About this product
Revive your mattress and enjoy fresher, more comfortable sleep with this topper that adds extra support where you need it most. It's deeply filled with anti-bacterial fibres that actively protect against bacteria and dust-mites, keeping your bed clean and healthy night after night. The copper infusion is naturally anti-bacterial, and it's designed to fit king size beds with elasticated corner straps that hold it firmly in place without shifting around. It's suitable for refreshing an older mattress or adding comfort to your current setup.
The cover is made from a soft-touch fabric that feels gentle against your skin and stays comfortable throughout the night. The elasticated straps slip over each corner quickly, so fitting is straightforward and hassle-free. It's machine washable at 40C and tumble dryer safe, which keeps maintenance simple for busy households. Pop it in the wash when it needs refreshing and it comes out clean and ready to use, delivering lasting support and freshness that makes a real difference to your sleep quality.

Customers Say
Mixed reviews on comfort and thickness; many find it thin (around 1cm) rather than advertised thickness. Positive notes on fit, copper antibacterial benefits, and improved sleep quality.

Topper is very thin
I bought this hoping for more comfort and support but unfortunately the product is very thin and hardly makes a difference

8mm not 8cm
A nice enough topper but it’s only about 1cm thick not 8cm. Nice quality and comfortable to lay on.

Very thin
Bought this recently and it’s very thin. I know it’s just a mattress topper but it’s so thin it makes no difference really.

Nice and cooling - solved a warm bed problem
My daughter was complaining that her bed was too warm, probably due to a memory foam topper, and it was affecting her sleep so I wanted to find something to put on top that would be cooling. I spent ages researching and this seemed to be the only option that I had any confidence might help. Thankfully it did and her sleep improved immediately! Would definitely recommend it to anyone feeling their mattress/topper is trapping heat and want to sleep at a cooler more comfortable temperature.

Makes bed very hot no health benefits noticed
Bought 2 of these can say there any thicker than my normal mattress protectors but thought I'd give them a try n the only thing that has changed is that they make the bed hot at night only hot 10.5 tog quilts on n window open all night n it's to hot in bed will definitely be taking them off once the warmer weather comes in

Hello Parchy,
I can advise the following for the Silentnight Wellbeing Copper Infused Mattress Topper- Single:
It's classed as supportive which would suggest that it's medium firm.
Thanks for using Q & A.
Hi Charlotte,
Having checked, it is recommended that an electric blanket should go on top of the topper not underneath.

Hello there. The Silentnight Wellbeing Copper Infused Mattress Topper is both washable and suitable for tumble drying so it should be ok to fold carefully and put away until needed again.
Thanks for using Q&A.
I put topper directly onto mattress followed by mattress protector then made up the bed as usual, sheet, duvet, pillows.
Hello Bridget,
The supplier has advised the following for the Silentnight Wellbeing Copper Infused Mattress Topper- Double:
"It is recommended to use a sheet with this item for hygiene reasons."

Hello Buster,
The supplier has advised the following for the Silentnight Wellbeing Copper Infused Mattress Topper-King:
This item can be used with a Silentnight branded electric blanket. It's not tested with 3rd party ones so we'd advise against it's use with a non-Silentnight blanket.
I hope this helps.

Hi Roadz,
The Silentnight Wellbeing Copper Infused Mattress Topper, King does not include a removeable cover.
Thank you for using Q&A.
Hi There
Depth measurements for mattresses and toppers are taken from the centre of the product. You can do this by using a long pole under and above the mattress or topper then measure between the two pole points.
I hope this helps
