📐 Mattress Thickness Guide: Why Thickness Matters (and When Thin Just Won’t Cut It)
The ideal mattress thickness depends on who's sleeping on it. While 5–7" may work for kids or bunk beds, most adults need 8–12" for support. For luxury comfort or joint pain relief, 12–15"+ is ideal.
What Is Mattress Thickness?
Mattress thickness (also called mattress depth or height) refers to how many inches tall your mattress is from base to top. It affects how soft, firm, supportive—or disappointing—your sleep will be.
Mattress Thickness Chart (Quick Breakdown)
Thin Mattresses (5–7”): Not Always a Win
These are typically budget mattress options for bunk beds, trundle beds, or kids under 8. They can be fine for short-term sleep, but don’t expect long-term back support.
Use if:
- Your child is small and light
- You're outfitting a sleepover space
- You hate your in-laws just a little (kidding... sort of)

This range hits the sweet spot between price and comfort. Most of our best mattress options for adults land right here—especially in Queen and King sizes.

Yes, thicker mattresses are often more expensive—but when it comes to health and comfort, it’s one of the smartest investments you can make.
Children’s Sleep & Mattress Thickness
Let’s get serious for a sec: children’s sleep is about more than just naps and bedtimes. A good mattress can help kids feel safe, supported, and well-rested. As someone who is a former foster parent, making a child feel safe and be life changing for that child.
If you're helping a child settle into a new home, avoid super-thin, low-support beds. Choose a curated mattress that’s thick enough for real rest and soft enough for comfort.
