Types of Sheets
Don’t know the difference between a fitted sheet and a flat one? Here’s a quick guide on the types of sheets you’ll encounter when shopping for bedding.
Fitted Sheets
A fitted sheet is designed to fit perfectly onto your mattress. It typically has elastic in the corners to help the sheet grip onto the mattress. Fitted sheets need to be specifically sized to complement the mattress dimensions. If the fitted sheet is too big, the sheet will fall off. You’ll have trouble getting the elastic over the mattress corners if it's too small. Opt for deep-pocketed sheets for thicker mattresses.
Flat Bed Sheets
As the name suggests, flat bed sheets are meant to lie flat on the mattress on top of the fitted sheet. They should be larger than the mattress surface. The extra fabric that hangs over the sides is then tucked under the mattress.
Duvet vs. Comforter
A duvet is a thick blanket filled with down, feathers, wool, silk, or synthetic material. Duvets require a duvet cover sheet that you can take off to clean. A comforter is a thicker blanket that covers your sheets & provides warmth. This bedding lies on top of the bed and drapes slightly over the edge of the mattress. Viscosoft’s down reversible comforter can be used as a duvet insert and a comforter. With sewn corner loops and eight ties, you can easily add our duvet cover that fits inside standard-size duvet covers. Be sure to find a cover with ties!
Mattress Topper
Lastly, a mattress topper is placed directly on top of an existing mattress. Still, the primary function of a mattress topper is to immediately revitalize your sleep surface by improving support, reducing pain, and creating a cooler, cleaner, more enjoyable sleep environment.
How To Measure a Flat Sheet?
Remove sheets from your bed and measure the width and length of your mattress. Then measure the height of your mattress, including mattress toppers. Write these dimensions down. Your fitted sheet should match or be slightly larger than these dimensions.
Next, measure your fitted sheet. Lay the sheet out to find which side is the length (the longer side). Measure from one corner to the other to find the length measurement. Then measure the shorter side, from corner to corner. This is the width. Lastly, take your fitted sheet and measure along the pocket seam. This will tell you the height.
The fitted sheet should fit if these measurements are equal to or slightly larger than your mattress measurement. If they are much larger, the sheet might bunch up in the night and come off. If they are smaller, the sheet will not fit.
Mattress Depth
Many people want extra support or cushion on their mattresses. Mattress toppers will add to the depth or height of the bed. Be sure to consider your full mattress depth when purchasing fitted sheets. A standard fitted sheet typically has a depth of 12 inches. Deep pocket fitted sheets can provide a depth of up to 18 inches.
Washing Your Sheets
When you get sheets, the first thing you should do is wash them. Sheets may have been in contact with chemicals in production and transportation, so cleaning them is important. However, it’s essential that you follow the washing instructions on the label. If your sheets shrink, they probably won’t fit your mattress anymore.
Now that you know everything about bed sheet sizes, you can purchase bedding confidently and know it will fit perfectly onto your mattress. You’ll be snug in your new sheets in no time. Top off your dreamy oasis with a calming faux fur blanket that’s designed for the ultimate relaxation
