How we compared cotton bassinet sheets

The best cotton bassinet sheets make the weave, care and dimensions easy to compare. We looked at stated fabric types, sheet counts, measurements, elastic details and washing guidance.

Fit comes first. A 33 x 17 in sheet won't fit every bassinet mattress just because its shape is oval or rectangular.

Measure your mattress, including depth, and compare each dimension with the sheet's stated size.

We also considered whether you prefer stretchy jersey knit or muslin. A fabric description can't tell you how a particular baby will respond to its feel, so choose based on the weave you prefer and the care routine you can manage.

For more general options beyond cotton, see our guide to the best baby bassinet sheets. If organic cotton is your priority, compare the best organic cotton bassinet sheets and best organic bassinet sheets.

Cotton bassinet sheets compared by fit and weave

The main differences are fabric construction, size and number of sheets per set. Check the measurements first, then use the weave and wash instructions to narrow your choice.

KeaBabies 2-pk Organic Baby Bassinet Sheets Boys: Best for stretchy organic cotton

9.7/10Our score

• 100% organic cotton
• 2 sheets
• 33 x 17 in
• Fits mattresses up to 4 in deep

The stretchy knit is designed to make fitting and removing the sheet easier. Its 33 x 17 in size and depth up to 4 in suit buyers whose mattress matches those measurements.

See it on Amazon

Pros

• Stretchy knit
• Hidden elastic band
• Machine washable and dryer friendly

Cons

• Confirm mattress dimensions and depth before buying

The KeaBabies Soothe sheet is a strong fit for shoppers who want stretchy organic cotton and a common 33 x 17 in size. The knit is designed to stretch during fitting and removal, and a hidden elastic band runs through the seams.

The set includes 2 sheets, each sized for mattresses up to 4 in deep. That stated depth matters: compare it with your mattress rather than assuming the length and width alone are enough.

KeaBabies describes the cotton as breathable and soft, and the sheets are machine washable and dryer friendly. If you prefer woven muslin, another pick in this roundup may suit your texture preference better.

Choose this set when your bassinet mattress measures close to 33 x 17 in and its depth is within the stated range. For other models, use the bassinet maker's bedding guidance and compare dimensions before buying.

KeaBabies 2pk Organic Baby Bassinet Sheets Boys: Best for a soft pink option

9.7/10Our score

• 100% organic cotton
• 2 sheets
• 33 x 17 in
• Fits mattresses up to 4 in deep

This KeaBabies set shares the stretchy cotton construction and 33 x 17 in dimensions of the other Soothe sheets. It gives you a soft pink color option.

See it on Amazon

Pros

• Stretchy knit
• Hidden elastic band
• Machine washable and dryer friendly

Cons

• Confirm mattress dimensions and depth before buying

This KeaBabies set shares the 33 x 17 in dimensions, organic cotton knit and 4 in maximum depth of the other Soothe options. Its Mist Rose color gives you a pink choice while keeping the same basic fit details.

The stretchy knit is intended to make sheet changes easier, and the hidden elastic band helps hold the sheet around the mattress. Machine washing and dryer use are both supported in the care details for this set.

Since the fit information matches the other KeaBabies picks, choose between them mainly by color. Measure the mattress first, especially if your bassinet uses a custom pad or a depth above 4 in.

If you're considering a bassinet with a canopy or hood, our guide explains what a bassinet hood is for. Keep bedding decisions separate from canopy use, and follow the bassinet's own safety instructions.

Gllquen Baby Muslin Bassinet Sheets 3pk: Best for a three-sheet rotation

9.6/10Our score

• 100% muslin cotton
• 3 sheets
• 33 x 17 in
• Machine washable

The 3-pack provides an extra sheet for changes between washes. Its 33 x 17 in dimensions and elastic band are designed for a range of mattress shapes.

See it on Amazon

Pros

• Three sheets in the set
• Muslin cotton
• Machine washable

Cons

• Check the mattress dimensions and depth against your bassinet

Gllquen's 3-pack suits families who want muslin cotton and a spare sheet ready. Each sheet measures 33 x 17 in, and the brand describes an elastic band for a snug fit across several mattress shapes.

The machine-washable fabric is described as light and breathable. The set's extra sheet can help when one is being washed, though you should still check the care directions and fit against your own bassinet mattress.

This size may work for mattresses near 33 x 17 in, but stated compatibility with several shapes doesn't replace measuring. Compare the length, width and mattress depth before choosing it.

KeaBabies 2pk Organic Baby Bassinet Sheets Boys: Best for a simple white set

9.5/10Our score

• 100% organic cotton
• 2 sheets
• 33 x 17 in
• Fits mattresses up to 4 in deep

This white KeaBabies set has the same stretchy cotton knit, size and depth guidance as the other Soothe sheets. Choose it when a plain white color suits your nursery.

See it on Amazon

Pros

• Stretchy knit
• Hidden elastic band
• Machine washable and dryer friendly

Cons

• Confirm mattress dimensions and depth before buying

The white KeaBabies set offers the same stretchy organic cotton construction and fit details as the other Soothe sheets. It measures 33 x 17 in and is intended for mattresses up to 4 in deep.

Its neutral color may work well if you want a plain sheet that pairs with different nursery patterns. The 2-pack also gives you a spare for laundry days, and the sheets can be machine washed and dried.

Choose it when the white color suits your setup and your mattress dimensions fall within the stated range. If you want a muslin weave, compare the Gllquen and LYRICHOM options instead.

5

Gllquen Baby 3-Pack Muslin Cotton Bassinet Sheets: Best for 33 x 20 in mattresses

9.4/10Our score

• 100% muslin cotton
• 3 sheets
• 33 x 20 in
• Fits mattresses up to 4 in deep

This muslin set is wider than the 33 x 17 in options, making its dimensions a potential match for a 33 x 20 in mattress. It includes three sheets and full elastic trim.

See it on Amazon

Pros

• Three sheets in the set
• Wider 33 x 20 in size
• Full elastic trim

Cons

• Not the same width as many common 33 x 20 in sheets

This Gllquen set is the wider muslin option, measuring 33 x 20 in with a stated pocket depth of up to 4 in. That extra width may suit a mattress that is wider than the 33 x 17 in size common among the other picks.

The 3-pack includes full elastic trim, and the sheets are machine washable. Muslin is a different construction from the KeaBabies knit, so compare both the feel you prefer and the dimensions your mattress needs.

Don't assume the wider sheet will fit a narrower pad securely. Measure the mattress and check the bassinet's guidance before choosing this set.

LYRICHOM BABY Muslin Bassinet Sheets 2 Pack: Best for 360-degree elastic

9.3/10Our score

• 100% muslin cotton
• 2 sheets
• 33 x 17 x 4 in
• Fully encased elastic

The fully encased 360-degree elastic and flexible fabric are designed to simplify fitting and removal. The 33 x 17 x 4 in measurements give you clear dimensions to compare with your mattress.

See it on Amazon

Pros

• Fully encased elastic
• Muslin cotton
• Machine washable

Cons

• Set includes two sheets

LYRICHOM combines 100% muslin cotton with a fully encased 360-degree elastic band. The 2-pack measures 33 x 17 x 4 in, offering a clear size reference for shoppers comparing standard bassinet pads.

The flexible fabric is intended to make fitting and removal easier. Machine washing is listed in the care instructions, while the muslin weave gives this set a different texture from the jersey-knit KeaBabies sheets.

Its dimensions may suit oval, rectangular or hourglass mattresses close to 33 x 17 x 4 in. Check the pad's actual measurements and avoid relying on shape labels alone.

7

Burt's Bees Baby 100% Organic Cotton Infant: Best for jersey knit

9.3/10Our score

• 100% organic cotton
• Jersey knit
• 2 sheets
• 33 x 15 in

The jersey knit offers a different cotton texture from muslin, and the 33 x 15 in size is narrower than many 33 x 17 in options. Check the mattress width before choosing it.

See it on Amazon

Pros

• Organic cotton jersey knit
• Two sheets
• 360-degree elastic

Cons

• Narrower 15 in width

Burt's Bees Baby is the jersey-knit option in a narrower 33 x 15 in size. Its organic cotton fabric and 360-degree elastic are designed to lie flat on standard oval or rectangular bassinet mattresses.

The 2-pack is machine washable, and the knit offers a different texture from muslin. Since the stated width is 15 in, compare it carefully with your mattress before buying, especially if your pad is 17 in wide.

This is a more suitable size to consider when your bassinet mattress is close to 33 x 15 in. Buyers looking for a 33 x 17 in sheet have several alternatives earlier in this roundup.

Blissful Diary Muslin Bassinet Sheets: Best for a checked pattern

9.1/10Our score

• Muslin cotton
• 2 sheets
• 32 x 17 in
• Machine washable

The 32 x 17 in sheets have a checked pattern and an elastic band around the bottom edge. Their shorter length may suit a mattress close to those measurements.

See it on Amazon

Pros

• Two-sheet set
• Checked pattern
• Machine washable

Cons

• Shorter 32 in length

Blissful Diary's muslin sheets stand out for a checked pattern and 32 x 17 in dimensions. That one-inch shorter length may matter if your mattress is closer to 32 in long than 33 in.

The set includes 2 sheets and has an elastic band around the bottom edge. Its care details describe machine washing, which can make routine sheet changes easier to manage.

Compare the 32 x 17 in size with your mattress before choosing it. If your mattress is 33 in long, check the fit guidance carefully instead of assuming the fabric will stretch enough.

9

Knirose Organic Baby Bassinet Sheets 2 Pack: Best for a deeper pocket

8.9/10Our score

• Organic cotton muslin
• 2 sheets
• 33 x 17 in
• 6.5 in pocket depth

The 6.5 in pocket depth is greater than the 4 in depth listed for several other options here. Compare your mattress depth and follow your bassinet maker's guidance for sheet fit.

See it on Amazon

Pros

• Two sheets
• 6.5 in pocket depth
• Machine washable

Cons

• Verify the deeper pocket works with your mattress

Knirose offers organic cotton muslin with a 6.5 in pocket depth, deeper than the 4 in depth stated for several other picks. The sheet measures 33 x 17 in, and the full elastic band is designed to cover the mattress.

The 2-pack is machine washable. Its deeper pocket may be useful only if it matches your bassinet's mattress and approved bedding setup, so check the bassinet instructions before choosing a sheet with extra depth.

The product details describe organic cotton and GOTS certification. If organic materials are central to your search, also compare our best waterproof bassinet sheets for a different type of sheet and protection.

Which cotton weave suits a bassinet mattress?

Jersey knit is stretchy, while muslin is a woven cotton fabric with a lighter feel. Choose based on the texture you prefer, then make sure the finished dimensions match your mattress.

A knit may be easier to stretch over a pad, as with the KeaBabies Soothe sheets. Muslin options offer several sheet counts and sizes, including 33 x 17 in, 33 x 20 in and 32 x 17 in.

Descriptions such as “breathable” are not a substitute for a safe fit. Use only sheets made for the bassinet mattress and follow the model's sleep and bedding instructions.

How should you wash cotton bassinet sheets?

Follow the care directions for the exact set you buy. The options here are described as machine washable, and KeaBabies also describes its sheets as dryer friendly.

Having a spare sheet can help you change bedding while another sheet is in the wash. A 2-pack may be enough for frequent laundry, while a 3-pack gives you one more clean sheet in rotation.

How do you check bassinet sheet fit?

Measure the mattress length, width and depth, then compare all three with the sheet's stated dimensions. A familiar shape or broad fit claim doesn't guarantee a snug fit on your particular mattress.

Check the bassinet maker's instructions for approved bedding. After fitting a sheet, make sure it lies flat and stays in place as directed by the manufacturer.

Which cotton bassinet sheets should you choose?

Pick KeaBabies if you want a stretchy organic cotton knit in a 33 x 17 in size, or Gllquen if you want a 3-pack of muslin. Choose by exact mattress measurements first, then compare weave, sheet count and care instructions.

Frequently asked questions

How do I choose cotton bassinet sheets?

Measure the mattress length, width, and depth, then compare those numbers with the fitted sheet dimensions. Consider whether you prefer jersey knit or muslin, and how many sheets you want available between washes.

The sheet should fit the mattress snugly and follow your bassinet maker's instructions.

Are muslin and jersey cotton the same?

No. Muslin is a light, woven cotton fabric, while jersey is a knit fabric with more stretch.

The feel and stretch can differ, so use the stated material and fit details to narrow your options.

For either weave, check the finished sheet dimensions against your mattress.

Can I use any cotton sheet on a bassinet mattress?

Use a fitted sheet made for the mattress dimensions and bassinet model. A sheet that is too large or too small may not fit securely, so don't rely on a general “universal” label alone.

Follow the bassinet maker's instructions for approved bedding.

How many bassinet sheets should I have?

Two or three sheets can give you a clean spare while another is in the wash. A 2-pack may be enough if laundry is frequent, while a 3-pack gives you another change between wash days.

Choose based on your routine and storage space.

Can cotton bassinet sheets go in the dryer?

Care instructions vary by sheet. The KeaBabies options here are described as machine washable and dryer friendly, while the other cotton picks are described as machine washable.

Check the care instructions for the specific set you choose, since washing and drying directions can differ.
