Didn't know they sold mattresses - bought 2 Sealy mattresses - great deal and great service! I have paid so much more and had terrible service for other mattresses - so glad I discovered Appliances Online when referred by a friend!

I love this mattress! Thinking to change it for awhile and love this new one.
Hi very happy with my double medium bed I bought the base as well. Best things quick delivery free shipping. Had old bed well over twenty years if this last half that will be great value.
After doing some research and looking at many options we decided to go with the Sealy Advantage Cristal Medium King Mattress for so many reasons.The reviews were great, the mattress came in under budget and fit all of our needs.Very comfortable, well manufactured mattress, on the firmer side of medium but not uncomfortably so. I have a lot of back pain and now being pregnant, it has only increased and this has helped a lot.My fiancé has always preferred a more plush mattress but has said he’s sleeping a lot better now and doesn’t wake up aching anymore.So if you are on a budget, want a good quality mattress that ticks all the boxes from a reputable brand then this is the one!
The mattress is comfortable and I knew from Sealy it would be good quality,..love the fact that Appliances Online remove old mattress,...hassle free !!!!!
Simply amazing l have never had such a great nights sleep this is the most comfortable mattress ever!
Giving this a 4 star rating because while I found it very comfortable and I slept well on it. However, the person who will primarily be sleeping in it, says it is way too firm for him. It is meant to be plush and it feels like it’s way firmer. I do wonder if it’s a mis-labelled medium or firm mattress.
Great bed. I bought this for my teenager son. He loves it. Just the right size and right comfort. The materials are breathable. The support is just right. I also bought the matching bed base. They work seamlessly together. Very happy shopping experience!
