Here is more some more information about our mattress topper

 

Why go for a 10cm (4inch) thick mattress topper?

The Supreme Slumber mattress topper features a 10cm (4-inch) thick gusset, which offers several key advantages. This extra thickness provides enhanced support, especially for side sleepers, by promoting better spinal alignment and relieving pressure points. The thick gusset also ensures even distribution of the topper’s 1000gsm filling, preventing it from shifting or clumping over time. Additionally, the increased height allows for improved airflow, helping to regulate temperature and keep you cool throughout the night. This design makes the topper ideal for those seeking both comfort and longevity.

Fun website to explore, brings joy to the heart. Delivered within 5 working days. Loved the packaging and felt the quality as I opened up my topper. Used it in my camper trailer to change the standard mattress to a hotel quality mattress. Slept like a princess last night - it made such a great difference. Worth every cent. Will highly recommended this topper.

I’ve been wanting to upgrade our mattress for a while and came across this mattress topper - it’s truly given our mattress a whole new life! It’s super plush and cosy, so easy to put on our king bed and feels amazing to sleep on. My husband has had back pain/injuries for many years and has also loved the topper. It’s supportive but gives a snug feeling at the same time. Would definitely recommend to anyone wanting to improve their sleep without the price tag of a whole new mattress.

The first night I used it, I noticed how well it cradled my body and eased the pressure on my back and shoulders. I often wake up with stiffness after long shifts, but this topper made me feel soo refreshed in the morning. It provides just the right amount of support while still feeling soft and cozy. Great value for the money - Highly Recommended!

Great mattress topper! Ordering easy and arrived promptly. I could track with Aust Post. Packaging great and professionally presented product. Exceeded expectations on the bed as it was very soft and luxe in feel with a deep skirt to stay on the bed. Beaut nights sleep and loved the snuggly feel. Very comfortable bed! This would be an excellent topper in our caravan too and reasonable pricing. Thanks
