Product Overview
California Design Den sells this strictly as a Twin XL fitted sheet, not a set, with the listing explicitly noting no flat sheet and no pillowcases are included. The sheet measures 39 inches wide by 80 inches long and uses 15 inch deep pockets with all-around elastic, built for mattresses with a topper that pushes past standard depth.
Material is 100% long-staple cotton woven in a 400 thread count sateen, which the listing describes as giving a smooth glide and a subtle sheen with a polished look. The product carries a Good Housekeeping Seal, which the listing notes is only awarded after the Institute's own lab evaluation, plus OEKO-TEX Standard 100 certification confirming it passed safety testing for harmful substances.
Score Breakdown
This verdict is based on the manufacturer's stated specifications, the current Amazon listing and its product images, the confirmed materials and design, real buyer ratings, and our research into the product category. Scores are consistent editorial judgments, not laboratory measurements, and we did not receive a paid sample.
Key Features
100% long-staple cotton woven for a smooth glide and subtle sheen.
All-around elastic pockets fit mattresses with a topper added.
Awarded only after the Institute's own lab evaluation of the product.
Confirms the fabric passed safety testing for harmful substances.
Top and bottom tags show which way the sheet goes on the mattress.
Tested for pilling, fading and shrinkage per the listing.
Design and Build Quality
Construction is 100% long-staple cotton in a 400 thread count sateen weave, a balanced everyday weight according to the listing rather than an unusually heavy or light fabric. Dimensions are 39 inches wide by 80 inches long with 15 inch deep pockets, and top and bottom tags mark orientation to help get the sheet on the right way.
The sheet weighs 1.7 pounds and carries all-around elastic for a no-pop fit over a mattress, with the listing recommending buyers measure mattress height, including any topper, against the 15 inch pocket depth before ordering. Made in the brand's own family-owned factory, the listing states cotton bedding has been produced there for over 20 years.
Performance in Everyday Use
The sateen weave is built for a smooth glide and a subtle sheen rather than the drier, more matte hand of a percale weave, with the listing noting that screens and room lighting can shift how the Green Sage shade reads, appearing warmer or cooler depending on light. The 15 inch deep pockets with all-around elastic are built to maintain a no-pop fit, a detail that matters most on taller mattresses or mattresses with a topper.
Care is machine wash warm with tumble dry low, and the listing states the sheet is independently tested for pilling, fading and shrinkage, with bleach ruled out. The Good Housekeeping Seal and OEKO-TEX Standard 100 certification are both third party checks cited by the listing rather than the brand's own unverified claims.
How It Performs: The Evidence
| Decision factor | What we found | Evidence and measurement | Score | Why it matters |
|---|---|---|---|---|
| Fabric quality | 100% long-staple cotton, 400 thread count sateen | Listing states 100% long-staple cotton in a 400 thread count smooth sateen weave for a balanced everyday weight | 8.3 | A specific thread count and fiber type give a concrete basis for the fabric quality claim |
| Pocket depth and fit | 15 inch deep, all-around elastic pockets | Listing states the fitted sheet has all-around elastic and 15 inch deep pockets | 8.2 | A stated pocket depth confirms fit for mattresses with a topper |
| Third party certification | Good Housekeeping Seal awarded after lab evaluation | Listing states the Good Housekeeping Institute tests products in its own lab and a product earns the Seal only after evaluation | 8.5 | An explicit third party testing process supports treating the Seal as an independent check |
| Safety certification | OEKO-TEX Standard 100 certified | Listing states every item bearing the OEKO-TEX Standard 100 label is certified as having passed safety tests for harmful substances | 8.1 | A named certification standard supports the stated safety testing claim |
| Durability testing | Independently tested for pilling, fading and shrinkage | Listing states the sheet is independently tested for pilling, fading and shrinkage | 7.9 | An explicit durability testing claim supports confidence in long-term wear |
| Sheet weight | 1.7 lb | Listing item dimensions list weight as 1.7 pounds | 7.6 | A specific weight figure is consistent with a single-layer fitted sheet rather than a heavier set |
| Set composition | Fitted sheet only, no flat sheet or pillowcases | Listing states this is the Twin Extra Long fitted sheet only, not a set, with no flat sheet and no pillowcases | 6.9 | An explicit statement that this is sheet-only is a real planning point for a buyer expecting a full set |
Who Should Buy It
- Twin XL beds, including dorm rooms and adjustable frames
- Mattresses with a topper needing a deeper fitted pocket
- Buyers wanting a smooth sateen weave over a matte percale
- Buyers who already own a flat sheet and pillowcases and only need the fitted sheet
- Buyers wanting a crisp, matte percale weave, since this is a smooth sateen weave with a subtle sheen rather than a flat finish
- Sold as the fitted sheet only, so a flat sheet and pillowcases are separate purchases
- The sateen weave's sheen and screen lighting can make the Green Sage shade look different than expected
- Only the Twin XL size is covered by this specific listing
- Bleach is ruled out entirely by the care instructions
