Remember the good old days when mattresses were built like tanks and lasted for ages? Well, grab your nightcap and prepare for a bedtime story with a twist because we’ve cracked the code to bring those golden days back, and it won’t cost you a king’s ransom!

We teamed up with Spring Air in Surrey, BC, and let me tell you, they understood the assignment. They whipped up a mattress that’s fit for sleeping like a king but without the royal price tag. Introducing the Spring Air Cora mattress – your new best friend in the quest for glorious sleep!

Picture this: a mattress so ingenious, it’s got two sides! Yep, you heard that right. The Cora is a two-sided, symmetrical dream machine. It’s like the classic mattresses your grandparents raved about, with upholstery layers on both the top and bottom of the pocket coil spring system. Flip it, spin it, love it – it’s that simple!

Here’s the magic trick: by using both sides of the mattress, you’ll nearly double its lifespan. Yes, folks, it’s like getting two mattresses for the price of one! All you need is a plan to flip and rotate it regularly. We recommend alternating between flipping your Cora mattress and rotating it 180° every three months. Think of it as giving your mattress a little dance routine. Cha-cha-cha, baby!

Now, let’s talk about the cushy stuff. The outer fabric of the Cora is quilted with a plush fibre blend and ECOTEX™ gel foam, with an extra layer of ECOTEX™ foam on a fibre insulator pad. And guess what? It’s the same cozy goodness on both sides!

At the heart of this flippable wonder is a 5-zone, 8-inch individual pocket coil spring unit. These coils are like little bodyguards, offering top-notch pressure relief and full-body support. And with a thicker wire gauge in the centre zone to help spinal alignment and a reinforced edge, you’re in for a sleep that’s not just deep but also firm where it counts.

So, if you’re ready to revolutionize your sleep and give your mattress the long life it deserves, the Spring Air Cora is your ticket to dreamland. Get ready to flip, rotate, and snooze your way to a happier, healthier you!
