A Simba mattress protector works like a breathable insurance policy for your mattress. It sits between you and the mattress surface, catching the sweat, dust, skin cells and everyday spills that would otherwise work their way into the comfort layers. Unlike traditional plastic-backed covers, Simba mattress covers have a breathable cotton surface with soft cushioning, so air keeps moving through the bed and the protector adds comfort rather than taking it away.
Be clear on what a Simba mattress protector does and doesn't do. Its surface resists small spills long enough for you to deal with them, but it isn't fully waterproof. If you need protection against larger spills or night-time accidents, for example on a child's bed, a dedicated waterproof design from our wider mattress protector range is the better choice.
Using a protector is one of the simplest ways to prolong the lifespan of a Simba mattress, or any other mattress. Keeping the surface clean and dry helps the materials underneath perform as they should for longer, and a washable cover is far easier to keep fresh than the mattress itself. Simba sources its cotton through the Better Cotton Initiative, and the brand holds B Corp certification for its social and environmental standards.
Simba mattress covers are made in a fitted-sheet style, with a deep elasticated skirt and four-way stretch. They fit mattresses up to 40cm deep, which covers most deep hybrid and pocket sprung mattresses, and the snug fit helps stop the cover pulling away at the corners when you move in the night.
If you use a mattress topper, measure the combined depth of your mattress and topper before ordering. As long as the total sits within 40cm, the protector can go over both.
| Size | Dimensions | Best For |
|---|---|---|
| Single (3ft) | 90 x 190cm | Children's rooms, guest beds, solo sleepers |
| Small Double (4ft) | 120 x 190cm | Solo sleepers wanting more space, compact rooms |
| Double (4ft 6) | 135 x 190cm | Couples, guest rooms, smaller main bedrooms |
| King Size (5ft) | 150 x 200cm | Couples wanting extra width and length |
| Super King (6ft) | 180 x 200cm | Larger main bedrooms and deep, wide mattresses |
Every size fits a mattress depth of up to 40cm. Measurements are approximate, with a tolerance of plus or minus 2cm.
Because these are standard UK sizes, Simba mattress covers fit mattresses from any brand, on any bed frame or divan, as long as the mattress size matches. If you're updating the whole setup, browse our full range of beds.
Every Simba mattress cover is machine washable at up to 40°C and can be tumble dried on a low heat, so you can wash it at home alongside the rest of your bedding. Its anti-dust mite treatment is designed to be wash-resistant, so it keeps working after regular washes.
For general hygiene, wash your protector every one to two months, or more often if anyone in the household has allergies. Always check the care label before washing, and avoid ironing or high heat. For more on keeping your bed fresh, read our guide on why you need to get that bedding washed.

| Question | Answer |
|---|---|
| What is a Simba mattress protector? | A Simba mattress protector is a removable, washable cover that fits over your mattress like a fitted sheet. It shields the mattress from sweat, dust, dust mites and everyday spills, and adds a soft, cushioned layer on top. Because you can take it off and wash it at home, it keeps your sleeping surface fresh without you needing to clean the mattress itself. |
| Is a Simba mattress protector waterproof? | No, it isn't fully waterproof. Its surface resists small spills long enough for you to wipe them up, which suits most adult beds, but liquid can soak through if it's left to sit. If you need full waterproof protection, for example on a child's bed or for night-time accidents, choose a dedicated waterproof protector from our mattress protector range. |
| Can you wash a Simba mattress protector? | Yes. Simba mattress protectors are machine washable at up to 40°C and can be tumble dried on low. Always check the care label first, and avoid ironing. |
| How often should you wash a Simba mattress cover? | Every one to two months is a good routine for general hygiene. If you or anyone sharing the bed has allergies, wash it more often. Stick to a maximum of 40°C in a standard domestic washing machine. Some allergy advice recommends washing bedding at 60°C, but that would be too hot for this protector. Its anti-dust mite treatment is designed to keep working through regular washes at 40°C. |
| How do I use a Simba mattress protector? | Pull it over your mattress like a fitted sheet, tucking the elasticated skirt under each corner. It works best directly on the mattress, so put your fitted sheet on top, then your duvet and pillows as normal. |
| Do Simba mattress covers make noise or feel hot? | They're designed to give a soft, quiet sleeping surface. The top layer is breathable cotton rather than the plastic finish some protectors use, so there's no crinkling when you move, and air can keep circulating to help prevent overheating. If you sleep very hot, pairing your protector with breathable bedding such as a cooling duvet helps. |
| Will a Simba mattress protector fit non-Simba mattresses? | Yes. Simba mattress protectors come in standard UK sizes from single to super king and fit mattresses up to 40cm deep, so they work on mattresses from any brand. Just make sure you choose the same size as your mattress. |
| What guarantee comes with a Simba mattress protector? | Simba mattress protectors come with a 1-year guarantee. Check the product listing for full details before you order. |
| Do you offer free delivery on Simba mattress protectors? | Free delivery applies to most UK mainland postcodes on orders over £100. Orders under £100 carry a small delivery charge, and some remote postcodes may incur an extra charge. Estimated lead times are shown on the product listing. See our delivery page for full details. |
| Can I buy a Simba mattress protector on finance? | Yes. Klarna Pay in 3 is available at checkout, subject to status, and finance options are available on eligible orders. See our finance page and Klarna page for full terms. |
