Product Information

Full details

The King Arthur Mattress is designed for individuals seeking luxurious comfort and exceptional, medium-firm support for restful sleep. Its key benefit is the advanced pressure relief and motion isolation provided by its hybrid construction. A potential caveat for some users might be its medium-firm feel, which may not suit those preferring a very soft or very firm mattress.

FAQs

What is the firmness level of the King Arthur Mattress?

The King Arthur Mattress is rated as medium-firm, making it suitable for a wide range of sleepers who prefer balanced support and comfort.

Do I need to flip this mattress?

No, the King Arthur Mattress is single-sided and designed to be rotated head-to-toe only, not flipped.

How long does it take for the mattress to fully expand?

After unpacking, it typically takes between 24 to 72 hours for the mattress to fully expand and reach its intended shape and comfort level.

Is this mattress suitable for hot sleepers?

The mattress features a breathable, quilted cover designed to promote airflow and help regulate temperature, making it a good option for many sleepers, though individual experiences may vary.

What is the warranty period for the King Arthur Mattress?

The King Arthur Mattress comes with a 1-year guarantee.

Can I use this mattress on a slatted bed frame?

Yes, it is compatible with slatted bed frames, provided the slats are no more than 7cm apart to ensure adequate support.

What are the dimensions of the European Double size?

The European Double size measures H:34 x W:135 x D:200 cm.

Troubleshooting

Mattress not fully expanding after unpacking

Ensure the mattress is placed in a well-ventilated room and allow up to 72 hours for full expansion. Check that all packaging is completely removed from the mattress.

Noticeable odor upon unpacking

This is common with newly packaged mattresses and is typically a harmless off-gassing smell. Allow the mattress to ventilate in a well-aired room for several days until the odor dissipates.

Uneven support or sagging after a few months

Rotate the mattress head-to-toe as recommended. If the issue persists, contact customer support regarding the warranty, as this may indicate a manufacturing defect.

Partner disturbance is still noticeable

While the mattress offers good motion isolation, individual sensitivity varies. Ensure your bed frame provides a stable, flat surface, as a faulty frame can sometimes transfer more movement.

Pros and Cons

Pros

  • Award-winning for support and durability (Which? Best Buy 2025, Good Housekeeping Approved 2024)
  • Excellent motion isolation due to pocket springs, ideal for couples
  • Provides targeted pressure relief for common aches and pains
  • Suitable for a variety of sleeping positions (back, side, stomach)
  • High-quality materials and construction for long-lasting comfort
  • Breathable cover enhances sleep temperature regulation

Cons

  • Medium-firm feel may not suit those preferring very soft or very firm mattresses
  • Requires occasional rotation, not flipping, which is still a maintenance task
  • Arrives vacuum-packed and rolled, requiring time to fully expand
  • Specific dimensions (European Double) may not fit all standard bed frames
  • 1-year guarantee may be shorter than some competitors

Setup, Compatibility & Care

Setup:

  1. Carefully unpack the mattress. The King Arthur Mattress arrives vacuum-packed and rolled.
  2. Place the rolled mattress on your bed frame.
  3. Slowly unroll the mattress.
  4. Remove all packaging material.
  5. Allow the mattress to expand fully for at least 24-72 hours before use. It will gradually regain its intended shape and thickness.

Compatibility:

The King Arthur Mattress is compatible with most standard bed bases, including divan bases, slatted frames (ensure slats are no more than 7cm apart), and platform beds. Ensure your bed frame provides adequate support to maintain the mattress's integrity.

Care:

  • Rotation: This is a single-sided mattress, meaning it does not require flipping. However, it is recommended to rotate the mattress head-to-toe occasionally (every 3-6 months) to ensure even wear.
  • Cleaning: For minor stains, use a soft cloth lightly dampened with water and mild soap. Blot the area gently and allow it to air dry completely. Avoid soaking the mattress.
  • Protection: Using a mattress protector is highly recommended to safeguard against spills, stains, and allergens, and to prolong the life of your mattress.
