Sleep Well For Less - Last Chance
A double mattress protector measures 135 x 190cm and fits directly over a standard double mattress, sitting between the mattress and the fitted sheet. Its job is straightforward: protect the mattress from moisture, sweat, allergens, and general wear - and by doing so, extend the life of the mattress and keep most manufacturers' warranties valid. Our double mattress protector range covers waterproof, cooling, bamboo, copper-infused, cotton, and quilted options from a range of trusted brands, with guarantees from 1 to 12 years. Free delivery on orders over £100 and expert advice seven days a week.

A mattress is one of the most significant purchases most people make for their home - and one of the least maintained. Without a protector, a double mattress absorbs sweat, body oils, dust mites, and allergens night after night. Most mattress manufacturers require a protector to be in place for the warranty to remain valid - a fact that most people only discover after something goes wrong.
A double mattress protector creates a washable barrier between the mattress and the sleeper. It catches what would otherwise be absorbed permanently into the mattress filling, can be removed and machine washed regularly, and in doing so extends the hygienic life of the mattress significantly.
For a double bed shared by two people, the case is stronger still. Two people sleeping on the same mattress every night generate more moisture, more heat, and more allergen exposure than a single sleeper. A protector that breathes well, manages temperature effectively, and washes easily is a practical necessity rather than an optional extra.
The range covers several distinct types - from basic waterproof options through to thermoregulating, bamboo, copper-infused, and quilted designs - each suited to different priorities. For a full guide, see our buying guide: Ultimate Guide to the Best Mattress Protectors.
| Factor | Why It Matters | What to Check |
|---|---|---|
| Waterproofing | A waterproof layer protects the mattress from spills and moisture that would otherwise be absorbed permanently. Essential for anyone who sweats during the night, has young children, or has a mattress with a long guarantee they want to keep valid. | Check whether the protector is fully waterproof or water-resistant. Fully waterproof uses a membrane barrier. Water-resistant slows but does not stop penetration. |
| Temperature management | A double bed shared by two people generates significant heat. A protector that traps warmth can make the mattress sleep uncomfortably hot. Cooling, bamboo, copper-infused, and thermoregulating options actively manage heat at the sleep surface. | If you or your partner tend to sleep warm, look specifically for cooling features in the protector specification. |
| Fit and mattress depth | A protector that does not fit the mattress correctly will shift during the night, bunch under the sheet, and fail to protect the full mattress surface. Mattress depth varies significantly - particularly when a topper is added. | Check the protector's pocket depth against your mattress - and the combined depth if you use a topper. |

| Type | What It Does | Best For |
|---|---|---|
| Waterproof | A membrane layer prevents liquids penetrating the mattress surface. Usually breathable rather than plastic - modern waterproof protectors are quiet and comfortable to sleep on. | Anyone who sweats at night, those with young children, protecting a premium mattress, keeping warranty valid |
| Cooling / Thermoregulating | Uses specialist fibres or phase-change materials to draw heat away from the sleep surface and maintain a more consistent sleeping temperature. | Hot sleepers, those sharing a bed who generate significant heat, those with memory foam mattresses that already retain heat |
| Bamboo | Made from bamboo-derived fibres. Naturally breathable, moisture-wicking, and hypoallergenic. Softer than cotton. Often combined with waterproofing. | Those wanting natural materials, allergy sufferers, those who sleep warm but prefer a natural fibre to a synthetic cooling solution |
| Copper-infused | Copper fibres woven into the fabric. Copper has natural antimicrobial properties and is claimed to support skin health. Usually combined with other performance features. | Those wanting antimicrobial properties alongside standard protection, those with sensitive skin |
| Cotton | A breathable, natural fabric protector. Softer and more traditional than synthetic alternatives. Usually machine washable at higher temperatures. | Those wanting a natural, breathable option at a practical price point, those who prefer familiar natural materials |
| Quilted | A padded protector with additional cushioning above the waterproof or protective layer. Adds a subtle comfort layer while protecting the mattress. | Those wanting additional surface comfort alongside protection, those with a firmer mattress who want a subtle softening layer |
The warranty length on a mattress protector is one of the most useful indicators of the manufacturer's confidence in its durability.
| Guarantee | What to Expect |
|---|---|
| 1 to 2 years | Standard entry-level and mid-range options. Reliable for everyday use. |
| 3 years | Premium specification. Found on higher-end thermoregulating and performance protectors. |
| 10 to 12 years | Found on the strongest-performing protectors in our range. Reflects genuine confidence in long-term durability and washability. |
Always check the individual product listing for the full terms and conditions of the guarantee.
Most mattress manufacturers require a mattress protector to be in use from the first night for the mattress warranty to remain valid. Check your mattress warranty documentation to confirm this requirement. A mattress purchased without a protector in place from day one may have its warranty affected if the mattress is later found to have absorbed moisture or allergens.

| Question | Answer |
|---|---|
| What size is a double mattress protector? | A double mattress protector is sized to fit a standard double mattress measuring 135 x 190cm. Always check the pocket depth on the individual product listing if your mattress is particularly deep, or if you use a mattress topper on top of the mattress, as the combined depth needs to fit within the protector's elasticated pocket. |
| Do I need a waterproof mattress protector? | Waterproofing is strongly recommended for anyone who sweats during the night, anyone with young children sharing the bed, and anyone wanting to keep their mattress warranty valid. Modern waterproof protectors use breathable membranes rather than plastic, so they are quiet and comfortable to sleep on rather than the crinkly sheets of older designs. |
| Does a mattress protector affect how the mattress feels? | A good quality protector should be barely noticeable. Thin fitted protectors have minimal impact on mattress feel. Quilted protectors add a subtle comfort layer. Avoid very thick or poorly fitted protectors that bunch under the sheet or create an uneven sleeping surface. |
| Can I use a mattress protector with a mattress topper? | Yes, but check the order. The protector goes on the mattress first, then the topper goes on top of the protector, then the fitted sheet covers both. This arrangement protects the mattress from the topper as well as from the sleeper. Some people also add a second protector over the topper for additional hygiene. |
| How often should I wash a double mattress protector? | Every one to two months is a reasonable guide for a protector in regular use, or more frequently if anyone in the bed sweats heavily or has allergies. Always check the individual care label for the maximum wash temperature - some protectors can be washed at 60 degrees (useful for allergy sufferers), while others require lower temperatures to maintain the waterproof membrane. |
| Will a mattress protector affect my mattress warranty? | In most cases it is the opposite - not having a protector affects the warranty. Most mattress manufacturers require a protector to be in use from the first night as a condition of the warranty. Check your mattress warranty documentation to confirm this requirement. |
| What is the difference between waterproof and water-resistant? | A fully waterproof protector uses a membrane that prevents any liquid penetrating through to the mattress. A water-resistant protector slows penetration but does not stop it entirely under sustained pressure. For genuine protection against accidents, night sweats, or spills, fully waterproof is the reliable choice. |
| Do you offer free delivery on double mattress protectors? | Yes, free UK delivery is included on orders over £100. Many individual mattress protectors fall below this threshold - check the individual listing for delivery charges. Some remote postcodes may incur an additional charge. See our delivery page for full details. |
| Can I buy a double mattress protector on finance? | Yes. Interest-free finance is available on eligible orders. See our finance page for full details on terms, eligibility, and how to apply. |
