Tell me more about the Simba TripleShield Bamboo Mattress Protector
The Simba TripleShield Bamboo Mattress Protector is a waterproof mattress protector made from soft, breathable bamboo jersey fabric.
It's built with Simba's TripleShield technology, a barrier layer tested to the BS EN ISO 208 waterproofing standard.
This means spills, sweat, and accidents are fully blocked from reaching your mattress, rather than simply being slowed down.
The bamboo jersey surface is thin, lightweight and silky to the touch, so it won't add any noticeable bulk once fitted, and you won't hear it crinkling underneath your sheets either.
We'd recommend the Simba TripleShield Bamboo Mattress Protector to anyone who wants a soft feel and genuine waterproof protection at an affordable price.
Reasons to buy
Genuinely waterproof, tested to BS EN ISO 208 |
|
Affordable price point |
|
Soft, breathable bamboo fabric |
|
Elasticated for a perfect fit |
Reasons to avoid
No quilted cushioning for a plush feel |
Simba TripleShield Tencel Cool Mattress Protector
- TENCEL fibre surface with TripleShield waterproof technology
- Fits mattresses up to 40 cm deep
Tell me more about the Simba TripleShield Tencel Cool Mattress Protector
The Simba TripleShield Tencel Cool Mattress Protector is a waterproof mattress protector made from breathable TENCEL fibres.
It's built with Simba's TripleShield technology, a barrier layer tested to the BS EN ISO 208 waterproofing standard.
This means your mattress is fully protectod from spills, sweat, and moisture.
TENCEL is naturally moisture-wicking and temperature-regulating, giving the surface a cool, smooth feel that's ultra-thin and virtually undetectable once fitted.
We'd recommend the Simba TripleShield Tencel Cool Mattress Protector to hot sleepers or anyone prone to night sweats who also wants full waterproof protection.
Reasons to buy
Genuinely waterproof, tested to BS EN ISO 208 |
|
Cooling, moisture-wicking TENCEL fabric |
|
Ultra-lightweight, low-profile fit |
Reasons to avoid
Higher price point than an entry-level waterproof protector |
Simba Quilted Performance Mattress Protector
- 200-thread count cotton
- Elasticated fitted sheet design
- Fits mattresses up to 40 cm deep
Tell me more about the Simba Quilted Performance Mattress Protector
The Simba Quilted Performance Mattress Protector is made of breathable 200-thread-count cotton and has a super-soft and luxurious feel.
It's infused with Bi-Ome technology, which actively prevents odours and eliminates the presence of microorganisms.
This makes the Simba Quilted Performance Mattress Protector a top antibacterial choice.
It will protect you against stains and bacteria, but you'll have to act fast if you spill your morning cup of coffee as water does seep through the protector - it's water-resistent but not waterproof!
We would not recommend this protector to children, people prone to bedwetting, or those who often eat or drink in bed.
Reasons to buy
Anti-bacterial protection |
|
Soft & quilted feel |
|
Available in UK & EU sizes |
|
1-year guarantee |
Reasons to avoid
Unfortunately, it isn't waterproof |
|
Quite expensive |
Which Simba mattress protector should you choose?
Simba's three protectors are built for three different priorities, so the right pick comes down to what matters most to you: Budget, temperature, or feel.
Here's how the three compare side by side:
| TripleShield Bamboo | TripleShield Tencel Cool | Quilted Performance | |
| Waterproof | Yes | Yes | No (water-resistant only) |
| Best for | Budget-conscious buyers wanting waterproofing | Hot sleepers and night sweats | Plush, cushioned feel |
| Feel | Soft, breathable bamboo | Ultra-lightweight, cool-touch | Thicker, quilted |
| Price from | £ | ££ | £££ |
If waterproofing is non-negotiable, say you've got kids, pets, or you just want peace of mind against spills, go for one of the two TripleShield protectors rather than the Quilted Performance.
Between those two, it comes down to price versus cooling. The Bamboo is the more affordable of the pair and has the softer feel, while the Tencel Cool costs more but is purpose-built for hot sleepers.
If waterproofing isn't a priority and you'd rather have the plushest, most cushioned surface, the Quilted Performance protector is still Simba's most comfortable option, though you're trading full waterproofing for a softer, more padded feel.
In short:
- Want the cheapest way to get real waterproofing? → TripleShield Bamboo
- Run hot at night and want waterproofing too? → TripleShield Tencel Cool
- Prioritise plush comfort over waterproofing? → Quilted Performance
Whichever you choose, all three fit mattresses up to 40 cm deep and are available across the full range of UK and EU sizes, so sizing won't be a deciding factor either way.

Waterproof vs. water-resistant: What's the difference?
This is worth its own section, since it directly affects which Simba protector suits you and it's a distinction a lot of shoppers miss.
- A waterproof protector has a barrier layer that stops liquid from passing through entirely. Spills, sweat, and accidents sit on the surface without reaching your mattress underneath, no matter how long they're left. Simba's two TripleShield protectors fall into this category, tested to the BS EN ISO 208 standard.
- A water-resistant protector, like Simba's Quilted Performance option, slows moisture down rather than blocking it completely. In our own testing, this protector held off moisture for around 1 - 2 minutes, enough to catch and wipe up a minor spill, but not enough to protect against something left to soak in or a heavier accident overnight.
If you're prone to night sweats, have young kids, pets, or just want maximum peace of mind, a genuinely waterproof mattress protector (Bamboo or Tencel Cool) is the safer choice.
If moisture isn't a major concern and you're prioritising comfort and feel, water-resistant protection (Quilted Performance) may be enough.
How do you wash a Simba mattress protector?
Washing needs differ slightly depending on which protector you own, because of the different fabrics and waterproof layers involved.
TripleShield Bamboo and TripleShield Tencel Cool (waterproof):
- Wash on a cool, gentle cycle (max 40°C) to protect the waterproof membrane
- Avoid fabric softener, which can clog the breathable layer and reduce waterproofing over time
- Air-dry or tumble-dry on low heat (high heat can damage waterproof coatings)
- Do not bleach or iron
Quilted Performance (water-resistant, cotton):
- Machine-wash on a 40°C cotton cycle with similar colours
- Use a non-bio detergent (avoid biological or enzyme-based options)
- Hang to air-dry or tumble-dry on low heat
- Do not bleach or iron
As with any mattress protector, we'd recommend washing every three months or so to keep dust mites and allergens at bay.
More frequent washed aren't usually necessary and can wear out the fabric faster.
What are the available Simba mattress protector sizes?
Conveniently, Simba's mattress protectors are available in a wide range of both UK and European sizes, and sizing is identical across all three.
- Simba single mattress protector UK: 90 x 190 cm (3' x 6'3")
- Simba small double mattress protector UK: 120 x 190 cm (4' x 6'3")
- Simba double mattress protector UK: 135 x 190 cm (4'6" x 6'3")
- Simba king bed mattress protector UK: 150 x 200 cm (5' x 6'6")
- Simba super king size mattress protector UK: 180 x 200 cm (6' x 6'6")
- Simba mattress protector EU single: 90 x 200 cm (3' x 6'6")
- Simba mattress protector EU double: 140 x 200 cm (4'7" x 6'6")
- Simba mattress protector EU queen: 160 x 200 cm (5'3" x 6'6")
The EU sizes are particularly convenient, especially if you have an old IKEA mattress or an EU-sized sofa bed.
How deep is the Simba mattress protector?
All three Simba mattress protectors have been designed to fit mattresses up to 40 cm (15.7 inches) deep.
This is great news if you have a very luxurious mattress, like the Simba Hybrid Luxe or Simba Hybrid Ultra, or if you’ve placed a thicker mattress topper, like the Simba topper, over your mattress.
Like a fitted sheet, each protector has elasticated bound edges so you can tuck it over your mattress very neatly.
A mattress protector is designed to fit over your mattress, mattress cover, and mattress topper but underneath your sheet.

Simba mattress protector delivery & trial conditions
Simba offers free next-working-day delivery for most UK postcodes on all three mattress protectors.
To qualify, simply place your order before 1pm; orders placed after 1pm will be delivered within two working days.
All three protectors arrive neatly folded in a cardboard box, minimising the use of plastic (the box usually comes wrapped in a shipping bag for protection).
We'd recommend giving it a wash before putting it on your bed.
All three protectors also come with a 1-year guarantee covering manufacturing defects.
There's no trial period but they're covered by Simba's standard 30-day return policy - if you decide a protector isn't quite right for you, you'll need to return it securely wrapped with the original packaging intact.
Should you buy a Simba mattress protector?
Simba's protector range now covers more ground than it used to.
- If you want genuine waterproof protection, both the TripleShield Bamboo and TripleShield Tencel Cool deliver it at a lower price point than the older Quilted Performance protector, and you no longer need to look outside Simba's range to get proper waterproofing.
- If comfort and a plush, cushioned feel matter more to you than waterproofing, the Quilted Performance protector is still worth considering, so long as you're comfortable with its 1 - 2 minute water-resistance window rather than full protection.
Overall, most sleepers, particularly anyone with kids, pets, or a habit of eating or drinking in bed, will get more practical value from one of the two waterproof TripleShield options.

Frequently asked questions
-
Does the Simba mattress protector come with a trial period?
No, none of Simba's mattress protectors come with a dedicated sleep trial.
As non-mattress items, they're covered by Simba's standard 30-day return policy instead, provided the product is returned securely wrapped with the original packaging intact.
-
Does the Simba mattress protector come with a guarantee?
Yes, all three Simba mattress protectors come with a 1-year guarantee covering manufacturing defects.
-
Are Simba mattress protectors waterproof?
It depends on which one you choose. The TripleShield Bamboo and TripleShield Tencel Cool protectors are both genuinely waterproof, tested to BS EN ISO 208. The Quilted Performance protector, however, is water-resistant rather than fully waterproof. In our testing, it let moisture through after 1- 2 minutes.
-
Can I use a Simba protector on any mattress brand?
Yes, Simba's mattress protectors can be used on most mattresses, not just Simba models.
As long as you choose the correct size, it should fit snugly and offer the same level of protection and comfort.
-
Does a Simba protector affect the feel of the mattress?
The TripleShield protectors are designed to be thin and virtually undetectable once fitted. The Quilted Performance protector has a lightly quilted design that adds a subtle layer of softness. It won't change the firmness of your mattress, but it may make the surface feel a little more cushioned.
-
Can I buy Simba mattress protector refurbished products?
If available, you can buy refurbished Simba mattress protectors from Simba Sleep directly.
-
Do the Simba mattress protectors stay in place overnight?
Yes, the fitted, elasticated skirt on all three protectors helps keep them securely in place, even if you move around during the night.
-
What's the difference between a Simba mattress cover and a Simba mattress protector?
There's a difference between the two:
- The Simba mattress cover is the actual cover on your mattress. It protects the inside of your mattress and, in many cases, is also removable and machine-washable.
- The Simba mattress protector is an additional fabric protector that you place on top of your mattress cover.
