Many people treat their kid’s mattress as disposable. As the thinking goes, the kids will wear it out, pee it out, jump it out…
Mattresses come in different sizes and of course different comfort and cost levels. Generally kids get the short end of the stick – the smallest size (which makes sense) and about the cheapest parents can find.
If mattresses aren’t protected by a water proof cover then keeping a kids mattress clean is likely a fools errand. It will receive copious amounts of bodily fluid in its short life. However, a well protected mattress can hold up over time if it is quality made.
The cheapest kid sets usually have ultra thin cotton fabrics and very little padding. Even if their body weight was supported at a young age and low weight, it won’t be adequate for long. They also have very cheap inner springs or foam cores which will not hold up over time.
The bottom line is that you get what you pay for and often it could be causing sleeplessness and back issues in some children. Children without adequate sleep or support will have back and spine issues, concentration issues, behavioral problems, scholastic issues, and so on.. What you save today will cost a lot more tomorrow.
A little more invested will net a lot greater return – starting with the fact that you won’t have to replace the mattress every few years. Do you and your kid a favor, don’t let them sleep on something inadequate and disposable. You will both be happier
