There are all sorts of variables (read: miracles) that need to fall into place in order for us to get a good night’s sleep.

We’ve tried putting our phones away, getting black-out blinds and even played whale music (yes, whale music) before getting under the covers, yet good-quality shut-eye can still evade us.

Now we’ve learned that the key to a seamless slumber might lie with one bed accessory: a mattress topper.

Not just any mattress topper though, a Natural Cotton Quilted Mattress Protector from John Lewis & Partners.

Available in six sizes – from a small single to a super king – this naturally breathable protector has a pure cotton filling and quilted outer layer for ultimate comfort and super-softness.

Plus, it uses micro-fresh technology (no, we’d never heard of it before either) to prevent the growth of odour-causing bacteria.

And if you thought that mattress toppers were for old or second-hand mattresses, then think again. The soft cotton adds depth, warmth and a deeper feeling of indulgence to any bed – new or old.

And we aren’t the only sleep-hunters who think so.

The mattress-topper has received over 700 reviews on the high street retailer’s site, with well-slept shoppers calling it “high quality”, “perfect” and “great value for money”.

One reviewer praised the product’s ability to transform older mattresses: “Needed something to make a secondhand mattress more comfortable. This topper proved excellent value – good quality, snug fit and most importantly, it’s very comfortable.”

Another had given the gift of brilliant beauty sleep to her children: “This mattress is perfect for our daughters’ bunk beds. The girls have been sleeping really well on them and it’s comfortable for those nights where we have been called through for sleepy cuddles! Great price as well!”

We’re sure you’ll agree that it sounds, quite literally, dreamy.
