About QVC Sheets

Thread Count
Thread count refers to the number of threads per square inch of fabric. Thread count alone does not ultimately determine softness, but it does predict the weight and airflow of the fabric. All QVC sheet sets offer a minimum thread count of 300, with select sets measuring in with a thread count as high as 1,000.

Fast Facts
A sheet with a high thread count may not yield a softer sheet. Softness comes from a combination of factors including the weave, type of cotton, treatments (such as an anti-wrinkle coating), and thread count. Depending on the manufacturing processes, sheets that contain a thread count of 300-400 can be as soft or softer than one with a thread count of 1,000.

Traditional Blend
The traditional blend utilizes cotton's natural ability to allow fabrics to breathe and wick away moisture. This blend mixes long and short fibers when twisting them into threads.

Egyptian Cotton
Widely considered to be one of the highest qualities of cotton available, Egyptian cotton is grown in Egypt and consists of fibers which are longer, resulting in a silkier thread.

Supima® Cotton
This is the name used to promote textile and apparel products made with 100% American Pima cotton, grown in the southwestern United States. The staple length of Supima is 35% longer than regular cottons. This increases softness and luster. And since fewer fiber ends are exposed, it minimizes the effects of abrasion, resulting in less pilling. The Supima trademark is a registered trademark of Supima Association of America.

The type of weave and construction used for sheets can vary from ornamental to something functional. Variations in weave and fiber used in sheet construction will affect the characteristics of the cloth. Some fibers and constructions will breathe more and other combinations can keep you warm and cozy.

Consists of a twill weave with threads layered over one another, exposing a longer thread on the fabric surface. Imparts a smooth, silky feel against the skin.

Made with a balanced and closely woven plain weave. The percale construction is both durable and smooth to the touch. Sheets made with 100% cotton percale feel smooth and crisp to the skin.

Pique sheets are designed to achieve a textured appearance with a soft touch. Its high and low texture is created during the knitting or weaving processes. Pique construction is made by spinning two yarns together to create a stronger yarn that's soft and supple.

Wrinkle Defense® Technology
The Wrinkle Defense process is designed to decrease the appearance of wrinkles for up to 50 wash cycles. It provides a durable, soft, and smooth sheet surface when the care instructions (included) are properly followed.

Flannel is a material that's woven and put through a brushing process that lifts the threads to create air pockets that impart a soft and fuzzy feel. When comparing flannel sheets, look for weight rather than thread count. A quality flannel material is in the 5-6 oz range.

Jersey Knit
Threads in a jersey knit material are knit around one another rather than woven. This construction gives the fabric some stretch (or "give") for a soft and comfortable feel. It feels like sleeping in your favorite T-shirt!

Polyester is often used in this sturdy and durable material with manmade threads. It's also easy to care for, has fewer wrinkles than comparable sheets, and looks great with prints and bright colors. Sheet sets with a higher weight are often brushed for a soft, suede-like feel.

This fabric is soft, comfortable, warm, dries quickly, and is durable for long-lasting good looks.

Jacquard refers to both a type of loom weave and the cloth produced by such looms. The jacquard process allows for intricate designs and textures to be woven into the material itself.

One of the oldest manufactured fibers dating back to the 1880s in France, rayon was originally developed as an alternate to silk and has a naturally smooth and soft texture. The material has strong moisture-wicking properties to help keep you cool and comfortable.

Frequently Asked Questions

I'm moving, what's the best way to transport my bed?

We suggest that you completely disassemble the mattress, foundation, and frame when moving the bed. Here are some tips when packing the Sleep Number® bed:

  • The cover and foam should all be double-bagged to help prevent stains.
  • The chambers should be deflated and boxed to help prevent possible abrasions and other damage.
  • The pump should be packed in a box, surrounded by some sort of packing material if the original pump box is not available.
  • The remote (if applicable), caps, and instructions should be tucked in the box with the pump to help prevent them from being lost.
  • Although the foundation is very strong and durable, it can be bent or twisted during moving which will cause damage. We recommend completely disassembling the foundation for moving.
  • Disassemble the frame and headboard, save all hardware in a bag, and tape it to one of the larger frame parts.
  • If you purchased Foundation Legs, they should be placed in a bag with all of the hardware.

If you need instructions for re-assembly of the bed, contact the Select Comfort Customer Service department via e-mail at customerservice@selectcomfort.com or toll free at 1-800-790-9298.

Will my Sleep Number® bed fit my current bedroom furniture?

Yes. Assuming you purchase the same size bed you are currently sleeping on, a Sleep Number® bed will fit in all standard-size bedroom furniture (California king, king, queen, full, or twin).

Will my Sleep Number® bed fit my current sheets?

Most of the sheets sold today are what is commonly referred to as "deep pocket" sheets. Deep pocket sheets are designed for high profile mattresses and can be found at most major department stores. If you own older sheets, which may not have been made in the "deep pocket" style, you may wish to purchase sheet clips to hold your sheets in place.

Will my bed deflate if there is a power surge or power loss during the night?

No. Your mattress will maintain its firmness, even if power is interrupted. But to help protect your Firmness Control™ System from power surges resulting from thunderstorms or power outages, we recommend using a surge protector.

Can I clean the mattress cover or foundation coverlet?

We recommend spot cleaning with sparkling water or mild detergent. Do not dry clean the mattress cover or the foundation coverlet. And by all means, do not put it into a washing machine or dryer. Also, do not stain-guard the mattress, as it may cause yellowing of the fabric.

Find Your Number

What's a Sleep Number® setting?
Your Sleep Number setting is a number between 0–100 that represents the ideal combination of mattress comfort, firmness, and support for your body, giving you the best night's sleep possible.

How to find your individual Sleep Number setting:
Step 1: Lie down in your favorite sleeping position and adjust your pillow to your liking. Using your remote, change your Sleep Number setting to 100 (firmest), and then down to 20 (very soft).

Step 2: Set your Sleep Number back to 100. As the mattress gets firmer, keep track of how your neck, shoulders, hips, and back feel. When you feel comfortably supported, stop. Make adjustments up or down by 5–10 setting degrees.

Step 3: Try sleeping at this setting for 3–5 nights. If you need to make an adjustment, change your number by 5–10, and try this new setting for 3–5 nights.

How to evaluate your comfort level:
As you customize the Sleep Number bed for your optimum comfort level, you'll want to evaluate your sleep position and determine how you feel as compared to the diagrams provided here, then make adjustments to your firmness or pillow if needed. Your pillow should help keep your body aligned properly, otherwise it may interfere with your ability to sleep comfortably.

Give it time:
It sometimes takes several nights of sleeping at different settings to discover your ideal Sleep Number setting. If you would like to experiment further with your Sleep Number, you may want to consider keeping a sleep journal.

When you have found a Sleep Number setting where you feel comfortable, log this number into your sleep journal. Try to sleep at this Sleep Number setting for 3–5 nights, adjusting in increments of 5 or 10. It'll take your body that long to become accustomed to a new sleep surface.

After five nights, reevaluate your comfort level and log the new setting into your sleep journal, adding comments if helpful. Repeat the process until you have found the perfect setting for you.
