Almost as good as their title, I ordered on a sunday evening and could have opted for a delivery two days later but opted for the wednesday. They acknowledged my order and kept me in touch all the way along. By the way, their price was unbeatable and the blue light discount was much appreciated. The deliverers were also on point and landed within the two hour delivery window. My extras were delivered, the old mattress removed and the new silentnight one taken upstairs to the bedroom of choice.It hardly took them five minutes, so speedy.However, I think mattressnext day are missing out on going the extra mile for absolute customer satisfaction. When you pay extra for mattress removal and delivery to room of choice, they would get so much kudos and brand loyalty from the simple act of removing the plastic sheeting to exhibit the new mattress in all its glory! some customers a little older than us would struggle somewhat in doing it themselves. Just a thought.

About Coolflex®

Very few brands of mattresses manage to achieve Trustpilot five-star reviews across the entire range, but Coolflex® is the exception. Whether it's an entry-level Essentials or their top-of-the-range ProAdapt™ memory foam mattress, this UK-based brand delivers outstanding performance, with a host of glowing reviews from the people who matter the most – their customers. 

They combine a superior quality alternative to memory foam for orthopaedic levels of support with technology that keeps you cooler all night long. And these mattresses also come boxed and rolled, so they’re easy to transport. 

What types of Coolflex® mattresses are available? 

At MattressNextDay, we’re delighted to bring you a selection of the best Coolflex® mattresses. Our up-to-date collection includes:

  • The Coolflex® Hybrid CHILL Mattress - This Mattress offers a luxurious and supportive sleep experience, featuring cooling technology, pressure-relieving foam layers, and individually pocketed springs to ensure temperature regulation, body alignment, and undisturbed sleep for you and your partner.
  • Coolflex® Pocket Plush 2000 Memory Mattress – Now we're talking luxury. This gorgeously comfortable medium mattress has a snuggle factor of 11, with cushioned ProAdapt™ foam and ProPedic™ pocket springs all rolled into one (literally – it comes boxed and rolled!). This one's suitable for all sleepers, whether you prefer to snooze on your back, front or side.

  • Coolflex® Hybrid ICE Mattress - With cooling gel layers, this is THE mattress for hot sleepers. Actively drawing heat away from your body, this medium firm, orthopaedic mattress keeps you at the optimal sleeping temperature all night long. Forget night-time overheating and sweating, as the luxurious pillow top contours to the unique curvature of your body, cooling it down wherever it touches you.

What are Coolflex® mattresses?

Coolflex® mattresses are an alternative to the standard memory foam mattress. The trouble with most memory foam is it simply doesn’t provide enough support to give you relief from back pain. How Coolflex® differs is that it uses its very own and specially designed reactive memory foam that’s denser than normal. This means you get more support and greater comfort.

The use of a dense foam means that you get that cushioned support all along the body, eliminating pressure points and cradling you so that your spine is held in a neutral position. Because they come in various firmness ratings, you have more choice, too. The fact that some are also hybrid mattresses also gives you the added advantage of a sprung core filled with individually pocketed springs. This provides even more responsive support, as well as minimising movement transference. So you and your partner get a great night's sleep, even if one of you is a bit of a wriggler!

The name Coolflex® also gives you a clue as to their other big plus – that ability to keep you cooler. Foam mattresses tend to feel a little hot due to the density of the foam. However, Coolflex’s Removeable AirFlo™ Cover actively draws heat away from the body, and the use of pocketed springs in some of their mattresses encourages even greater airflow. The result? A cooler, fresher feel and no more throwing the covers off when you get too hot!

By using state-of-the-art materials and manufacturing processes, Coolflex® mattresses provide you with a better night’s sleep at an affordable price. 

What is a Coolflex® mattress in a box?

Forget struggling with a full-size mattress up a tight set of stairs; a Coolflex® mattress in a box is the answer. Because of how they are designed and the materials used, Coolflex® roll-up mattresses can be vacuum-packed, rolled up, and popped into a cardboard box that one person can carry. Simply take your mattress in a box to your bedroom, unbox it, and remove it from the packaging. A Coolflex® boxed mattress will unroll and start to regain its original shape. In just a few hours, you have a full-size mattress, exactly where you want it and ready to sleep on. The box is recyclable. If you want to know more about memory foam mattresses, look at our Guide to Memory Foam Mattresses.

What sizes do Coolflex® mattresses come in?

Coolflex® mattresses come in various sizes to suit all types of beds. The single mattress size measures 3'x6'3", a small double mattress is 4'x6'3", and a standard double is 4'6"x6'3". You can upgrade to a king-size mattress at 5'x6'6" or go supersized with the super king at 6'x6'6".

How fast are Coolflex® mattresses delivered?

At MattressNextDay, we know you can't wait to snuggle up on your brand-new Coolflex® mattress. So we offer free next-day delivery to UK mainland destinations. If a next-day delivery doesn't suit your plans, then don't worry. You can pre-book a specific delivery date up to four weeks in advance. Check out our delivery page for more details, or give one of our friendly team a call.

What warranty does my Coolflex® mattress come with?

A Coolflex® mattress is a real investment. But to give you a little extra peace of mind, all Coolflex® mattresses come with a manufacturer's warranty. The Coolflex® 5-year guarantee means that in the unlikely event of a defect during that period, they'll repair or replace your mattress free of charge (at their discretion).
