Crown Posture Bedding EssentialSupport Mattress, Medium
Long Single · 7 sizes available
Mattresses sized for growing kids, from single through to double, with comfortable and supportive options you can try out in-store or shop straight online.
Kids spend more of their lives asleep than adults do, and they are growing while they do it. A kids mattress needs to support a developing spine, shrug off the occasional accident and keep pace with growth spurts. This range brings together single, long single and king single mattresses under $1,000 from Sealy, Sealy Posturepedic, Crown Posture Bedding, Active Sleep and MLILY, in plush, medium and firm feels.
Support comes first. Children are light, so they do not need a hard mattress to get it, but they do need a surface that keeps them comfortably supported whether they sleep on their back, side or front. Many parents choose a medium or firm feel for that reason. Breathability matters too, because children run warm at night, and so does easy care: a good mattress protector saves a lot of washing. Look for a mattress with a solid warranty, since a kids mattress often outlasts the first bed it was bought for.
Most children move into a single mattress (92cm x 188cm) after the cot, and it will see them through primary school. A long single (92cm x 203cm) adds leg room for a tall child in a narrow room, and a king single (107cm x 203cm) is the size that takes a child through to the end of their teens without a second purchase. For a bunk or trundle, check the maximum mattress depth first; this range includes slim, low-profile designs made specifically for those beds. Our bed size guide lays out every dimension.
Bonnell and pocket spring mattresses give a child the familiar, supportive feel of a grown-up bed with plenty of airflow through the springs, and they make up most of this range. Foam mattresses are lighter to move, quieter when a child wriggles, and easier to fit into a bunk or trundle, and the all-foam kids option here comes with a kid-friendly cover. Either works well; let the bed, the room and your child's sleeping style decide. A trusted Sleep Advisor can help you compare both in-store.
Pair the mattress with one of our kids beds, from simple singles to trundle and storage styles, all under $1,000. Add a waterproof mattress protector from the first night, a low pillow suited to a child's neck, and a quilt matched to the season. Selected ranges are covered by the Forty Winks 90 Night Comfort Guarantee, and our product care guide explains how to keep the mattress fresh for years.
Many parents choose a medium or firm feel. Kids are light, so they do not sink far into a mattress, and a supportive surface suits a growing body. Very plush, deep-cushioned mattresses are usually chosen for adults rather than children. If you are unsure, a trusted Sleep Advisor can show you the options in-store.
A single (92cm x 188cm) suits most children moving out of a cot. A long single (92cm x 203cm) suits a tall child in a narrow room, and a king single (107cm x 203cm) gives teenagers room to grow without needing a double. Always match the mattress to the bed frame or base you have, and check the maximum depth for bunks and trundles. See our bed size guide.
Yes. This range includes slim, low-profile mattresses designed for bunks and trundles, where a standard-depth mattress would sit too high against the safety rail or not fit under the main bed. Check the bed's maximum mattress depth before you buy and pick a mattress that stays under it.
Use a waterproof mattress protector from the first night. It keeps spills and accidents out of the mattress, washes easily and keeps the warranty intact. Rotate the mattress every few months so it wears evenly, and vacuum it when you change the sheets. Our product care guide has the full routine.
