Choosing the perfect cot mattress can feel a little overwhelming. Foam or spring. Firm or soft? Will it fit the cot? Is it even safe?
We get it. That’s why we’ve created this simple guide to help you pick the right mattress for your little one. Whether you’re a first-time parent or adding another tiny human to the family, we’ve got you covered, the Aussie way.
What Makes a Mattress Safe for Babies?
Let’s start with safety. For newborns and toddlers alike, a mattress should be:
- Firm and flat. No sinking or slouching.
- Snug-fitting in the cot. No gaps around the edges.
- Free from harmful chemicals.
All GroTime mattresses meet Australian and New Zealand safety standards, so you can rest easy knowing bub’s bed is built for safe, supportive sleep.
Foam vs Spring. What’s the Difference?
Let’s compare your options.
- Foam mattresses, like our M690F100C Comfort Foam, are soft, lightweight, and ideal for newborns. Plus, they’re super easy to clean.
- Spring mattresses, like the M760S100 Breathe Easy, give more structured support, perfect for wriggly toddlers or growing little legs.
Not sure which one to choose? Foam is great for the early months, while spring is ideal if you want a mattress that grows with your bub.
How Do I Know It Will Fit My Cot?
All GroTime mattresses are designed to fit specific GroTime cots, including: Crescent, Helsinki, Norway, Elara, and more.
Just check the product listing for compatibility, or head to our mattress collection to explore by cot model.
Not using a GroTime cot? No worries. Simply measure the inside of your cot and compare it with the mattress dimensions online. If it fits snugly, you’re good to go.
How Do I Keep It Clean?
Spills and accidents? Totally expected. Most Grotime mattresses come with:
- Removable zip-off covers
- Moisture-resistant layers
- Machine-washable fabrics
So, when mess happens (and it will), just unzip, toss in the wash, and you’re back in business.
How Firm Should It Be?
While soft might seem comfy, babies need a firm, flat surface to support safe sleep. All our mattresses are tested to meet firmness standards in Australia and New Zealand, so they’re baby-approved and parent-trusted.
Do I Need a Different Mattress as My Baby Grows?
Not necessarily. Many parents start with a foam mattress for the newborn stage, then switch to a spring option when their bub starts sitting, standing, or bouncing like a tiny kangaroo.
If you’re after a long-term option, choose one of our Breathe Easy Spring mattresses. They’re built to last through toddlerhood.
Which Mattress Size Do I Need?
Here’s a quick guide:
- For compact cots, try the M630S100 or M660S100.
- For standard GroTime cots, choose the M690S100 or M760S100.
Just check the size of your cot base before you buy. A snug fit is key to safe sleep.
Why Choose a GroTime Mattress?
- Designed and tested in Australia.
- Family-owned with four generations of care.
- Breathable, easy-clean materials.
- Made to match Grotime cots perfectly.
- Backed by a 12-month warranty.
When you choose a GroTime mattress, you’re not just buying baby gear. You’re investing in quality, comfort, and Aussie-trusted safety from day one.
Choosing the right cot mattress doesn’t have to keep you up at night. The key things to remember are to always choose a firm, supportive mattress rather than a soft or squishy one, make sure it fits your cot’s measurements correctly, and select an option that best suits your family’s needs and lifestyle. With the right fit and support, you can create a safe and comfortable sleep space for your baby.
Whether you’re nesting for the first time or simply upgrading, we’re here to help you make the best choice for your bub’s sleep, safety, and smiles.
