    Comfort with No Springs Attached

    Enjoy perfect bounce without metal springs. The comfort and support of the Marina mattress is delivered by the purest natural latex rubber foam and nothing else. Experience superior comfort and support for your body. No springs attached!

    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 Marina 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 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 a medium 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.

      Good Knight gave a solution.

      Recently bought Marina mattress from Good Knight. I experienced a luxurious sleep with Natural Latex and feel better with my back-pain too. In search for a better night of sleep, Good Knight gave a solution. Thank you very much Good Knight team for customizing the mattress which suits me and also your friendly support. I recommend this mattress.

      The mattress is so comfy!

      EK and Serene were very patient and answered all my questions. The mattress is so comfy and the best selling point for me is that it is priced competitively in the market, considering that its 100% latex. Latex is hypoallergenic, so it's quite resistant to mold/mildew/dust mites etc! It also doesn't have toxic compounds (VOC etc)!

      Thank GK and team for making my move in to new place less of a hassle n worry!

      My mum who suffers from joint pains, says she feels well rested and comfy while my dad who usually complains alot abt mattresses, sleeps earlier now and with no complaints, which i am sure is because of the mattress! I think they have never experienced such a good mattress.

      Thank GK and team for making my move in to new place less of a hassle n worry!

    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:

    Medium-soft: soft over medium

    Balanced medium: medium over medium

    Medium-firm: medium over firm

    Firm: firm over firm latex

    How long does the assembly of the Marina take?

    About 10-15 minutes. We recommend having two people for assembly, but this is not strictly necessary.

    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 Marina Mattress for an additional fee. All customised orders have a usual lead time of 2-4 weeks.

    What's included with my Marina mattress?

    Your Marina mattress comes with two latex foam layers encased in a zippered mattress cover.

    What type of frame can the Marina 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.
