Mattress Topper Sizing Tips
- Measure First: Measure your mattress length and width at the widest points to ensure proper fit
- Corner Straps: All toppers include 4 elastic corner straps that fit mattresses up to 18-20 inches thick
- Between Sizes: If your mattress falls between sizes, choose the bigger size to ensure coverage. Topper can easily bend over excess sides.
- Split King Note: For split king adjustable beds, order two Twin XL toppers instead of one King topper
Pillow Sizes
| Size | Dimensions | Wool Pearl Fill Weight | Best For |
|---|---|---|---|
| Queen | 20" × 30" | 2.5 lbs | Most sleepers, fits standard pillowcases |
| King | 20" × 36" | 3.5 lbs | Those who prefer larger pillows, king beds |
Special Considerations
For College Students
Most dorm beds require Twin XL (80" × 39") toppers. This size is longer than a standard Twin to accommodate taller students and is the most common dorm mattress size.
For Adjustable Beds
Our toppers work well with adjustable beds, with one exception: King size toppers do not work with split adjustable king beds. For split kings, purchase two Twin XL toppers.
For Couples with Different Preferences
Couples with different comfort preferences on a king bed can use one Twin XL toppers. Note that only two corner straps will be functional with this arrangement.
How to Measure Your Mattress
- Remove all bedding from your mattress
- Measure the length from head to foot at the longest point
- Measure the width from side to side at the widest point
- Compare your measurements to our size chart
- If unsure, measure twice to ensure accuracy
Sizing FAQs
Q: Will the 2-inch topper make my bed too high?
A: Most fitted sheets will still fit comfortably with the added 2 inches. Deep pocket sheets work perfectly, and the added height is generally not noticeable for getting in and out of bed.
Q: Do you offer custom sizes?
A: We specialize in standard U.S. sizes only. Custom sizing is not available due to our handmade production process.
Q: Can I use the topper on a European-sized bed?
A: Our toppers are designed for U.S. standard sizes. European bed dimensions differ, so please measure carefully and compare to our size chart.
