FAQs
Do I need to flip this mattress?
No, the King Arthur Mattress is designed as a single-sided mattress. Rotating it end-to-end is sufficient.
Is this mattress suitable for side sleepers?
Yes, the precision pressure relief technology is designed to cradle your body and maintain alignment, which is ideal for side sleepers.
Can I use this on an adjustable base?
Yes, the pocket spring and foam construction is designed to be flexible enough for standard adjustable base frames.
How do I keep the cover clean?
We recommend using a mattress protector to prevent spills and dust accumulation, as the cover is not removable.
Is the mattress heavy to move?
Due to the high-density materials, it is heavy. We recommend using two people if you need to reposition it.
Will I feel my partner moving?
No, the individually wrapped pocket springs are specifically engineered to minimize motion transfer across the surface.
Troubleshooting
The mattress feels firmer than expected after unpacking
High-density foams require a 'break-in' period of 2 to 4 weeks to adjust to your body heat and weight.
Edge support feels soft
Ensure the mattress is centered correctly on your bed frame to prevent overhanging which can compress the perimeter springs.
Odour upon unboxing
This is common for new foam products. Ensure the room is well-ventilated and the smell will dissipate within 48 hours.

Setup, Compatibility & Care
To ensure your Arthur Sleep mattress lasts, unpack it in the room where it will be used, as its high-density construction makes it heavy. Allow the mattress to expand for at least 4-6 hours (ideally 24) before placing heavy bedding on it. It is compatible with all standard bed bases, including platform beds and traditional slatted frames. Because this is a single-sided mattress, you do not need to flip it; however, we recommend rotating it 180 degrees every three months to ensure even wear. Clean the surface using only a vacuum attachment to remove dust and debris; avoid saturating the fabric with liquids, as this can damage the quilted cover and internal foam.
