Safety first
- Not for babies. A twin mattress is not a safe sleep surface for a baby under 1. Babies should sleep on their backs on a firm, flat crib, bassinet or play yard mattress.[1]
- Bunk beds: children under 6 should not sleep on the upper bunk. Use the mattress size and maximum thickness the bunk bed maker lists, so the guardrails stay at least 5 inches above the top of the mattress.[2][3]
- Fit: a twin mattress is about 38 x 75 inches. It should fill the bed frame with no gap a child could slip into.
The Importance of the Right Mattress for Your Kids
Good sleep matters for everyone, and especially for growing children. Choosing the right mattress for your child is mostly about comfort and a supportive surface that stays flat and doesn’t sag, so they can sleep well. There is no medical evidence that one mattress type or firmness sets up a child’s lifelong posture or prevents back problems in adulthood. Pick a mattress your child finds comfortable. Sleeping well helps children feel refreshed when they wake up the next day. Some children have allergies or sensitive skin. Look at what the mattress and cover are made from and which certifications the maker states, and ask your pediatrician if your child has allergies or eczema. A good mattress is one part of healthy sleep habits that keep your child happy and rested.Kid Mattress Shopping Buying Considerations
Here are a few important things to consider before buying a mattress for your child.- Your Kid’s Age, Size, and Bed – get a mattress that fits the bed frame with no gaps. A twin mattress is about 38 x 75 inches. Thicker mattresses suit standard bed frames, while thinner ones (often 5 to 6 inches) are common on bunk and trundle beds. Bunk bed instructions must state the maximum mattress thickness, so check it before you buy.[2]
- Allergies or Sensitivities – if your child is very sensitive or has allergies, you may prefer natural fabrics and certified materials (see the labels below). No label means a mattress is allergy-proof.
- Removable Cover – handy for accidents. Some mattresses have a fire barrier made with fiberglass under the cover; never remove a cover the label says to keep on. If you want to wash the cover, choose one the maker lists as removable and fiberglass-free.
- Flammability – every mattress sold in the US must meet the federal open-flame standard, 16 CFR 1633.[4]
Features of a Good Twin Mattress for Kids
Here are some mattress features to be aware of before buying a mattress for your child:- Memory Foam – this foam softens with body heat and contours to your body shape when you lie on it. Many people find it comfortable. Memory foam can also be infused with charcoal or gel, which makers say adds freshness or cooling.
- Multiple Layers – mattresses often have several layers, each adding comfort or support. More layers doesn’t automatically mean better.
- Individually Wrapped Springs – if you buy a spring mattress, individually wrapped (pocketed) coils are usually quieter and move less than an open coil.
- Ventilation – foam mattresses can feel warm. Open-cell foam, perforations or ventilation channels help heat escape.
- Pressure Relief – a mattress that spreads out pressure feels more comfortable to sleep on, especially for side sleepers.
What the Labels Mean
- CertiPUR-US: the foam is made without formaldehyde, ozone depleters, CPSC-regulated phthalates, mercury, lead and other heavy metals, and has low VOC emissions.[5] It covers the foam, not the whole mattress.[5]
- OEKO-TEX STANDARD 100: the textile was tested for a list of harmful substances.[6]
- GREENGUARD Gold: the product meets strict limits for chemical emissions into indoor air.[7]
