On delivery of your new mattress
Remove all plastic packaging, and dispose of it safely. To avoid the risk of suffocation, keep all plastic away from children.
Allow to air
Do not cover your mattress straight away. Allow it to air thoroughly for a few hours. Airing the mattress on a regular basis will help keep the comfort fillings and fabric fresh.
Register your mattress
We know you will be eager to get into bed but while you are letting your mattress air, visit mammothwarranty.co.uk and register your new mattress. This will extend the length of your warranty, giving you complete peace of mind.
This mattress contains framed spring units. This type of unit is edged with a metal rod that, if bent, will not return to its original shape. Please do not attempt to roll or fold your mattress.
Carefully pierce the outer wrapping of the mattress, and gently pull the plastic away from the mattress. Place the mattress on the bed where it will be located. The bottom of the mattress is easily discernable from the top of the mattress, so make sure it is the correct way up. Remove the bag from the mattress. Your mattress will take a few hours (maximum 24) to fully recover.
The comfort fillings in your mattress are designed to flex to your body contours. To avoid premature wear on the fillings we recommend that you rotate the mattress from head to foot every 3 months. Our mattresses do not need to be flipped. You may find that, even with regular turning, the area where most weight is concentrated will settle more quickly, causing slight depressions. This is entirely normal and will not affect support and comfort
Any loose threads should be cut away with a pair of scissors. Never pull the thread as this could cause stitching to come undone and result in damage to the fabric.
In the event of soiling on the mattress, it may be lightly sponged with a weak solution of soap and water. Never use detergents or chemical cleaners on your mattress. These can adversely affect the covering material.
How will my new bed/mattress be packed, and how do I unwrap it?
Firstly, find a friend to help you – mattresses can be heavy!
All our beds are wrapped in heavy duty plastic which can be recycled.
Mattresses are packed in 2 ways:
(i) Vacuum Packed and rolled:
- Carefully pierce the outer wrapping of the mattress, and gently pull the plastic
away from the mattress.
- Place the mattress on to the bed where it will be located. The bottom of the
mattress is easily discernible from the top of the mattress, so make sure it is the
correct way up.
- Remove the bag from the mattress.
- Your mattress will take a few hours (maximum 24) to fully recover
(ii) Packed flat:
- Place the mattress on the bed where it will be located.
- Remove the plastic wrapper.
After unpacking, what should I do?
We know you will be itching to get into bed, but the first thing you should do is register your guarantee at www.mammothuk.com/guarantee.
Alternatively, if the site is not accessible, please email firstname.lastname@example.org
Please also ensure you keep your receipt or Proof of Purchase somewhere safe.
You will need this in the event you need to report a complaint under your Guarantee.
Why does my new mattress smell?
Don’t you love the smell of new things? All mattresses are manufactured at the time of order and sealed in protective wraparounds to ensure perfect presentation upon arrival. Smells are good news as it means your mattress has been made freshly for you! Initial odours are common after removal of the protective packaging and are normal. Most people don’t even notice, but those with heightened senses may report a “foam” odour, or a damp or musty smell. On taking delivery, it is a good idea to leave the mattress to air in a well-ventilated room. Regularly airing your mattress ensures proper maintenance and will help dissipate any odours.
Others are more sensitive to smells than others. Whilst a mattress may always retain an inherent odour if you smell it at close quarters, you should notice that any smell which is noticeable when you enter a room has greatly reduced within 3 months, providing you have followed the instructions above.
My new mattress feels slightly damp?
This is a good sign – it means your mattress conforms to all UK Fire Regulations. You may notice that the surface of your mattress feels damp when it is unpacked. We are required to treat certain mattress fabrics with a harmless Fire Retardant at source, in order to comply with the Regulations. This material is salt based, which will absorb moisture. When weather conditions are humid, or there is a lot of rain, this effect will be exaggerated, and when the mattress is packed into a bag, condensation may form, causing a damp feeling on the mattress. The feeling of damp will disappear quickly and should not materialise again, unless your mattress is kept in a particularly humid room.
Do I need to turn my mattress?
Fortunately not! You should never “flip” your mattress, but you need to rotate the mattress regularly to encourage even wear.
You should rotate your mattress head to foot (180 degrees) every week for the first six months, and then once per month from that point.
Will I see “body impressions” in the surface of the mattress after I have used it?
We hope you do – if you don’t see a body impression, it may be a sign your mattress is faulty. Body impressions are a characteristic of quality mattresses working as they should by conforming to the shape of your body. You should expect to see impressions, sometimes described as settlement or “dipping”.
With regards to settlement, the Furniture Industry Research Association (FIRA) issue the following guidelines on settlement depth:
Depth of Settlement by age
0 – 6mths 6 – 12mths 12 – 24mths 24 – 36mths 36 – 60mths
2.5cm 3cm 3.5cm 4cm 4.5cm
When inspecting mattresses, FIRA will lay a levelling implement (level or string) and then measure the depth of settlement from the underside of this implement to the lowest point of any settlement. FIRA will classify settlement as a fault only if it is considerably outside of the above guidelines, and only if the customer has followed the correct care routine (rotation etc). Even if settlement is considerably outside of these guidelines, it will not necessarily constitute a fault. In this situation, The Foam Company Ltd will be guided by a FIRA inspection.
Natural fillings will be subject to a greater degree of settlement, and may result in patches of uneven wear and tear – again this is normal. You can make sure settlement is even by rotating the mattress as above.
Can I use my bed/mattress as a trampoline, or as a seat when using the phone?
No! Your mattress and bed are designed to be lied on, not sat on for long periods of time. If you do, you will notice uneven wear in the mattress Please don’t let the children (or adults for that matter!) jump up and down on the mattress!
My mattress is softer/firmer than when I purchased it?
Like a new pair of shoes, your mattress will soften after a period of time, particularly in the areas you lie (sometimes described as “dipping”). This is not a problem, and is actually a sign the mattress is working with the weight of your body. There is even a British Standard on this (BS3379:2005) If a mattress has been displayed in a shop as a “floor model” that mattress may have already been bounced on many times, and may feel softer than the new mattress you will be delivered. It can take a few weeks, even months, for the mattress to fully settle down.
Can I use a mattress Protector with my new mattress?
We recommend the use of a mattress protector in addition to the removable washable covers. Unfortunately, if a mattress is soiled in any way due to dropping a glass of wine for example, your Guarantee will be invalid, and a mattress protector helps prevent this.
Does my mattress feature a removable, washable cover?
Where your mattress features a removable, washable cover or integrated mattress protector, you are able to machine wash at 40 degrees. When you remove the cover/mattress protector, please remember that the product has been used, and therefore you may see signs of wear and tear that you would not otherwise see with a fixed cover product. You may see some slight damage to the sleeping surface, small indentations, discolouration or even small tears. All of these are considered normal wear and tear, and do not constitute a manufacturer’s fault.
If the label does not state “removable, washable cover” then you should not remove the cover under any circumstances. We occasionally use “zipped” covers that are not designed to be removed. Where the cover is not intended to be removed, the zip will be locked using a “cable tie” device. Please note that if you then remove the cover, your Guarantee will be void.
Do your products comply with the UK Fire Regulations?
All of our products comply with the appropriate legislation as detailed in The Furniture and Furnishings (Fire) (Safety) Regulations 1988. Certificates are available on request.
Where are your products made?
All of our products are manufactured in the UK, and 100% of our raw materials are sourced through UK based organisations.
What type of base or frame can we use with your mattresses?
We recommend you use your mattress with a new base supplied by us, for a longer life, and better mattress performance. Placing a new mattress on an old base may contribute to a fault developing within the mattress. When the mattress is being used on a slatted bedframe, we ideally recommend that the space between the slats is not more than 7.5cm to minimise uneven softening and settlement, and that there is a central support leg for double sizes and above.
I am using my mattress with an old frame, or a frame not manufactured by you. There is a gap around the edge and it looks as if your mattress does not fit?
We manufacture our mattresses to metric sizes as below (for standard sizes):
Single 90cm x 190cm (3ft x 6ft3)
Double 135cm x 190cm (4ft6 x 6ft3)
King 150cm x 200cm (5ft x 6ft6)
Superking 180cm x 200cm (6ft x 6ft6)
In line with BS 1334:1996 , we have a +/- 20mm size tolerance on all mattresses and beds. In addition, many bed frames are still manufactured using imperial measurements (which are in brackets above). These imperial measurements are larger than the metric equivalent (so a “double imperial” frame would be 137cm x 191cm). If you have purchased an imperial frame with a metric mattress, the frame is likely to be bigger and therefore there may be a small gap. We believe that once bed linen is in place, this will be more than suitable.
I feel I have a problem with my bed. Is it Guaranteed, and what do I do?
We provide a standard 1 Year Guarantee on all our mattresses, which protects you against Manufacturing Defects. If you then register your product within 1 month of purchase, we will extend this to our 10 Year cover (5Year Guarantee + 5 Warranty). If you feel your product develops a fault within the period specified on the label of your mattress, please follow the below process. However, please read this document to make sure what you believe is an issue, is not actually normal before making getting in contact.
Please also note that the Guarantee/Warranty does not cover:
- A normal increase in softness in the polymer filling material or a decrease in the
slow recovery performance, which does not affect the pressure relieving properties.
- Any smells relating to the mattress
- Body indentations relating to normal settlement
- Level of perceived comfort
- Where a product has been purchased online, and the complaint is due to the “feel”
of the mattress
- Where the mattress has had more than 1 owner
The guarantee covers any deterioration, which causes the mattress to have a permanent indentation of considerably more than the guidelines issued by FIRA as referred to in point 6.
The guarantee will cease to apply if The Foam Co. Ltd finds that during the guarantee period, any of the following applies:
- Abuse, misuse, or general wear and tear
- The mattress has been used on a slatted base with slats more than 7.5cm apart
- Any causes other than faulty manufacture or materials
- Where the product is soiled, has become wet, or in an unsanitary condition
- Where the customer care hints detailed in this document have not been applied – this
includes not rotating the mattress as recommended
- Where the cover has been removed where the label does not state “removable, washable cover”
- A new mattress has been used with an existing, damaged divan or a divan that is
deemed to be of unsuitable quality
In order to register your concern, you will need to report the problem in writing to the retailer from whom you purchased the bed and they will handle your guarantee claim on your behalf and liaise with us. You will need to provide your Proof of Purchase in order for us to investigate your issue under your Guarantee.
Should your retailer no-longer be in business, or you feel that they are not assisting you, then please contact our customer service team on 01235 529148 and have the following available – proof of purchase, including date of purchase, product name and size plus description of problem. Our experienced team will give you an opinion on your issue. If your issue is covered by the FAQs, but you wish for us to arrange an inspection via a Third Party, we are able to instruct the Service Team of the Furniture Industry Research Association (FIRA) who are completely independent and linked to the Furniture Ombudsman. We will ask you to pay £50 for this service by Credit Card – in the event that FIRA deem the mattress to be faulty, we will repair or replace the mattress in line with the below, on a like-for-like basis (or for an equivalent specification in the event your product is discontinued) and refund your £50
5+5 Year Limited Guarantee Mattress replaced free of charge if the fault is reported within
5 Years of your purchase.
After that, a pro rata amount of your original purchase price will apply as follows
Year 6 20% of the purchase price
Year 7 40% of the purchase price
Year 8 60% of the purchase price
Year 9 – 10 80% of the purchase price
