is where the faint sheen comes from, and they present more unbroken yarn to your skin, which is where the heavier and smoother hand comes from. It is the same fiber as percale doing a different job because it was threaded differently.
- Microfiber
Microfiber is polyester, extruded as filaments fine enough that the fabric behaves differently from ordinary polyester cloth. The word describes the fineness of the fiber, not the fiber itself, so a microfiber sheet is a polyester sheet with a specific manufacturing spec. Listings use the texture word far more often than they use the fiber word, and both are accurate.
- Rayon and Viscose from Bamboo
This is rayon. Bamboo is the plant the cellulose was taken from, and the fabric that results is a regenerated cellulose fiber, not bamboo in any structural sense. The FTC has been explicit that textiles made through the viscose process have to be labeled as rayon or as viscose, with bamboo mentioned only as the source of the raw material. Listings that say bamboo alone are not describing what is in the box.
- Satin Weave
Satin is a weave in which long floats run across the surface with very few tie-down points, producing the highest shine of any common construction. It says nothing about what the threads are made of. Silk satin, polyester satin and nylon satin are all satin. In bedding the fabric is most often a polyester filament, because filament is what holds that particular shine, but that is a general fact about the category and not a statement about any specific set. The one satin listing in this catalog names the weave and does not name the fiber, so this site records the fiber as unstated.
