Custom-made mattresses

Standard sizes don’t always fit the room’s dimensions or individual needs. That’s why we offer custom-made mattress solutions, ensuring personalized comfort without compromising the design of your bed or bed frame.

How thick should a mattress be?

Height directly affects comfort and durability.

• Between 16 and 20 cm—not recommended for adults.
• 24–30 cm – greater comfort, multiple layers of material, and better support.

We recommend mattresses that are at least 20 cm thick for adults to ensure proper spinal alignment.

 

Which is better for your back: a spring mattress or a foam mattress?

This is one of the most common questions. The answer depends on the user's profile:

Pocket-spring mattress:

• Firm support, excellent breathability, and freedom of movement, providing targeted support and reducing motion transfer.
• Ideal for couples and users looking for firmness combined with comfort.

Memory foam mattress:

• It conforms to the body, reduces pressure points, and helps align the spine.
• Recommended for people who suffer from lower back or neck pain.
