The thickness of twin-sized mattresses can vary.

Short mattress heights are cheaper, but the quality is usually lower.

Thin mattresses lack material, which can result in less comfort and support.

Everyone can find comfort and durability based on their preferences.

A wide range of mattresses is available. From low-profile mattresses for infants and toddlers to thick, deep, and tall mattresses for plus-sized and side sleepers. You can find the right thickness no matter what your sleeping position is, or what your body type is.

Poor sleep and health problems can be associated with sleeping on an uncomfortable mattress. By picking a comfort layer and base layer of appropriate thickness, you will enjoy the most comfortable and restful sleep possible.

We recommend a high-quality mattress from a reputable brand, like the Saatva Classic.

Saatva Classic is our #1 pick for 2022 (for a reason!). Provides great support and pressure relief in any sleeping position. Built to last 10-15 years with proper care. Great value.

What Is The Average Thickness Of A Mattress?

Mattresses are typically constructed with the following thickness for adequate support and comfort:

• Overall thickness between 8 and 14".
• Comfort layer at least 2-3" thick.
• Base layer at least 6-8" thick.

Mattress Thickness Chart For Twin Mattress

Mattresses available in twin sizes have the following thicknesses:

• Low profile mattresses are 2-5" thick. Designed for infants or toddlers in their cribs.
• Slim mattresses are 5-8" thick. The slim mattress is another type of low-profile mattress, but with a few extra inches for comfort.
• Standard mattresses are 8-12" thick.
• Thick, deep, or tall mattresses are 12-20" thick. Suitable for plus-sized and side sleepers, they are soft and durable.
• Extra thick, extra deep, and extra tall mattresses are at least 20" thick. It's because they're expensive, difficult to get into, and excessive that no one uses them.

Factors Determining Mattress Thickness

The depth of a mattress depends on the thickness of each of the layers inside it.

There are usually 2 layers inside mattresses, but high-quality mattresses can have 3, 4, or more layers.

The 2 main mattress layers are:

1. Comfort layer: It is the plush top layer of the mattress. Usually, 2-3" thick to provide adequate cushion and support. Made with cotton, wool, or poly-foam. Effective in isolating motion transfer.
2. Base layer: It determines the mattress's durability. The base layer takes at least 50% of the total mattress thickness.

What To Consider When Deciding On Mattress Thickness

Consider these 6 factors when choosing a mattress thickness:

• Sleeping position
• Body type
• Sleeping alone or sharing a bed with a partner
• Specific medical conditions
• Height of your bed base

Sleeping on a mattress that is too thin or too thick may lead to poor sleep and health problems. A good tip when buying a new mattress is to consider its height as this may be able to give you an idea of how comfortable the mattress will be.

It's important to choose a mattress with a great balance of cushioned firmness and contouring support from a reputable brand. The Saatva Classic is our top choice of a high-quality mattress currently.
