To keep your fitted sheet on your bed, choose the right size for your mattress and use tools like sheet clips, suspenders, or velcro strips for extra security. High-quality sheets with deep pockets also help ensure a snug fit.


In recent years, social media has become enamored with a new trend: #oddlysatisfying.1 From cucumbers sliced into perfectly equal pieces to pressure washers erasing grime from smudged-up sidewalks, our brains delight when things line up right.

Another #oddlysatisfying candidate? A set of fitted sheets that hug your mattress perfectly. That’s not even odd — just an unbeatable feeling.

But maybe you’ve invested in some fitted sheets that seem dead set on popping off. Or maybe, despite your best efforts, every morning is a lumpy mess. That’s the opposite of satisfying. 

To keep fitted sheets on your bed, choose high quality bed sheets that are the right size for your mattress. You can also employ specialized tools like sheet clips or velcro strips. 

If you’re wondering how to keep fitted sheets on bed corners, read on to discover the top 6 ways to achieve a tailor-made fit.      

#1 Choose the Right Size

A fitted sheet comes equipped with elastic corners that tightly squeeze your mattress. By keeping your bed in a perpetual bear hug, a fitted sheet acts as a protective shield and provides a smooth, cozy base layer for your flat sheet. Learn more about the fitted vs flat sheet in our blog.

To achieve a satisfyingly snug fit, you’ll first need to determine your mattress size. If you don’t know how big your mattress is, you can either use a measuring tape to determine its length and width, or remove the current sheets and search for a sizing tag. 

Mattresses come in the following bed dimensions:

  • Twin (38” wide, 75” long)
  • Twin XL (38” wide, 80” long)
  • Full (53” wide, 75” long)
  • Queen (60” wide, 80” long)
  • King (76” wide, 80” long)
  • California King (72” wide, 84” long)

Once you’ve zeroed in on the size, you’ll also want to verify your mattress thickness. Fitted sheets come with elastic pockets that need to cover the mattress corners completely — they can’t do this if the mattress is too deep. 

Mattresses come in five degrees of thickness:

  • Low profile (2-5” tall)
  • Slim profile (2-8” tall)
  • Standard profile (8-12” tall)
  • Thick profile (12-20” tall)
  • Extra thick profile (20” or greater)

Learn more about which thickness is right for you in our mattress thickness guide.

Additionally, if you use a comfy mattress topper or a mattress pad, this will increase the thickness, so make sure to account for it when selecting your sheet set.

To guarantee a perfect match, choose sheets that match both the dimensions and depth of your mattress. If you have a thicker mattress or an adjustable bed, consider options with extra deep pockets to prevent sheet slippage.

#2 Use Sheet Clips or Straps

For a little extra security, you can fasten your sheet’s corners down with specially designed sheet clips. Or, if you’re the rugged DIY type, you can hunt down a set of four elastic straps and sew them onto the corners to hold your sheet in place.

Elastic straps can help keep the sheet taut by eliminating excess fabric that might cause the fitted sheet to pop off during the night. These straps are especially useful if you have a mattress topper or a mattress pad that adds extra height to your mattress.

#3 Try Sheet Suspenders

You can also keep your sheets taut (and give them a dash of fashion flair) by using sheet suspenders, which do as fine a job on bedding as they do on hipster slacks.

Simply attach the suspenders to all four corners of your sheet and cross them underneath the mattress (in the shape of an “X”). Most sheet suspenders are adjustable, so they can save you time on measurements and help you avoid the frustration of a slipping sheet.

#4 Employ Non-Slip Rug Grippers

Another unsatisfying feeling? When a rug slides around under your feet. To combat this, you can place non-slip rug grippers at the corners of your carpet to help it stick to the floor.

You can take the same approach to your sheets. Pick up a set of rug grippers and place them under the mattress where the bottoms of your fitted sheet pockets would go. Add the bedding and press the corners of your fitted sheet against the grippers — now they’re not going anywhere.

#5 Use Velcro Strips

Velcro burst onto the scene in 1955,2 and it’s been holding things together ever since. Fix wonky sheets by picking up some velcro strips and sewing the rough side onto your mattress corners, and the soft side into your sheets. 

Line up your sheet with the correct mattress corners and choose one corner to designate as your “guide.” Clip a small piece out of this velcro piece (or mark it another way) so you can easily orient your sheet when putting it on.3

#6 Opt for High-Quality Sheets

While there’s always a workaround, well-crafted sheets do a better job of staying tight.

Opting for top-shelf choices like The Casper Hyperlite Sheet Set is a fantastic way to ensure your sheets fit like a glove. 

Plus they’re made of 100% Tencel, which means: 

  • Airy softness
  • Cool slumber
  • Exceptional breathability

But Tencel isn’t just feathery bliss: it’s also highly durable — no wrinkles or tearing even after years of a perfect, tight fit.4 Learn more about Tencel vs cotton sheets in our blog.
