Which Comfort Level Is Right For You?

Whether you’re a side, back or stomach sleeper, lean towards a softer mattress, or a firmer one, we've got your back. Our Athena mattress combines the pressure-relieving buoyancy and lasting resiliency of natural latex to deliver the comfort you want and the support you need.

  • Side Sleeper

    Side sleepers generally prefer a softer top comfort layer that allows your shoulders and hips to sink into the bed. This helps alleviate pressure points and promotes good spinal alignment. A plush soft to medium-soft comfort setup should be ideal for side sleepers.

  • Back Sleeper

    The mattress should be firm enough to protect the back when sleeping on the back. Consider medium-soft to firm comfort setup, depending on your physique and preferences.

  • Stomach Sleeper

    Stomach sleepers need a firm mattress. Otherwise the torso will be sinking too much into the mattress causing the spine to be misaligned and develop back pain issues. Choose a medium-firm or firm comfort setup.

  • Combination

    If you tend to move positions while sleeping, a medium to medium-firm option is the best bet for consistent support that caters to the different sleeping positions.

Advantages of Sleeping on a Spring-less Mattress

Compared to traditional spring mattresses, our all-natural latex mattresses offer additional comfort and support delivered through the combination of the different layers of latex.

Our mattresses are also more durable as metal springs could give way after only several years of use. Lastly, our metal-free mattresses remove potential creaking noises typical of spring mattresses, offering a quieter sleeping environment.

    I’d give a 6/5 if I could!

    First up it’s half the price of a Heveya, and the layers are fully customizable so you (definitely) get a bigger bang for your buck. I’ve been sleeping on this mattress for >1month and have nothing but amazing reviews about it - sleep so well every night! Lastly the teams service is very authentic, friendly, patient and customer centric, none of that corporate nonsense you get from other companies. I highly recommend!

Frequently Asked Questions

What are the standard configurations for each comfort level?

The latex comes in 4 firmness levels: 1) super-soft; 2) soft; 3) medium and 4) firm. Our standard recipe are:

Plush-soft: super-soft over soft over medium

Medium-soft: soft over medium over firm

Balanced medium: medium over medium over firm

Medium-firm: medium over firm over firm

Firm: Firm over firm over firm latex

How long does the assembly of the Athena take?

About 10-15 minutes. We recommend having two people for assembly, but this is not strictly necessary. For assembly instructions watch our assembly video above.

Is latex mattress hot to sleep on?

Natural latex mattresses are naturally breathable and promote good air circulation, making them less prone to trapping heat compared to many other mattress materials. While individual experiences may vary, many find latex mattresses to offer a cooler sleep surface than foam mattresses.

What is the ideal firmness for me?

The role of a good mattress is to ensure that you sleep comfortably and get good spinal support during sleep. The ideal mattress for you will depend on many factors, including your physique, height and weight, and sleeping posture.

In general, side sleepers will like a softer mattress since their shoulders and hips push further down into the mattress. Stomach sleepers will sleep better with a firmer mattress while back sleepers will generally require a medium to medium-firm mattress.

The benefit of a Good Knight mattress is that you don't need to stress about it. Start with your best guess. Then change a layer for free without the need to return and buy a whole new mattress.

Do you customise mattress sizes?

Yes, in fact, we specialise in custom mattress solutions for our customers. We can customize the size of your Athena Mattress for an additional fee. All customised orders have a usual lead time of 2-4 weeks.

What's included with my Athena mattress?

Your Athena mattress comes with three latex foam layers encased in a zippered mattress cover.

What type of frame can the Athena be used on?

You can use your Good Knight mattress on any firm, stable base in good condition. You may also use a slatted base but ensure that the gaps between the slats are between 5 and 7.5 cm.
