Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Mattresses can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new bedding should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.

Everything you need

Mishulii 3/14/2025

This is my first experience with Sealy mattress. I am married and have completely opposite needs from a mattress than my husband. Finding a mattress that satisfies both of us is almost a miracle. I need a more firm mattress but soft enough to have my spine leveled and not waking up with a hip pain (I sleep on my side). My husband needs softer mattress because he has lower back pain. I sleep hot so I need the mattress to regulate temperature so I don't get too sweaty but also not too cold. I usually don't like 100% memory foam mattresses because they get too soft (even eventually) and the spring mattresses are usually pretty stiff. This hybrid is perfect medium in my opinion. Thanks to the springs I am hoping it will actually lasts this way. After a month or so we both agreed we have been waking up with no pain and actually rested. I didn't have to cover and uncover a million times throughout the night. So far we are really happy with this mattress and let's hope it will last for a couple years. I think this mattress would be also fantastic into guestrooms since I feel like it would be comfortable for anyone with different needs.

So happy with this mattress!!!!

Caroline 3/10/2025

Sealy kindly gave me this Posturepedic Pro Hybrid Medium, Queen for free so that I could review it. Full disclosure I wasn't expecting to like it this much as I do. We put this in our guest bedroom and have slept on it multiple times because it's so comfy. (we have a king in our main bedroom) IMO it has the perfect amount of firmness-not too soft, not too firm-right in that ideal middle ground. Just be aware that it takes about 2-3 weeks to really settle in, but once it does, it's AMAZING. Really conforms to your body. Pleasantly surprised how much I like the gel memory foam. It provides a nice cooling effect and I tend to sleep hot. Pairing it with a warmer down comforter and quilt is honestly perfection. We are considering getting one for our main bedroom now in King size. Highly recommend!! Good luck on your mattress purchase and hope this helps :)

The best mattress I have ever slept on !!!

Heatherr 3/9/2025

I recently switched my mattress to the Sealy Posturepedic Dupont Hybrid II , it has been the best sleep of my life. The mattress is firm while feeling like your sleeping on air it's as if the mattress forms around your body with alignment to support while you sleep. I often get hot during the night but it seems as if the mattress keeps me cool. My back posture has seemed to improve as well which is wonderful because I don't wake up sore on one side or the other. Overall I highly recommended this mattress my mom has severe back arthritis pain and I have recommended her to purchase this mattress also !!

Best night sleep in years!

Kyle 3/6/2025

Best night sleep I've had in years! I got this bed as a free promotion and I wasn't sure what to expect. I usually wake up several times a night and rotate my body, but since I've started sleeping on this mattress I wake up in the exact same position as when I fell asleep! I can see this mattress becoming a staple in my house in all the bedrooms. I wouldn't be surprised if my guest as where I got these mattresses from when they wake up on one after a solid nights sleep!

Is a great mattress

Nat 3/1/2025

The mattress is great. Is big and thick. It is more on the firm side than in the soft ( fluffy ) side. Nut is freat if you suffer from back pain at least for me. It looks very well made. I do recommend it.

Love this mattress

CatMom 2/28/2025

This mattress is extremely comfortable. I came from a mattress that was the old school innerspring that was over 10 years old that I loved. I was hesitant to switch over but I'm glad I did! This mattress was a transition but after a month of sleeping on it, I melt right in but still feel extremely supported. Looking at my sleep tracker, the time I stay asleep and the quality of sleep has gone way up. If you're looking at a new mattress, definitely put this on your list to check out. I will be getting this one for our guest room when it's time

Incredibly comfortable

CLynn 2/23/2025

We are using this as a guest bed but have tested several times ourselves. One of us prefers a firm bed while the other prefers cushioned, and somehow we both love this one. We both have had the best night of sleep on this mattress and are considering replacing our own now. We've had the same feedback from some guests, including one saying they woke up for the first time in years without their normal morning back pain. I absolutely recommend this one!

Great construction and build quality. This mattress is very firm which is what I need. The materials feel high quality and should last a long time.

Best Most Painfree Sleep EVER!!

Kayti 2/22/2025

Im 32 Ive had rheumatoid arthritis since I was 2, as well as fibromyalgia which makes my skin very sensitive and makes non painful stimuli pretty dang painful. This Dupont Hybrid II has made an insane difference in my quality of sleep, my duration of sleep, my comfort and reduced my pain. It is stiff enough to hold my weight as well as allow me to move the way thats needed to find a good position. It use to take me hours to fall asleep, now im out in 15 minutes! My back feels supported my hips are gently hugged and I sleep like a literal baby! I feel so blessed to have had this opportunity and that it has been such a good fit for me! Anyone who wants a sturdy yet soft supportive mattress will love this! Before this mattress my neck was so tight I've been getting vertigo and losing hearing in my right ear, Its now been over 2 weeks since those issues went away. I feel refreshed and my day starts a whole lot better now!

So Comfy and Perfect for Everyone in the Family

Francy 2/21/2025

We have purchased Sealy mattresses before and after trying others (including extremely expensive ones), we went back to Sealy. This hybrid is a perfect compromise for those who prefer semi-firm and those who prefer a plusher feel. We have only been using this specific mattress for a little over a week, but have enjoyed it. Highly suggest this for those in the market for a new mattress.

Luxurious Comfort and Cooling Support!

Cà Chua 2/19/2025

I received the Sealy Posturepedic Elite Hybrid Queen Mattress for free from BzzAgent in exchange for my honest review, and I couldn't be happier with the upgrade! Replacing my old mattress with this one has been a game-changer. This mattress offers a luxurious sleeping experience, featuring a sleek design and premium materials. Compared to my old mattress, the Sealy Posturepedic is incredibly soft and comfortable, yet it still provides excellent support. The cooling technology helps me fall asleep faster and improves overall sleep quality, making nights more restful. I'm so impressed that I plan to purchase one for my kids when it's time to replace their mattresses. I highly recommend this mattress to anyone looking for a luxurious, cooling, and supportive sleep experience!

Best sleep of my life

MayDay164 2/17/2025

I received this mattress for free in exchange for an honest review. I have slept on the mattress for the last two nights, and have truly never slept so well in my life! The memory foam layer on the top is so thick, like nothing I have ever slept on. The there is no movement whatsoever when one person moves, making this wonderful if you have someone that tosses a lot! I feel like I just melted into the bed when I laid down. I would buy this mattress for every bed in my house if I could! I love it!

Just what my back needed

HopeD 2/16/2025

The quality and comfort are impeccable! I never thought I'd enjoy a firm mattress, but it turns out, this is exactly what I needed for a good night's sleep. It's firm without being hard. After night one, I was already impressed. My husband and I have both never slept better. I used to wake up with back and hip pain and now that's not an issue. We are both comfortable, cool, and supported all through the night. I expect this to hold up for years to come. I recommend this mattress enough! Gifted by Sealy in exchange for my honest opinion.

Extreme comfort, restful sleep

aysays 2/14/2025

Wow, this mattress is a game changer. I usually wake up with an aching body and since I have been sleeping on this mattress, I wake up rested with no pain. This mattress is firm but it is not stiff so it's super comfortable and will give you the greatest sleep.
