The service was excellent, the attentiveness of the staff was appreciable and meaningful BUT the final choice was mine to make as was the regrettable decision: I ought to have selected FIRM, not Medium to Firm. I now tend to wake up at inconvenient times and have decided to exchange my current mattress for something more substantial . A second inconvenience is the turning of the mattress: at 84 years of age, it is something I'd prefer to avoid if at all humanly possible. How soon would I wish to do this? At the earliest opportunity. I continue to pour over your most recent selection and hesitate over prices involved. Could you offer any suggestions? My gratitude for your continuing excellence.

The off gassing was terrible. Couldn't sleep on it for weeks as the air was so toxic. Don't believe the marketing. Also the edges are a bit weak. Other than that it is comfortable to sleep on once it has off gassed.

Much too firm for us, very uncomfortable. Made my hips and shoulders ache. We are both medium build and have a slatted wooden bed base. May have been better with a sprung base or with a topper. Felt like it was dipping in the middle and springs started creaking after only 30 days. Exchanged for a medium under the 60 day scheme for a pocket sprung with latex top classed as medium.

This mattress is too hard for me. It would be perfect for a back sleeper but I’m a side sleeper and it’s causes me hip and shoulder pain. Buying a mattress topper has helped. It’s a sturdy mattress and well made. It’s easy to stand up from as its high and firm which is a plus point. I know I can swop it and mattress online are helpful and responsive.
