Single Mattress:
A single mattress is designed for one person and is ideal for children, teenagers, or adults who need a compact sleeping space. Its smaller size fits comfortably in most bedrooms, making it perfect for kids’ rooms, guest rooms, or smaller apartments. Single mattresses are versatile and work well with a variety of bed frames such as standard divans, platform beds, or loft beds, providing a practical and space-saving sleep solution.
Small Double Mattress:
Small Double mattress protectors are designed specifically for small double mattresses. Small double mattresses are ideal for teenagers, single adults who want extra space, or smaller guest rooms where a standard double might be too large. Their compact size makes them a great choice for apartments or rooms with limited space. Small doubles also work well with a variety of bed frames, including divans, platform beds, and storage beds, offering flexibility without sacrificing comfort.
Double Mattress:
A double mattress is designed to comfortably sleep one or two people, making it a popular choice for couples or individuals who want extra space. It’s wider than a single mattress but still fits well in most bedrooms, offering a good balance between comfort and space efficiency. Double mattresses work with a variety of bed frames, including divans, platform beds, and storage beds, making them a versatile option for many home layouts.
King Mattress:
A king mattress provides ample space for couples or individuals who prefer a larger sleeping area for maximum comfort. It is wider and longer than a double mattress, making it perfect for master bedrooms or larger rooms where space is not a constraint. King mattresses pair well with a variety of bed frames such as divans, platform beds, and adjustable bases, offering a luxurious and spacious sleep experience.
Super King Mattress
A super king mattress offers the ultimate in sleeping space and comfort, ideal for couples who want plenty of room to stretch out or for families who co-sleep with children. It is larger than a king mattress, making it best suited for spacious master bedrooms. Super king mattresses work well with robust bed frames like divans, platform beds, and adjustable bases, providing a luxurious, roomy sleep environment for a truly restful night.
What is the Depth of a Mattress Protector?
The depth of a mattress protector should be at least 1 inch thicker than your mattress for a snug fit. This ensures the protector covers the entire mattress, including the sides, and stays secure throughout the night.
Typical mattress protector depth ranges:
Standard depth: About 6 to 9 inches (15 to 23 cm): fits most regular mattresses
Deep pocket: Around 12 to 15 inches (30 to 38 cm): for thicker mattresses or those with pillow tops
Extra deep pocket: Up to 18 to 22 inches (46 to 56 cm): for very thick mattresses or mattresses with toppers
How do I know what size mattress protector I need?
You need a mattress protector that matches the exact size of your mattress, including its length, width, and thickness (depth).
Steps to Measure Your Mattress Protector Size
To know what size mattress protector you need, first measure your mattress dimensions carefully:
Measure the length and width: Use a tape measure to find the mattress length and width from edge to edge. This will tell you which standard mattress size you have (e.g., Double, Single, King).
Measure the depth (thickness): Measure the thickness of your mattress from top to bottom, including any pillow tops or mattress toppers you use. Mattress protectors come with varying pocket depths, so it’s important that your protector can fully cover your mattress sides.
Match to mattress protector sizes: Mattress protectors are sized to fit standard mattress dimensions. Choose one that matches both your mattress size (length and width) and depth to ensure a snug, secure fit without bunching or slipping.
