This fitted cot sheet is sized for 31″ x 75″ mattresses, ideal for narrow twin sleepers, camping cots, RV bunks, or guest beds. The sheet uses a high-quality microfiber that is breathable, stretchy, and silky soft, providing a cool, comfortable sleeping surface. An elastic band encases the bottom edge to keep the sheet in place all night, preventing slipping, wrinkling, or pulling away from the mattress.

It features breathable, soft microfiber with an all-around elastic band to prevent shifting. The result is a smooth, secure surface that remains comfortable through nightly use and travel.
Breling Fitted Sheet – Milliard Trifold Compatible

The Breling fitted sheet is sold as a sheet-only option for the Milliard Tri Folding Mattress.

Coldwind’s cot sheets offer a snug 31″ x 75″ fit with deep pockets designed to accommodate mattresses up to 9 inches deep. The ultra-soft microfiber surface is gentle on sensitive skin and suitable for kid-friendly bedding. The elastic bottom band keeps the sheet from riding up, delivering a smooth, secure sleeping surface across varied 9-inch or narrower cot mattresses.
Utopia Bedding Flat Sheet – Twin Grey

While primarily a flat sheet, its twin size variant offers a soft, brushed microfiber fabric with a 2-inch hem and fade resistance. This option pairs well with fitted sheets for twin-sized setups, including small, portable beds where a complete sheet set may be preferred for ease of care and long-lasting use.
Breling Fitted Sheet – Light Gray

This Breling fitted sheet mirrors the Milliard compatibility style but in a lighter gray. With the same all-around elastic band design and microfiber construction, it delivers a secure, snug fit for single, 75 x 25 x 4 inch mattresses. It’s suitable for travel or home use and supports repeated washing without sacrificing fabric integrity.
Milliard Trifold Mattress Fitted Sheet

Specifically designed for the Milliard 4-inch trifold mattress, this fitted sheet is soft, durable, and machine washable. The fabric remains stretchy under use, and the elastic construction ensures the sheet stays neat and tight on the mattress, even with frequent folding and unfolding typical of trifold setups.
Vonty 1Pcs White Cot Sheets – 31″ x 75″

Vonty’s cot sheets emphasize a plush 1800 thread count microfiber surface for enhanced softness and breathability. They are designed for narrow twin or camp cot mattresses, with deep pockets and a reinforced elastic band to keep the sheet secured throughout the night. This model aims to deliver a premium feel on portable bedding environments.
Buying Guide: Key Considerations For Small Single Bed Sheets
- Mattress compatibility: Confirm mattress dimensions (width, length, and depth). Narrow twin and 4″ folding mattresses are common targets for these sheets; look for explicit depth compatibility (often 4″ or up to 9–10″ in some models).
- Fit and retention: An all-around elastic band or bottom-edge elastic band improves sheet stay-put performance, reducing slipping and wrinkling during sleep.
- Material quality: Microfiber blends around 90–1800 thread count determine softness, breathability, and durability. Higher thread counts can feel smoother but ensure they’re truly breathable and not just tightly woven.
- Care and durability: Machine-washable sheets with colorfast and shrinkage-resistant finishes extend their usable life, especially for travel bedding that experiences frequent washing.
- Fit for travel vs. home use: If you travel often, prioritize elasticized edges and deep pockets for a secure fit on various portable beds. For home guest rooms, compatibility with tri-fold mattresses can be a plus.
- Allergen considerations: Look for hypoallergenic microfiber options if sensitive skin is a concern. Breathable fabrics help maintain a cooler sleeping environment for restless sleepers.
- Color and aesthetics: Neutral colors like white, gray, or soft tones blend with most bedding ensembles and are easy to launder without noticeable wear.
- Maintenance compatibility: Check if the sheet materials tolerate frequent washing and drying without pilling or losing elasticity over time.
- Value vs. duration: Compare not only price but also elasticity, fabric recovery after washing, and the likelihood of frequent replacement in high-use settings like camps or dorms.
