Package arrived fine. Mattress was easy to unpack and looks great. Sadly, it is really not comfortable. You can feel the springs through the top cover and it is super bouncy. Allot let supportive than expected. Slightly improved by adding a firm foam mattress topper, but still not great.

Sorry but the worst mattress I think I've ever bought.You can literally feel the springs digging into your back. I've had to buy a topper for it and tbh it still doesn't help much. I'll be buying a different mattress as soon as I can.

So good. Literally so comfy. I didn't think it was possible for a mattress to come in such a small package. I also didn't think it would expand very well and was a bit scared. But it literally just springs to life, it's very cool.

Super comfortable for the price - I've spent far more on mattresses before which I hated and I am genuinely very happy with my purchase. It conveniently comes in a box, easy to unpack and kind of fun to watch pop into life. I use this as my daily bed so I can confirm it's also great not just as a spare room mattress:

I love this mattress. It is firm but not hard. I have put a mattress topper on it, to have more height that suits my needs, and it is beautiful to lay on. I have had a spinal neck fusion and I have really bad Bursitis in both legs, left leg, from hip to toes, and right leg hip to knee, and arthritis in both, and was having bad sleep patterns and up and down all night, due to pain and waking up like a half opened pocket knife....No mattress will fix my issue's, but at least with this mattress I'm am having better sleep patterns. I'm not up as many times and I'm not as sore in the morning. I would recommend this mattress to everybody, and especially to people who have back, neck and hip issues.

Very happy with this mattress. I was surprised it came in a box! But it literally sprung into shape when unravelling it. Its comfortable and perfect for our Guest room. Delivery was prompt and great communication too! Thanks.

Delivery was super quick as usual it arrives one week before time frame given by supplier. We bought this one for Leo single bed as we where expected guests from Europe to arrive as far as they say it's comfortable I slept one night on it as well and it's comfortable little bit softer then mine mattress but it's really good value for money

Bought this mattress for the spare bed. My guests have no issue with it. They sleep well, pain free. I haven't rated it the five stars, as I've not actually slept on it. I've had several back operations though. Thanks heaps for an affordable comfy mattress

Comfortable, affordable and lightweight.
27 February 2023

Purchased for our small human. Delivery was fast and simple. Mattress itself is lightweight and very easy to manoeuvre to make up against a wall. The small human loves it and is comfy for a snuggle with Mum and Dad too. Recommend.

Reasonable for the price
21 February 2023

It’s okay for the price but don’t expect any good support. Using as a spare bed in guest room. It sinks down pretty quickly the moment you sit down. Mist softer than medium to be honest.
