Yes. Every single one of our mattresses complies with UK fire regulations BS7177 and are categorised as low hazard, for domestic use. So, you can sleep easy!

We a proud that the foam we use in our mattresses DOES NOT contain the recent defective ingredients supplied by BASF’s Ludwigshafen factory, which has affected other manufacturers.

We don’t fold or otherwise change the shape of our mattresses we simply roll them, so the box dimensions will depend on the size you order.

Single: 100x40x40cm
Double/King: 160x40x40cm
SuperKing: 190x40x40cm

The Mammoth sport mattress is a comforting 22cm deep. In our experience, most sheets will fit beautifully over this depth. You’ll be ready to get the best night’s sleep before you know it.

Well, of course we’d say our mattresses are just right. But to be more specific, our mattresses are a medium firmness. The support and comfort offered by a Mammoth Sport will feel tailored just for you. It’s not too firm, not too soft. But most importantly it will support you all the way through the night.

The maximum weight per person is 20 stone (127kg).

When someone moves during the night, something called kinetic energy is generated. On a bog-standard mattress, that energy is transferred through the mattress and can disturb your partner.

Mammoth’s PostureCell™ technology absorbs that kinetic energy, minimising any disturbance and allowing you both to sleep soundly.         

The Mammoth sport mattress sits at a comforting 22cm. Most sheets will fit this depth.

Quite the opposite! Mammoth’s Medical Grade Foam is not temperature sensitive and doesn’t retain heat like memory foam. It has been specifically designed with cooling airflow channels to help you stay at the optimum temperature for sleep. We’ve thought of everything!

Ours is a no-questions-asked warranty. If your mattress fails within 10 years because of a manufacturing fault, we’ll take it away and deliver a brand new one for you. Could you ask for anything more?

That’s how confident we are that your mattress will last. You’re covered for flaws introduced in the manufacturing process, even in the cover. However, wear and tear and damage done whilst moving house (for example) are not covered.

This is a matter to discuss with your courier. Try using your courier’s tracking service to find out if that’s an option.

Unfortunately, we do need a signature to guarantee the safe delivery of your mattress. After all, we’d hate for anything to happen to it before you get a chance to lie down and really sample its delights.

We’ll let you know the contact details of your courier once we’ve dispatched your order.

You’ll receive tracking details from us once your order is on its way to you. Simply access the courier’s tracking system, enter your details and you’ll be able to see the progress of your order. Exciting.

If you aren’t in when your mattress arrives, the courier will try to deliver again another time. They’ll put a card through your door letting you know how to get in contact and you can arrange another time, more suitable for everyone.

All returns are absolutely free.

All you have to do is remove your bedding and our returns courier will take the mattress away for you

Unfortunately, exchanges aren’t accepted. However, if you’re within the returns period stated on our website, you are able to return your items and reorder new ones.

We’ll always try to make sure old mattresses are recycled where appropriate.

You’ll return your mattress to us, via a courier. Once we have the mattress back we’ll start the refund process. This will happen via the original payment method so keep an eye on your accounts for the next 3-5 business days and you’ll see your refund appear

We try to make the returns process as simple as possible.

Get in touch with us, let us know why you aren’t happy and we’ll arrange to have your items collected on a convenient date.

Simply open the box and remove the mattress in its packaging. Lay it out on your bed frame going width ways from side to side. Gently open the packaging along the seam, taking care not to use a sharp object that may snag the mattress cover. The mattress will unroll. Then you just need to put it into place on the bed and allow it to expand to shape. Once ready hop on and start your sleep journey with us.

Your Mammoth Sport will be happy wherever you put it. Ideally, a new mattress deserves a new base but if you already have a bed base you’d like to use, go ahead – as long as it’s the same size as your new mattress.

Ideally, sleep on your new Mammoth Sport for 30 nights to get used to the difference it makes. If you’re still not happy, contact our team to talk about the next step.

All foam mattresses may have a slight new car smell when they are first opened. This is perfectly normal and safe. The smell usually vanishes quickly, airing the mattress can speed this up. Some people are more sensitive to the smell, but again, it is totally safe.

Of course. Simply use a soft, damp cloth to wipe your cover while it’s still on the mattress. There’s no need to remove the cover from the mattress. Use small circular motions with the cloth to remove marks most effectively

It’s not essential, but we’d recommend the use of a protector to keep your Mammoth Sport looking good as new.

Yes, that’s no problem at all. But you’ll find that, once you’re settled in bed, your Mammoth Sport will keep you at the optimum temperature for a restful night’s sleep, night after night.

We’ve all dreaded that annual job of flipping the mattress. But the good news is, there’s no need with the Mammoth Sport. We recommend that you simply rotate the mattress regularly to ensure even usage.
