I love my mattress. Just the right firmness for us - not too hard but not too soft. Delivery on time and although far from the cheapest mattress, it was worth every penny and so pleased we went with king and not double

Wasn't sure about the type of mattress we needed / wanted and after being advised and guided by the staff, I opted for the ultra arden. Can safely say it's the best mattress weve ever had. Super comfortable and had great night's sleep since delivery.

The mattress looked like it would be a cosy dream. It was anything but. It was so hard for medium firm. You could feel the bed frame through it. For over £2000 it was a total let down. The 60 day trial is a lie. It was lucky I called early to ask if I could send it back as it gave me a trapped nerve in my shoulder I am still struggling with 6 weeks later. You actually only have 28 days to send it back and you have to pay from your own pocket to return it. £180 to return it. They really should highlight that fact when you buy I know it is in the small print but come on. Lastly we were going to exchange with Mattressonline for another around the £1,200 mark ( there are not many in the £2000 bracket) and after how bad it was we wanted to go back to a brand we knew. They said they could but we would need to take £800 in credit. We only have one bedroom/one bed. So no need for £800 credit as we didn't need anything else. It was all a total hassle. On recommendation from friends we have bought an Ikea VÅGSTRANDA pocket sprung mattress for £515 and I have to say it is the comfiest mattress I have ever slept on. Much like a hotel vibe.
