The Milford Mattress is designed with a 30cm, 5-zoned pocket spring system. A pocket spring system is created coil systems that are individually wrapped and sewn into the mattress below a comfort layer. It is uniquely designed, allowing for weight distribution variances throughout the mattress on areas that need greater (think head and hips) or less (think feet) support.
The Milford Mattress is finished with synthetic latex foam for ultimate comfort, light feeling bounce and airflow. This creates ultimate comfort with a lesser level of ‘hug’ than memory foam.
Designed seamlessly with air pockets integrated into layers of the foam, ensuring ultimate airflow throughout the top layer.
A textured layer of memory foam with a ridged design of peaks and valleys. This light layer allows for airflow and helps to align the spine and eliminate pressure for a resultful sleep. This in conjunction with our 5-Zone Pocket Spring system provides true ergonomic support while you sleep.
The Milford Mattress arrives at your door conveniently in a Flatpack Co. box. Our innovative packaging is significantly smaller than traditional mattresses, merging vacuum packing and a rolled design. This allows for easy movement upstairs, round tricky corners or through smaller door frames.

Exactly as described and fantastic customer service
Great to hear Britta! I'll pass your kind words on to the whole team, so glad your Milford arrived exactly as described. - Cam
This mattress replaces one we slept on every night for 16 years. What a contrast! While our old mattress was very soft and offered little support, this Flatpack Co. mattress is perfectly firm and supports our bodies in all the right places. The first night I slept on my back (which I definitely couldn't do on the old mattress) and I could literally feel the difference with my lower spine/hips elevated and aligned. With the old mattress I would also get frequent, heavy night sweats but I haven't sweated once since we got the Milford mattress–rejoice! Although it has only been a few weeks the upgrade is evident and we're very happy with our purchase. This mattress provides immense value for money, even if they aren't on sale. But we got this during the Labour Day sale, so if they come back on sale for Black Friday or Christmas...GET IT!
Thanks so much Benjamin! Really appreciate you taking the time to write such a generous review and recommending us to other shoppers, and the Milford looks great in your room! - Cam
Just the right firmness for me. I also hadn’t slept in a bed for 3 months before sleeping on this mattress. I was transported to sleepy cloudland.
One week in and it’s still excellent.
Stoked week one is still excellent, thanks so much for the review and enjoy 'sleepy cloudland' with your Milford + Raglan! - Cam
Seems very good quality and a firm mattress which is what my daughter needed as she is a tummy sleeper sometimes and her old mattress had a dip in the middle of it. Having a disability is important that she gets a good night sleep. Purchased the wooden base as well and this seems very good to for her needs.
So glad your daughter is getting the good night's sleep she needs, Lynda, especially after that old dipped mattress. Wishing her many more comfy nights on her new Milford. - Cam
I love my new Milford mattress very high-quality no now I can sleep well without cousin any pain to my side or my back
Happy to hear you're finally sleeping without that side and back pain Jordy! So glad your new Milford is treating you well, enjoy. - Cam
