  • Our Shin Ju X air-gel memory foam mattresses feature an all foam mattress topped with a super cool Air-Gel Memory Foam layer. Unlike normal gel memory foam, where gel is added into "normal" memory foam, we add gel into "air" memory foam which makes our mattresses much cooler and softer. The sides of the mattresses also features a "breathable" side fabric which is more breathable than normal mattress fabrics, providing better dispersion of body heat while sleeping.

    First Layer 2.5cm Air-Gel Memory Foam
    Second Layer 5cm Gel Soft Regular Foam

  • The Shin Ju Story

    The Shin Ju (真珠) mattress was designed to change the way the mattress industry operates. For too long the mattress industry has taken advantage of the ignorant masses to enjoy massive profits. Mark-ups ranged from 3 to 10 times of factory costs. We want to change all this.

    Change the mattress industry by Shin Ju II Latex Foam Pocketed Spring Mattress

    1. The original Shin Ju (真珠) mattress was designed specifically for SEX. The literal meaning is "real pearl". Shin Ju is used colloquially as an erotic term in the Japanese language. 

    2. Four Main Mattresses - Almost all major mattress brands have dozens of models. By having only four we can bring manufacturing and marketing costs down. We focus our resources on developing the best four mattresses in the world in the under $2,000/- category.

    3. By having the price lowered to from just $299 for a luxury specified model we can sell in volume. We continue to use luxury materials such as latex foam, double knitted fabrics, Supakuru high tech wicking technology and double tempered carbon springs. 200,000 mattresses are sold in Asia per month. To lower costs, we have done away with fancy labels, trimmings, and non-functional items.

    5. Our factory direct to consumer model cuts out the middlemen and further reduces costs. Traditional mattress brands use importers, stockists, wholesalers, dealers and licensing agents. These layers just increase the mark-ups.

    E-commerce Shin Ju II Latex Foam Pocketed Spring Mattress

    6. We have also have done away with the chain store concept. We focus on e-commerce and just one showroom. No huge rentals, no army of salesmen salaries and commissions and lower operational costs. 

    7. We are so confident of our product we provide a six month warranty up to the full purchase value of the mattress. Our competitors have bullshit 20 year limited warranties with a million conditions that literally render their warranty useless. If the mattress is not suitable just return the mattress to our service centre in good condition in the original plastic bag. No questions asked.

    8. Our Shin Ju 2+ mattress is specially developed to fit 97.3% of the world's population. Its euro-top provides support for all positions of sleep. Suitable for people with weights from 40 to 90kg. The sleeping surface uses our advance super cool fabric (Lycocell® 3) which is specially formulated for hotter and more humid climates.

    9. Our Shin Ju Air 1 is designed specifically for LONGER SLEEP; an upgrade from our entry-level Shin Ju 2+ and also an introduction to our more premium Shin Ju Air-Series. 

    10. Our Shin Ju Air 2 mattress is specially developed with a focus on SEX. It is firmer and has extra bounce for better-timed movement. Its matrix integrated spring system is specially developed for continuous impact, roll and both vertical and horizontal sway. This mattress is additional fitted with an M-Guard edge support. This prevents the mattress edge from sinking in certain sex positions. This M-Guard however prevents this mattress from being rolled and compressed. The sleeping surface uses our original super cool fabric (Lycocell® 2) which is specially formulated for hotter and more humid climates.

    11. Our Shin Ju Air 3 mattress is specially developed with focus on BOTH SEX and SLEEP. It has an extra euro-top for better side-sleep support. More than 60% of the population are side-sleepers.
