King Size Mattress Guide: Prices, Deals & How to Find the Best One in Canada

When it comes to upgrading your sleep, nothing says comfort like a king size mattress. Whether you’re tired of cramped nights on a queen size mattress or you’re finally ready to bring that luxurious hotel-style feel into your bedroom, a king mattress offers the space, support, and quality you deserve.

But with so many options out there, different prices, materials, firmness levels, it’s easy to feel overwhelmed. Don’t worry, we’ve done the homework for you! This guide will break down king size mattress prices in Canada, sales and deals worth checking out, and how to choose the right king mattress for your sleep style.

At National Mattress, our mission is simple: make better sleep more affordable and stress-free. Let’s dive in.

Why Choose a King Size Mattress?

Think of a king mattress as an investment in both space and comfort. Measuring approximately 76 inches wide by 80 inches long (193 cm x 203 cm), it’s the largest standard mattress size available in Canada.

Benefits of a King Mattress:

• More space for couples – No more elbow wars at 2 a.m.

• Family-friendly – Room for kids or pets to hop in without crowding.

• Luxury sleep experience – King beds are the centrepiece of a bedroom, offering hotel-like comfort every night.

If you’ve ever woken up feeling squeezed on your current mattress, upgrading to a king may be the ultimate solution.

King Mattress Sizes in Canada

In Canada, mattress dimensions are standardized, but here’s a quick refresher:

Pro tip: If you live in a smaller home or condo, make sure your hallways and doorframes can fit a king mattress. We often recommend a split king (two twin XL mattresses side by side) for tighter spaces.

Firm vs. Soft: Finding the Right King Mattress for You

Mattress firmness is where sleep science meets personal preference.

• Firm King Mattress – Best for back sleepers, people with lower back pain, or anyone who likes extra support. (Check out the Chirofoam XF Extra Firm Memory Foam).

• Medium Firm – The most versatile choice, good for couples with different sleep styles. (Our Beautyrest BeautySleep Euro Top is a perfect example).

• Soft/Plush – Great for all sleeping positions or anyone who prefers more pressure relief. (Check out the SEALY® Posturepedic® Natural Origins 16" Plush Euro Top Latex).
