Finding the perfect fit for your mattress
Our Oxygen Room grounding fitted sheets are available in four popular UK bed sizes, with two depth options to suit standard and deeper mattresses.
Made from soft, cotton-rich fabric woven with conductive silver fibres, they're designed to fit comfortably over your mattress, just like a traditional fitted sheet.
Our available sizes
| Bed Size | Mattress Width × Length | Standard Depth | Deep Fit |
|---|---|---|---|
| Single | 90 × 190cm | 33cm | 40cm |
| Double | 135 × 190cm | 33cm | 40cm |
| King | 150 × 200cm | 33cm | 40cm |
| Super King | 180 × 200cm | 33cm | 40cm |
What if your mattress is slightly different in size?
Not every mattress measures exactly the same. Some are a few centimetres wider, longer or shorter than standard UK sizes.
Like traditional fitted sheets, our grounding sheets may accommodate small differences in mattress measurements.
As a general guide, a variation of approximately 2–3cm either way may still provide a comfortable fit, depending on the mattress depth, elasticated corners and fabric construction.
For example, a mattress measuring 92 × 190cm may fit our Single sheet, while one measuring 137 × 190cm may fit our Double.
These are examples rather than guaranteed fits, as the manufacturer's exact stretch tolerance has not yet been confirmed.
Which depth should I choose?
33cm Standard Fit: Suitable for many standard mattresses, provided the sheet has enough fabric to sit securely beneath the corners.
40cm Deep Fit: Better suited to thicker mattresses or mattresses with toppers.
Measure the full depth of your mattress, including any topper, before choosing.
Not sure which size to order?
Simply measure your mattress's width, length and depth in centimetres and contact Oxygen Room.
We'll help you choose the closest available size so you can enjoy a comfortable fit without unnecessarily stretching the conductive silver-fibre fabric.
