Koala Mattress Layers

Sleeping Duck

The Sleeping Duck Mach II is available in three options, medium, firm and custom.

  • Medium firmness: Rating of 5.5/10
  • Firm firmness: Rating 7/10
  • 5 zones: Custom to you

With regards to comfort, this really depends on which firmness setting you’d prefer.

You also have the option to adjust the firmness across 5 different sections of the mattress from head to toe.

This would be useful if you require, say, more support on your hips but less for your head.

Koala Mattress

On the other hand, the Koala mattress has one firmness rating being 6.5/10.

Some customers have complained though that after 6-12 months, they notice the mattress starts to sag, not making it the most durable option for some.

  1. Koala mattress arrived on same of ordering which was amazing service.. On unpacking it was incredible there was a cuddly koala inside.. so cute and thank you..
    I’ve just tried the koala loved it..
    Its like sleeping on a cloud feels light under your body plus very cool in temperature..Great support without being harsh or feeling as though you’re being wrapped around it or sinking into it… I just felt I was on top of the mattress such an airy feel to it.. Incredible feeling and eased my aches and pains…
    I have a bad back.. neck pain which would result in disturbed sleep..
    This mattress was a dream to me it was honestly the best matrass I’d ever had or slept on.. But unfortunately I was very reluctant to return it due to irritated eyes???
    There must had been something in the material I was allergic to ( I DO NOT HAVE ALLEGIES)
    So over the next 4 weeks I alterned sleep from the old mattress and koala… when I went back to the old mattress my eyes had no problems, the next evening I’d try the koala but the following morning my eyes were swollen irritable and very weepy… It was with deep regret I had to call koala to pick up the mattress.
    There were no troubles in returning.. Was picked up with no problems.. the full refund of the money deposited into my bank account as promised.. no charge for delivery or pick up and you were even alloeed to keep the cuddly toy koala with his blue waistcoat..
    If I did not have thevallergic reaction to the mattress I would never have returned it.. It was perfect for me… I aired it as instructed and followed all the recommendations… I used a mattress protector and that was washed every morning after I slept on the mattress the night before.. I was hoping whatever irritated my eyes, would, over a period of time, improve and be irradiated but on this occasion it wasn’t to be…
    I would have no problems
    recommending the koala mattress, even though it did irritate my eyes..the sophisticated technology that gives you a wonderful mattress that in turn gives you a restful night sleep is truly amazing… 🦉🛌💤🌛🌟
