Choosing the best baby sheets for a bassinet starts with getting the fit right: a sheet should match the mattress dimensions and stay snug around its edges. The five options below offer different sizes, fabrics, and pack counts. Check your bassinet manual and measure its mattress before ordering, since sheets made for one size may not fit another securely.

Our Picks: Best Baby Sheets For Bassinet reviews
Biloban 4-Pack: A Practical Pick for 33 x 20-Inch Mattresses
Biloban’s four-sheet set is designed for mattresses measuring about 33 x 20 inches. The product description names Baby Delight, Semphis, Mika Micky, and Dream On Me models among its intended matches. That size makes it a useful option for certain rectangular bedside sleepers, but it is not a universal fit for every bassinet.
The sheets are made from microfiber woven into a soft jersey fabric. A fully encased elastic edge is intended to make them easier to put on and remove than an envelope-style casing, while keeping the sheet around the mattress. The listing also describes the fabric as breathable and free of plastic, with no noisy crinkling.
Four sheets give you extras for laundry days or quick changes. Before buying, compare the mattress’s length, width, and thickness with the product dimensions. A similar-looking bassinet can still have a different mattress size, and a sheet that bunches or slips is not a good fit.
Pros:
- Four sheets in the set
- Designed for 33 x 20-inch mattresses
- Fully encased elastic edge
- Machine washable on a gentle, cold cycle
Cons:
- May not fit bassinets with smaller or differently shaped mattresses
- Microfiber may not suit shoppers who prefer natural fibers
Verdict: Choose Biloban if your bassinet mattress measures about 33 x 20 inches and you want a four-sheet microfiber set for regular changes.
IOCCLH 4-Pack: Stretchy Sheets for a Range of Bassinet Shapes
IOCCLH lists these fitted sheets at 32 x 16 inches, with a fit for mattresses up to 4 inches thick. The product description mentions hourglass, oval, rectangular, and round bassinets, as well as compatibility with Halo Bassinest. Shape alone does not guarantee a fit, so confirm that your mattress dimensions are within the stated size range.
The four-pack includes different prints and solid designs. The sheets use microfiber knit fabric and elastic around the edges, which the listing describes as designed for quick installation and removal. That can be handy when you need to swap a sheet during the night or keep a spare in your changing area.
Its listed width and length are smaller than the 33 x 20-inch options in this roundup. That distinction is important: stretching a smaller sheet over a larger mattress could affect how securely it fits. Measure first and check the mattress thickness, especially if your bassinet has a shaped or unusually deep pad.
Pros:
- Four sheets with a mix of prints and solids
- Elastic edges are designed for easy changes
- Listed for mattresses up to 4 inches thick
- Machine washable on a gentle, cold cycle
Cons:
- The 32 x 16-inch size will not match every bassinet
- Broad shape compatibility still depends on the mattress measurements
Verdict: This set is worth considering if your mattress measures 32 x 16 inches or is confirmed to fit its listed dimensions and thickness.
GLLQUEN BABY 4-Pack: A 33 x 20-Inch Set with OEKO-TEX Labeling
GLLQUEN BABY’s four-pack is tailored for 33 x 20-inch bedside sleeper mattresses. Its product information also describes the sheets as suitable for similarly sized oval or rectangular bassinets. The stated size is the key detail to check; a similar shape does not mean a different-sized mattress will fit securely.
The fabric is 100% microfiber polyester, and the listing identifies it as OEKO-TEX STANDARD 100 certified. It also describes a full-coverage elastic band and says the material is made to withstand repeated washing. A gift-ready box and floral pattern are extra touches, though the practical value will depend most on fit and your preferred fabric.
Compared with the other 33 x 20-inch set here, this option makes its OEKO-TEX labeling a central feature. If that matters to you, check the product listing for certification details before ordering. The set is still microfiber, not cotton, so it may not be the right choice if you are specifically seeking a natural-fiber sheet.
Pros:
- Four sheets for a 33 x 20-inch mattress
- Full-coverage elastic edge
- Listing identifies the fabric as OEKO-TEX STANDARD 100 certified
- Machine washable, according to the product description
Cons:
- Size may not suit smaller bassinet mattresses
- Made from microfiber polyester rather than cotton
Verdict: Consider this set if you need 33 x 20-inch sheets and value the OEKO-TEX labeling described in the product information.
Knirose 2-Pack: Muslin Cotton Sheets for Parents Who Prefer Cotton
Knirose takes a different approach from the microfiber sets: these sheets are described as muslin made from GOTS-certified organic cotton. The set includes two sheets and measures 33 x 17 inches, with a 6.5-inch pocket. The product description lists several mattress shapes and sizes, but the specified dimensions should guide your choice.
A fully encased elastic band runs around the sheet, and the listing says the fabric is machine washable. The set pairs a teddy bear print with a solid option. Cotton muslin may appeal if you are looking for a material other than polyester, but the smaller pack means fewer spare sheets than the four-pack options.
The product description makes broad claims about fit across bassinets, loungers, cradles, and co-sleepers. Do not rely on those labels alone: compare your mattress measurements and confirm the manufacturer allows that type of sheet. A sheet designed for a bassinet mattress should not be used in place of the mattress or as a loose layer.
Pros:
- Made from muslin cotton, as described in the listing
- Fully encased elastic edge
- 6.5-inch pocket is specified
- Machine washable
Cons:
- Two sheets per set, fewer than the other options here
- The 33 x 17-inch size will not fit every bassinet mattress
Verdict: Pick Knirose if you prefer a cotton muslin option and your mattress dimensions match the listed 33 x 17-inch size.
Unnivoll 3-Pack: A Compact Set for 32 x 16-Inch Mattresses
Unnivoll’s three-sheet set is made for mattresses measuring 32 x 16 inches. The product description says it can fit several mattress shapes, including oval, round, rectangular, and hourglass designs, and lists a 5-inch pocket. As with any fitted sheet, check the actual mattress measurements rather than choosing by shape alone.
The sheets are made of microfiber and have four-way elastic around the edge. The listing also describes them as pre-shrunk and machine washable. Three sheets offer a middle ground between the two-sheet Knirose set and the four-sheet options, though the right pack size depends on how often you do laundry and how many spare sheets you want.
Unnivoll’s dimensions are close to IOCCLH’s listed 32 x 16-inch size, but its stated pocket is deeper at 5 inches. That may matter if your mattress is thicker, provided its length and width also match. The listing mentions CPSC-related certification; check the product information for details rather than treating that claim as a substitute for verifying fit or following safe-sleep guidance.
Pros:
- Three sheets in the set
- 32 x 16-inch size with a listed 5-inch pocket
- Four-way elastic design
- Machine washable, according to the product description
Cons:
- Will not fit a mattress with substantially different dimensions
- Microfiber may not suit shoppers seeking cotton
Verdict: Unnivoll is a sensible option if your bassinet mattress measures 32 x 16 inches and you want three microfiber sheets with a deeper listed pocket.
How to Choose Bassinet Sheets
Measure the Mattress, Not Just the Bassinet
Measure the mattress’s length, width, and thickness, then compare those numbers with the sheet’s listed dimensions and pocket depth. Bassinets can look similar but use different mattress sizes. If the mattress is oval or hourglass-shaped, check the manufacturer’s fit guidance as well as the measurements; a sheet that fits a rectangle of similar dimensions may not fit every contour.
Choose a Snug Fitted Design
Look for a fitted sheet with elastic that holds it securely around the mattress. Follow the bassinet maker’s instructions for approved sheets, and check the fit whenever you change or wash one. Do not use a sheet that slips, bunches, or leaves loose fabric on the sleep surface.
Compare Fabric Types
The options here include microfiber and cotton muslin. Microfiber is the material used in most of these sets, while the Knirose sheets are described as GOTS-certified organic cotton muslin. Fabric choice is personal, but it should not replace checking the dimensions, fit, and care instructions.
Think About Pack Size and Laundry
A larger pack gives you more clean sheets to rotate while others are in the wash. The choices here range from two sheets to four. Consider how often you expect to change sheets and how frequently you do laundry, but do not choose a larger set if its size does not match your mattress.
Check Washing Instructions
Each product description gives its own care guidance. Several recommend a gentle, cold machine wash and low-heat tumble drying; follow the directions for the specific set you choose. Avoid bleach, ironing, or dry cleaning when the product instructions advise against them.
Keep the Sleep Space Simple
Use the sheet only as a fitted cover for the bassinet mattress. For sleep, follow the bassinet manufacturer’s instructions and current safe-sleep guidance: keep the sleep surface firm and flat, and do not add loose blankets, pillows, toys, or extra padding.
Frequently Asked Questions
How do I know what size bassinet sheet to buy?
Measure the mattress’s length, width, and thickness, then compare those measurements with the sheet’s stated size and pocket depth. Also check the bassinet maker’s guidance for approved sheets, particularly if the mattress is not rectangular.
Can one bassinet sheet fit oval, round, and rectangular mattresses?
Some product listings describe their sheets as compatible with several shapes, but shape is only one part of fit. A sheet still needs to match the mattress dimensions and stay securely in place. Confirm fit with the product details and your bassinet instructions.
Are microfiber bassinet sheets different from cotton muslin sheets?
Yes. Microfiber and cotton muslin are different fabrics. The products in this roundup include both options, so check the material description if you have a fabric preference. Either way, prioritize a secure fit and follow the care label.
How many bassinet sheets do I need?
That depends on how often you do laundry and how quickly you want a clean sheet ready after a change. A two-sheet set provides a basic rotation, while a three- or four-sheet set gives you more spares. Fit should come before pack size.
Can I use a bassinet sheet on a changing pad?
One product description mentions use on similarly sized changing pads, but that does not mean every bassinet sheet is suitable for every pad. Check the changing pad maker’s instructions and the sheet dimensions, and never use a loose or poorly fitting cover.
Should I add a blanket or mattress pad over the sheet?
Do not add loose bedding or extra padding to a bassinet sleep surface. Use only the mattress and fitted sheet approved by the bassinet manufacturer, and follow safe-sleep guidance.
Conclusion
The best choice depends on your bassinet mattress size and fabric preference. Biloban and GLLQUEN BABY are the options to compare for a 33 x 20-inch mattress, while IOCCLH and Unnivoll are listed for 32 x 16-inch mattresses. Knirose stands out for its cotton muslin construction and 33 x 17-inch size. Measure first, confirm the fit, and use only a snug fitted sheet on the bassinet mattress.
