Perfect quality mattress.
I’m very pleased with my new mattress. I have had sealy brand mattresses previously and was more than happy to purchase again. I’ve had the mattress for a week now and have had time to tell if I’m pleased with it. Which I am more than pleased to say has again come to fruition. I have had 2 spine surgeries and am very careful with what I sleep on at home, I generally don’t sleep too well due to chronic pain but I was not expecting any improvements in that direction, however even though I’m not sleeper for any longer i am noticing an improvement in the quality of sleep. I am very happy with my purchase.

Great Mattress
Great Mattress, good price, delivery was a shambles though, two delivery men couldn’t get it upstairs yet my son and daughter did it in 5 mins.

Great mattress for people with back issues
Was a bit wary about buying this without trying it out 1st (wasnt in stock in warehouse), however I decided to go for it after reading the reviews. So glad I did, after breaking/fracturing bones on my back, I can finally sleep in my own bed after 4 months! My husband thought it was a bit firm but has got used to it, anyway I bought it for my comfort, haha

Extremely satisfied.
Really happy with this mattress. Nice and firm and the “bubbles” feel amazing on the back. Very pleased. Would absolutely recommend especially if you like a firm mattress. Worth every penny.
Baz from Melton Mowbray –
Quality mattress
Impressed with the quality of the mattress so far. Was initially concerned as there are cheaper mattresses available but it’s easy to see why this one was worth the price.
