On Walmart.com, extra deep pocket sheets commonly fit mattresses about 18–24 inches deep. You’ll see listings that note a specific pocket (like 22") or a range (such as “fits 18–24"). Pocket depth can vary by size and style, so it’s helpful to check the product’s “pocket depth” or “fits up to” details.

• Measure your bed: Include any toppers or pads to get the true depth.
• Choose the right fit: A sheet that’s equal to or slightly deeper than your measurement can help reduce slip.
• Check features: All-around elastic or corner straps can improve hold on taller mattresses.

Availability may vary by size and color, so reviewing the item description before you buy is a good idea.

The difference is mainly the fitted sheet’s pocket depth (how tall a mattress it can cover).

• Deep pocket: Typically fits mattresses around 14–18 inches thick.
• Extra deep pocket: Generally fits about 18–24 inches, which helps with pillow-top beds or mattresses with toppers.

These ranges are common guidelines, but labels can vary by style. Always check the product details for “pocket depth” or “fits up to” to match your mattress. Keep in mind, pocket depth refers to the fitted sheet only—flat sheets and pillowcases follow standard sizing for the bed size you choose. If you’re between depths, all-around elastic or anchor features can offer a more secure fit.

1. Strip the bed: Remove sheets and mattress protectors so you’re measuring the bare mattress (or include a topper if you use one).
2. Measure bottom to top: Use a tape measure from the mattress base to the highest point at a corner.
3. Include toppers/pads: If you sleep with a topper, add its thickness to your total.
4. Round up: Note the depth in inches and round up to the next inch.
5. Match the listing: Choose a fitted sheet with a pocket depth equal to or slightly greater than your measurement.

For example, a 20" mattress with a 2" topper calls for around a 22" pocket. Check the item’s “pocket depth” or “fits up to” to confirm compatibility.

A snug, secure fit starts with matching your sheet’s pocket depth to your mattress height. A sheet that’s too shallow can pop off, while one that’s much deeper can bunch.

• Match the depth: Choose a pocket that meets or slightly exceeds your measured mattress depth.
• Look for hold features: All-around elastic, reinforced corners, corner straps, or anchor bands can help reduce shifting.
• Install carefully: Pull the fitted sheet firmly under all four corners; tuck excess fabric underneath.
• Care for elasticity: Follow the care label; gentle cycles and low heat can help maintain stretch.

If you use multiple toppers, consider a pocket depth that accommodates the total stack to improve stability.

Yes, you can find extra deep fitted sheet–only options as well as full sheet sets on Walmart.com. Availability depends on size and color, but you’ll often see single pieces and multipacks.

• Confirm what’s included: Check the listing to ensure it’s a fitted sheet only, not a set.
• Verify pocket depth: Look for “22" pocket” or “fits 18–24"” to match your mattress.
• Choose your size: Options may include Twin XL, Full, Queen, King, and California King.
• Pick a fabric: Microfiber for easy care, cotton or blends for breathability, jersey or fleece for extra coziness.
