The mattress sheet that goes on top of a mattress has several common names that people use interchangeably. The most accurate term for this bedding layer is “mattress pad” or “mattress topper”, but other names like “mattress cover” or “mattress protector” are also used. To understand the differences between these terms, we’ll look at the purpose and construction of mattress pads versus other bedding layers.
A mattress pad, also known as a mattress topper, is a removable layer that goes on top of the mattress to provide extra comfort and cushioning. Mattress pads are typically made from materials like memory foam, down or down alternative fibers, wool, cotton, latex foam, or polyester. The goal of a mattress pad is to contour to your body shape and relieve pressure points, so you can sleep more comfortably. Many mattress pads are between 1-4 inches thick. Thicker mattress pads offer more plush padding. Since mattress pads are designed to improve the feel of the mattress, they are considered a bedding accessory rather than a necessity.
Mattress Cover
A mattress cover is a thin, quilted layer that encases the entire mattress. Its main function is to protect the mattress from spills, stains and normal wear and tear. Mattress covers zip around the mattress like a fitted sheet. They are made from cotton, polyester, or blend materials that feel soft to the touch. Underneath the quilted top layer, most mattress covers have a waterproof barrier to resist liquids and allergens. Regular mattresses covers can be removed and washed occasionally. Unlike a mattress pad, a mattress cover does not add extra cushioning or significantly change the firmness of the mattress. It simply safeguards the mattress itself.
Mattress Protector
The terms “mattress protector” and “mattress cover” are sometimes used interchangeably. But technically, a mattress protector serves a slightly different function than a standard mattress cover. Mattress protectors provide an extra moisture barrier against accidents, spills and stains. They are designed to protect the inner mattress layers from liquids and allergens. Most mattress protectors have a waterproof vinyl or polyurethane layer bonded to the fabric. This blocks moisture and other contaminants from seeping into the mattress. Mattress protectors can be purchased separately to use in conjunction with a mattress cover. They provide an added safeguard for mattresses, especially for children or incontinent adults.
Fitted Sheet
A fitted sheet is stretchy bedding that fits snugly around the mattress. It is not to be confused with a mattress cover. Fitted sheets go over the top of the mattress to cover it and provide a soft surface for sleeping. But fitted sheets do not offer any cushioning or mattress protection. Their stretchy corner pockets allow them to hug the mattress so they do not shift around. Fitted sheets touch the skin directly. They protect sleepers from friction against the mattress cover. Fitted sheets require occasional washing to keep them fresh. They come in standard mattress depths, so it’s important to find the right fitted sheet size for your particular mattress.
Mattress Pad Construction
The materials used in a mattress pad affect its comfort, support, and breathability. Here are some key mattress pad constructions:
Memory Foam: Memory foam contours to the shape of your body and relieves pressure points. Gel-infused memory foam helps regulate temperature.
Down and Down Alternative: Luxurious down and down alternative fibers offer plush comfort. However, they don’t provide much support.
Polyester Fiber: Lightweight and budget-friendly option. Polyester fills offer some cushioning but not advanced pressure relief.
Wool: Natural wool wicks away moisture and regulates temperature. Provides cushioning comfort.
Latex Foam: Natural latex contours to the body like memory foam. It’s responsive, breathable and antimicrobial.
Cotton: Soft, breathable cotton mattress pads add surface-level comfort. Not much support.
| Material | Key Features |
|---|---|
| Memory Foam | Superior pressure relief, contouring |
| Down | Luxurious softness, loft |
| Polyester | Lightweight, budget-friendly |
| Wool | Moisture-wicking, temperature regulating |
| Latex Foam | Responsive support, breathability |
| Cotton | Soft, cool surface |
Choosing a Mattress Pad Thickness
Mattress pad thickness ranges from 1-4 inches. Thinner 1 inch mattress pads add a light layer of padding. 2-3 inch pads offer plush comfort and deep contouring. Here is how mattress pad thickness affects feel:
| Thickness | Benefits |
|---|---|
| 1 inch | – Light, breathable comfort |
| 2 inches | – Balanced comfort and support |
| 3 inches | – Plush cushioning and pressure relief |
| 4 inches | – Maximum contouring and luxury feel |
When selecting a mattress pad depth, think about your sleep position and firmness preferences. Side sleepers and those who like a soft mattress generally prefer a thicker 3-4 inch mattress topper for ample cushioning around their shoulders and hips. Back and stomach sleepers who need more support may opt for a 1-2 inch mattress pad.
Mattress Pad vs. Mattress Protector
To recap the key differences:
Mattress Pad:
– Made of cushioning materials like memory foam or down
– Alters mattress feel and provides contouring
– Removable layer placed on top of the mattress
– Available in various depths up to 4 inches
– Adds comfort and relieves pressure points
Mattress Protector:
– Made of thin, breathable fabrics like cotton or polyester
– Does not affect mattress firmness or feel
– Encases the entire mattress like a fitted sheet
– Waterproof layer blocks spills and stains
– Safeguards mattress without adding padding
Mattress Pad vs. Mattress Topper
Mattress pad and mattress topper are essentially interchangeable terms. They both refer to removable, cushioning layers that go on top of the mattress. The terms can be used for bedding accessories of any material construction.
There are a few theories about how the terms originated:
– “Topper” may come from the concept of “topping” or garnishing the mattress for added comfort.
– “Pad” may refer to padding or cushioning.
– Mattress companies may use one term over the other for branding reasons.
But in general, mattress pad and mattress topper can be used synonymously for the same type of bedding product.
Mattress Pad Benefits
Reasons to use a mattress pad include:
– Makes a firm mattress feel softer and more cushioned
– Alleviates pressure points for side sleepers and people with aches/pains
– Protects mattress from sweat, oils and microbes
– Extends the mattress lifespan by absorbing body impressions
– Adds plush comfort and conforms to body shape
– Affordable way to adjust mattress feel
– Helps regulate temperature with cooling gels or wool
– Natural materials like wool or latex are hypoallergenic
– Easy to remove and clean in the washing machine
Buying Guide for Mattress Pads
Follow this checklist when shopping for a mattress pad:
– Choose the right size for your mattress
– Select a depth between 1-4 inches based on preferences
– Consider materials like memory foam, down, wool, cotton
– Assess if you need cooling properties to sleep cooler
– Look for hypoallergenic materials if you have allergies
– Carefully review policies on returns, warranties, trial periods
– Check that the mattress pad fits securely over your mattress
– Wash the mattress pad before first use for best results
Conclusion
While mattress cover, mattress protector, topper and pad all refer to different bed layers, “mattress pad” most accurately describes a cushioning accessory that sits atop the mattress. Mattress pads provide plush comfort without altering the support system of the mattress itself. Choose a mattress pad if you want to soften a firm mattress or alleviate pressure points without buying a new mattress. Mattress pads come in different materials, depths and features to suit your sleep preferences.
