FAQS

our 7 most popular questions, answered

  • What makes a Mio mattress so blissfully comfortable?

    It’s the unique way we combine our different foams. A durable base foam provides a firm foundation and a transition foam distributes weight.

    Above that, memory foam moulds to your body for unwavering support, while just the right amount of Adaptive foam over the top keeps things springy and keeps you cool. Perfect.

  • Do I really have 100 nights to decide?

    Yes. Order a Mio and if, within 100 nights, you don’t think it’s the best mattress you’ve ever, ever slept on, let us know. We’ll come and collect it and provide a full refund.

  • Why should I try Mio for at least 14 – 30 nights?

    Because your body needs at least that time to adjust to a new sleeping surface. You’ve probably been sleeping on a mattress that’s been gradually breaking down over a number of years, and you’ve become accustomed to that poor sleeping posture. On a Mio mattress your back will become naturally aligned and your body fully supported overnight, forcing dormant muscles into action. It’s bit like returning to the gym after a break from exercise. Such a drastic change sometimes takes a little while to get used to. If you don’t give Mio at least 14 –
    30 days, you may never realise the huge difference it can make.

  • How does a Mio mattress feel?

    Wonderful. And it’s not just us saying that. 25 years in the mattress industry has taught us that almost everyone wants a sleeping surface that’s firm but not too firm, bouncy but not too bouncy. So that’s exactly what we’ve designed Mio to provide.

  • Do I need a particular type of bed base for a Mio mattress?

    Mio works perfectly on all types of bed base and any flat surface – including the floor.

  • Do you have a showroom?

    There’s really no point. The only way to know if Mio is right for you is by sleeping on it, and you can’t do that in a showroom. Instead we’ll ship it to you for free and give you 100 nights to put it to the test.

  • Why is Mio cheaper than the mattresses in high street stores.

    Simple. It’s because we don’t have any overheads like high street stores. We manufacture Mio and then we deliver it direct to your door. There’s nothing in between. We think it’s only fair that the savings are reflected in the price.

Mio’s Materials & Construction

  • Does the foam smell?

    Just like with any new product – a sofa, a rug – you’ll be aware of a new scent when you open the box. But the scent is mild and, in a well-ventilated room, will dissipate quite quickly. Some people are more sensitive to smell than others, and if that’s the case, then a light spray of Fabreeze may help to speed things up. Further information can be found here.

  • What kind of materials is Mio made from?

    Mio hybridises four layers of foam: a dense base layer, a movement-smoothing third layer, a supportive memory foam second layer, and a springy, Adaptive top layer. And since bed should be a safe place, all four are high quality and Certi-Pur® rated. Which means they’re free of chemicals and toxic materials.

  • Does the Mio mattress transfer movement?

    Mio provides great motion isolation. The energy-absorbing properties of memory foam coupled with our Adaptive foam mean that if your restless partner is more than finger span away you should neither feel or hear their movement. If they move, you won’t move with them. Unless you want to.

  • How will Mio compare to my memory foam mattress?

    It’ll feel similar but better. High-grade memory foam provides great support. But when used as a top layer it retains the heat produced by your body, and this can cause restless sleep. There’s also a tendency to sink into a memory foam mattress to the point of feeling stuck.

    Mio has a layer of springy, breathable, Adaptive foam over the memory foam layer that adds a level of elasticity and allows you to move around more freely. It’s great, you should try it.

  • Can one mattress really suit all?

    Perhaps not quite all, but certainly most. Mio was designed to provide the level of support, comfort and bounce that we know most people look for in a mattress. If you prefer an excessively hard or supremely soft sleeping surface, it may not suit you. But then again, it might. With 100 sleeps to decide there’s every reason to give it a go.

  • Does it retain heat like a memory foam mattress?

    Mio’s top layer of new generation Adaptive foam is completely breathable, so it draws the heat away from your body and also allows air to pass beneath you. Foam does sleep a little warmer than some other surfaces, but Mio is as cool as we can make it.

Shipping & Delivering Mio

  • When should I expect delivery of my mattress?

    Your Mio mattress is made to order and will be delivered free within 5 – 7 working days. Once we’ve dispatched your mattress you’ll receive a confirmation email and usually a text message too.

    If you’re purchasing a Mio to replace your existing mattress, we recommend that you don’t dispose of your old one until your new one arrives – just in case. We’d hate it if you had to sleep on the sofa.

    We make every effort to deliver your Mio mattress within 6 – 7 working days (it may take a little longer in the Scottish Highlands). However, this is Britain, and unforeseen delays such as traffic or bad weather do sometimes occur.

  • Do I need to be home to accept delivery.

    Due to the high value of Mio, a signature will be required. If nobody’s home, no problem. We’ll just reschedule your delivery for another day.

Returns

  • How do I pack my mattress to return it?

    You don’t need to. We’ll remove the mattress from your home and donate it to a local charity or take it to be recycled. We just ask you have it ready and waiting by the door.

  • What is the return and refund policy?

    You have 100 nights to put your Mio to the test. If you’ve not fallen in love with it by then, we’ll come and collect it and refund you in full.
