Great mattress - firm but yielding, cosy but cool. Not too much rock 'n roll, contributes to excellent technicolour dreams. The cats and wife also approve.
Oh my gosh, this is such a comfortable mattress and I was long overdue for an upgrade.. valve for money. Appliances online delivery service is exceptional.. thank you
The mattress is just as described. It suits us, and the service from Appliances on Line was exceptional.
Every thing I wanted for sweet dreams, so comfortable and brilliant with the adjustable base.As always with Appliances Online ,swift delivery and removal of the old bed...next day delivery and free. Excellent service
So plush and comfortable, never thought I would sleep so well
This mattress is so comfortable, has also helped with some minor back issues being caused from my old mattress. Am now having a great night's sleep. The delivery was seemless, the guys took the old mattress away and placed the new one on the bed. They were very courteous and efficient. Very happy!
