Choosing a crib mattress might not be as fun as selecting adorable nursery décor, but it’s one of the most important purchases you’ll make for your little one’s room. There are many options to consider before you buy—the type of the mattress, waterproof versus breathable, organic versus conventional—but if your purchase meets Health Canada’s guidelines for thickness and fit (more on that below), you really can’t make a bad call. So, take a deep breath, parents-to-be—this decision is easier than you think, and we’re here to help.

Durable innerspring mattresses feature a core of thick metal coils surrounded by cushiony upholstery. Pricier and heavier than other options, they have the best edge support and are the least likely to sag at the sides.
Polyurethane foam mattresses are lighter and less expensive than their counterparts. Look for the firmest model possible—ideally you want something that quickly regains its shape after being pressed down.
Also known as a 2-in-1, this style is firm on one side for an infant and slightly softer on the other side for a toddler. Dual or double-sided mattresses are meant to last through your little one’s early years.
All mattresses sold in Canada need to follow government regulations[1] for fit and firmness. Beyond that, here are some other features you may wish to look for:
Health Canada has several safety guidelines for choosing and using a crib mattress:
With 150 durable steel coils at its core, this lightweight mattress offers even firmness and support and features two hypoallergenic layers for comfort. This standard-size mattress is also antibacterial and the waterproof lock-stitched binding prevents mould, mildew and odours from setting up shop. It’s Greenguard Gold certified for its low chemical emissions and made without flame retardants.
With thousands of five-star reviews, this durable Safety 1st foam crib mattress is a Walmart fave. It’s made from a thermo-bonded fibre core that has firm support for safer sleep. It also features a waterproof, stain-resistant vinyl cover that easily wipes clean in case of diaper leaks or spit-up. Add a 10-year limited warranty and this mattress is a total winner.
Dual, a.k.a. double-sided, mattresses save money in the long run. One side is extra firm for an infant, while the other side is softer for a toddler, so you can continue using it as your babe transitions from crib to bed. This resilient foam pick has enhanced airflow, is hypoallergenic and features a waterproof exterior that easily wipes clean, which is a must-have with little ones!
With a cover made from organic cotton—a.k.a. grown without the use of chemicals or pesticides—and a heat-bonded recycled polyester core, this mattress is a great choice for anyone looking for a breathable mattress that stays cool in the summer and cozy in the winter.
For use with a portable or mini crib, this high-density foam mattress offers the benefits of standard-size mattress but in a smaller format. This model is dual-sided, with breathable material on the infant side and a waterproof cover and lock-stitch seams (to keep leaky, messy situations away from the mattress’s core) for toddlers.
