Great service. Great mattress. Even took the old one away. Thank you
Still investigating ideal adjustments for me but the mechanism is easy to use and has already helped relieve sacroiliac pain as a result of raising the foot of the bed.
Purchased this Sealy mattress on 12 April 22 and was delivered 13 April 22. Absolutely fantastic service from AOL. The Carriers carefully unpacked and placed the mattress on the bed and removed the old mattress. Exceptional & Professional Customer Service.The Mattress is a great design, firm but very comfortable providing great body support and a relaxed and restful sleep. Great price absolutely value for money, it is always a pleasure dealing with Appliances on Line who provide a great shopping experience.
This Sealy Posturepedic Summer Flex firm Queen Mattress was very comfortable to sleep on from day one. It is firm and we didn't have any trouble adjusting to it.
A wonderful mattress, I actually fell asleep within minutes of trying it out. Perfect comfort, firm but still softly comfortable. Really happy.
Purchased this mattress in August. It is extremely comfortable and has alleviated my back and hip pain from our old mattress. Firm as described with a great comfort factor. Priced appropriately and the delivery was quick and easy with great communication regarding delivery time on the day.
Our new mattress and base are great. We were told that it may take time to get used to but we loved it from the first night.
