Appliances on line have the best service and products that I have ever purchases and I am in my 80's. The mattress is absolutely right for me as I have a back problem. Your support sales person, Christian was so helpful. The delivery men got here early - and were fantastic. I am very highly recomending you to anyone who will listen. Thankyou

So happy with my second mattress purchase from AO this month.The mattresses are amazingly comfortable and so restful.The service from AO was great from ease of ordering, to providing resolution when I had to change things and for delivery and removal of old mattress.

This mattress is definitely medium with a dash of plush. If you are looking for a soft medium this is probably not it but for me it is a great quality mattress and I know I'll sleep well for years to come.The delivery was super quick and the lovely delivery guys walked up to my apartment.

Needed a mattress. Nothing exciting to report on that front. It’s a mattress. It’s comfortable. We aren’t emotional about mattresses. However, effusive praise for the delivery team from Appliances Online. It arrived quickly, and at a time when the only adult home was my tiny, 50-kilo nanny. They delivered it up two flights of stairs, were courteous, and did not give my nanny any grief about putting it in the relevant room.
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!
It takes a little while for the matress to take on your shape . The deep cushion top helps with the comfort of my hips as l am a side sleeper . Thick fabric nice quality.
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 !!!!!
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!
