Whoa! This CostCo mattress is £50 cheaper than at Argos!

CostCo mattress range? Not the first place that pops into our minds for quality, but Silentnight's top rated memory foam mattress is a steal there

In the market for a mattress deal? Did you know the CostCo mattress range is really very good – and that the prices are unbelievable? Let's focus on this one: Silentnight's Now 5 Zone Rolled Memory Foam Mattress, which is on sale for £149.89. Compare that to Silentnight's Memory Foam Rolled Double Mattress on sale at Argos for £199, and that's a £50 (minus 89p) saving. 

What's to like about this mattress? The Silentnight 5-Zone has a high density memory foam layer (think super comfortable) a zoned core (as the name would suggest) to offer bags of support. And it's all wrapped up in a quilted anti-allergy cover for the dust mite allergic. It arrives rolled (so, easy to get up the stairs whether you're in a house or a flat), and has a five year warranty. We like. Click the links above to buy.
