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.

Best mattress I have ever owned, love cutting the packaging and watching it instantly inflate. Left for a few hours and slept on that night, instructions say best to leave for 24 hours but it was fine same night.
Great mattress - should use a mattress protector straight away as notice some loose fibres from the first few days without sheets
Thanks Nicholas! Glad the Milford & Piha are both proving comfy. Hopefully you've sorted a mattress protector (and found some sheets too!!). All the best from us :) -Cam
Delivery was easy and the mattress was super easy to unpack. We are sleeping well on the new mattress. I would definitely buy one again. Many thanks 😊
Amazing Bev. Can't beat that for a review! Thanks :) -Cam
Very happy with my purchase
Thanks Bill. Glad to hear it's all worked well, and delivery out to the West Coast went smoothly! -Cam
Our purchase arrived promptly despite a phone number hickup. Amazing how this "mattrass in a box " works. A bit scary when it comes alive when the restrictions are cut away!
A mattress is a very personal item. We have only just started to test it out and obviously will need a bit of getting used to. But so far, we're very pleased with this product, especially because it's kiwi based, innovative, and considerate of the environment.
Thanks Michiel! So glad we were able to get the phone number sorted so you received the SMS to confirm your delivery time. Glad you're pleased so far with your new Milford :) -Cam
What a difference this matress has made, absolutely life changing. The milord matress is so comfortable, we haven't slept so well in years. It fits so well into the piha base , just perfect. I cannot believe how amazing it felt after sleeping on this matress. No back pain, no neck pain, and I actually slept through the night without waking. We absolutely recommend the matress, 10/10.. so glad I found your website flat pack team. Thank you so much. Absolute value for money.
How awesome Tania! Sounds like your Milford + Piha combo is working wonders for you! Stoked we could help you out and thanks for the very kind words, we really appreciate it! I will be passing this lovely review on to the whole team. Thanks, Cam
This mattress is perfection, not too soft, not too firm, just the perfect amount of everything.
Wow thanks so much Genevieve!! Such an awesome review to receive! I'm so glad you're finding the Milford to be 'perfection'! Enjoy - Cam
When I saw how thin the mattress was before I let the air in. I thought, there's no way that mattress will be supportive enough. But we love it.
So awesome to hear that, Mathew! Stoked that your Milford has pleasantly surprised you! + glad you’re loving it. Enjoy - Cam
