A twin bed is a popular option for kids’ rooms. It’s the ideal size for smaller bedrooms but still provides space for a child to spread out, relax, and sleep comfortably. Naturally, without the right mattress for their twin bed, children won’t get the restful sleep their developing bodies and brains need.

Your child may sleep better on one type of mattress over others; innerspring, foam, hybrid, latex, and pillow top varieties offer different levels of padding and support. This guide outlines each type and other shopping considerations, from contouring and pressure relief to sleeping position.

Types of Mattresses

One of the biggest decisions to make before purchasing a mattress is the type, since each is best suited to different sleepers’ needs. There are five main mattress varieties to consider for your child:

Innerspring

Innerspring mattresses feature a core designed with steel coils. The coils are covered with foam, such as memory foam or polyfoam, to provide cushioning and comfort. Innerspring is typically a firm mattress option preferred by many back and stomach sleepers.

These mattresses are springier, more responsive, and less contouring than most other mattress types. Innerspring mattresses with individually wrapped coils can limit motion transfer from one side of the bed to the other and offer more targeted pressure relief.

Foam

Foam mattresses are designed with layers of memory foam or polyfoam. Additional layers for support from a denser foam typically help make up these mattresses. A foam mattress is highly contouring and can offer relief from pressure for all individuals, especially those who sleep on their side. Foam mattresses can be effective at limiting motion transfer.

Hybrid

Hybrid mattresses combine features from different mattress types. They typically have a pocketed-coil support core along with other layers made from materials such as memory foam, polyfoam, and latex. A hybrid mattress is supportive but also offers pressure relief and body-conforming properties.

The coil design of these mattresses allows for sufficient airflow to regulate the temperature. Since hybrid mattresses often feature individually wrapped coils plus have a layer of memory foam, they can be a good option if you’re looking for a mattress to limit motion transfer.

Latex

Made from rubber tree sap and chemical fillers, latex is responsive and offers some contouring properties. Unlike memory foam that sinks in too much for some users, latex mattresses prevent individuals from sinking too deep into the mattress.

Latex is more breathable than memory foam and other foam types, so it allows for a cooler sleep space. The elasticity of a latex mattress that allows it to conform to an individual’s body also reduces the transfer of motion from one side to the other.

Pillow Top

Pillow top mattresses typically feature an innerspring base with an additional top layer of padding. This padded top layer is usually between 2 and 4 inches thick and may be made from memory foam, latex, wool, gel, fiberfill, or other plush materials.

Pillow top mattresses are popular with side sleepers since their plush top can be very conforming and take pressure off the joints. The design of the mattress beneath the pillow top layer will affect how effective this mattress type is at limiting motion transfer.

What to Consider When Choosing the Best Twin Mattress for Kids

When searching for a child’s mattress, there are many things to consider, including the child’s age, mattress quality, and whether the mattress will age well as your child grows. Also, consider the height of the adults in the family, since the size of the mattress will matter as your child grows. Ultimately, the best children’s mattress will consider some or all of the factors below and provide the rest your kids need for their growing bodies.

Size and Thickness

Twin mattresses come in three sizes: twin, twin XL, and narrow twin. Each size serves a specific purpose.

  • Twin mattresses are the most popular size. They measure 38 inches wide and 75 inches long and are ideal for younger kids. But as kids grow older, at 75 inches long, a twin mattress may not work for taller teenagers. They might find their feet dangling off the edge of the bed.
  • Twin XL mattresses provide the same amount of room in width but offer 5 extra inches in length. At 80 inches long, a twin XL mattress suits taller teenagers and adults.
  • Narrow twin mattresses measure 30 inches wide and 75 inches long. These thin mattresses are great for cots or for RVs and bunk beds, where space is limited. A narrow mattress is usually about 6 inches thick.

Standard mattresses are between 8 and 12 inches thick. The following thicknesses work best for different sleeping positions:

  • Back sleepers: 10 to 12 inches
  • Stomach sleepers: 10 inches
  • Side sleepers: 12 to 14 inches
  • Combination sleepers: 12 inches

Firmness Level

Manufacturers typically indicate how firm a mattress is using a scale from 1 to 10, with 1 being a very soft mattress and 10 being a very firm mattress. Mattresses on the softer end of the range (with a firmness between 1 and 3) are plusher and allow the body to sink relatively deep into the mattress for a more cradled feeling.

On the firm end of the scale (between 7 and 10), mattresses are quite the opposite; they offer more support and less contouring around the body. Firm mattresses provide the most spinal alignment, though they might feel uncomfortable for some sleepers.

Mattresses with a medium firmness (between 4 and 6) are a middle ground between plush and firm; these offer more support than soft mattresses while feeling less solid than mattresses on the higher end of the scale.

Age and Sleeping Position

The four most common sleeping positions for kids are back, stomach, fetal position, and side. Kids will sleep equally on their side, back, and stomach, but as they grow older, most will eventually gravitate to side sleeping—probably with one arm overhead, since this is the most common sleeping position. The best sleeping position for babies and toddlers and children from birth to age 5, is lying on the back.

Your child’s sleeping position will help determine the type of mattress best suited for them. For example, side sleepers will feel comfier when their hips and shoulders sink into the bed, so they may prefer a soft mattress. On the other hand, back sleepers will want support in their midsections and might choose a firmer mattress. Kids who move around a lot at night might sleep best on a combination mattress.

Temperature Regulation

Cooling mattresses often feature breathable materials that allow for more air circulation and prevent the mattress from retaining heat. If your child is a hot sleeper, consider a mattress with coils that promote airflow, or look for foam infused with cooling gel or activated charcoal. Gel absorbs heat and keeps the mattress’s temperature from getting too warm, while charcoal is a naturally cool substance.

Cooling materials may also be integrated into the cover of a mattress to make it more breathable. For instance, Tencel is a very breathable fabric that can wick away moisture. Some cooling mattresses have phase change material (PCM) integrated into the cover, which absorbs body heat. These fabrics can then release the heat back if the body cools down too much.

Edge Support

The edge support on a mattress can affect how easy or challenging it is for your child to get in and out of bed. Mattresses with weaker edge support are softer around the edges and may sink down when individuals sit on the edge of the bed. A mattress with firmer edge support, on the other hand, won’t sink down as much, which simplifies the task of getting in or out of bed.

Edge support can also affect the usable sleeping space on the top of the mattress. It is possible to sleep right up to the edge of a mattress with firm edge support, but it’s not as easy to do so on a mattress with weaker edge support.
