Love this mattress! All the mattresses in my house are serta brand. I got this one firm with the plush top and it is so comfortable! Very happy with this purchase. I'm pregnant and have back issues during and just normal so I am picky about mattresses. I love sleeping on this bed, I have no back or shoulder pain when I wake up. Highly recommend!

Nice Mattress but the worst experience

Never buying from Serta a 10/24/2023

Bad overall experience. Was forced to re schedule 15 times due to extremely poor communication between Serta and delivery group. Also, the Serta customer experience team would average a week to respond to concerns or questions.

I bought this bed for our guest room. As soon as I get new sheets and a mattress cover, I'll try sleeping on it for a while. It feels very comfortable when I lay down on it. I also got the adjustable base. I really like that and want one for my bed!

This one is a keeper

CCK1 9/19/2023

My husband and I had been shopping for a new matress to replace our 22 year old mattress for several months. Truthfully, our old mattress was still quite comfortable despite its age but I thought it was time to replace it. Prior to purchashing our Serta mattress, we had purchased 3 other mattresses all of which were returned for various reasons, They were either too firm, lacked edge support, sagged after just one week of use, or had excessive motion transfer. We had to keep bringing our old mattress back into the bedroom. Then we purchased this Serta plush pillow top mattress. Not only did it cost significanttly less than the others, it had all the qualities the others lacked. It had the perfect amount of firmness/plushness, strong edge support and virtually no motion transfer. Our only issue (more my husband's than mine) was that the mattress was advertised as measuring 79.5 inches in length and we measured it at 79 but we have learnt that 79 inches is the length of most mattresses, including our old one which had been our gold standard. All in all, we are very happy with our purchase.

Soft mattress

Deidre E 8/20/2023

I want a mattress that has a medium level of firmness. This mattress is definitely soft, and not what I want. I slept on a couple hotel beds recently and noticed a significant difference. They are "medium" firmness. So, this is a disappointing purchase.

Best Mattress Ever!!!

Btater 5/10/2023

I upgraded from a mattress in a box to the Serta Plush. I've had it about 3 weeks now. This was such an upgrade compared to the mattress I had been using! It's so soft and literally feels like you're sleeping on clouds. I suffer from severe insomnia and neck and back pain. This mattress has really made a difference! Hoping it lasts for years to come! Would highly recommend this mattress!!!

KristenO 5/9/2023

We bought this mattress and loved it at first, but after about a year there were already serious indents. My husband especially was so uncomfortable that we ended up buying a new mattress. We are bummed that we spent this money only to have to reinvest in a new one so soon.

Warranty Registration Runaround

Joe153 5/7/2023

I got this mattress yesterday and it was comfortable for the first night. Hopefully this will continue. My problem is with trying to register it for the warranty as they suggest in two different places in their literature. I have tried both sites that they state and neither one lets me register the product as they suggested. Instead, I have gone around in circles for an hour to no avail. Not a great way to begin an association with a company. It is Sunday and their offices are closed.

Love this mattress!

RazzyBerryB 5/4/2023

I have had two separate back injuries (one mid-back, one lower back) that have left me with arthritis, so finding a quality mattress for a good price can be a challenge (I generally like my mattress on the form side). Add to that the fact that my husband loves soft beds and especially memory foam, I assumed we would never have a bed we both really loved. This mattress gave us both everything we were looking for. As a hybrid, it gives him the soft feeling he wants yet still has the coils to support my back. Neither of us wake up in pain anymore, and we are sleeping very well. I can't give this mattress more praise-good sleep has given us both a better quality of life, and if that wasn't enough, the cost couldn't be beat.

Les123 3/24/2022

I will be returning this mattress. This is the firmest bed I've owned. There's nothing plush about it. When u lay on it, it's like laying on a board. I can feel my hips on it which I was told this was a side sleeper mattress.

I find that I'm not tossing and turning trying to get comfortable all night. This is such a great quality and comfortable mattress!

I have back issues and this mattress is perfect for me , its not to soft and not to hard and for me, I sleep so good on it. I love the way the pillow pocket design and made with gel and foam and coil keeps it soft but at the same time firm. it also keeps me cooler at night so i sleep better. the mattress is not heavy and fit right onto my box spring and bed frame with no issues. I am super pleased with the Azure Bay mattress
