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.

Costumer service is horrible. Defective mattress.

Unhappy costumer 1/27/2026

I can feel the springs on the edges of The mattress. Sealy does not approve this as defective because you can not see it. You buy a mattress to feel comfortable not to look at. I'm going to be charged to return or exchange it. Sealy product and costumer service has gone down since the last mattress I bought.

Horrible after 3 months

Unhappy customer 12/26/2025

For reference, I am 5'4" and weigh 145 pounds. This bed was nice at first for a month, but it's causing so much back pain that I had to buy a wedge pillow to raise my legs to relieve the pressure on my lower back. Now, I have to buy a topper that is going to cost hundreds of dollars and hope that it helps. I would not recommend this bed to anyone.

Incredibly uncomfortable

Unhappy sleeper 11/16/2025

This mattress is very uncomfortable. It's supposed to be a medium but feels like an ultra plush. There's no support at all. You can easily feel the springs on this mattress. They stick out from the sides just brushing your leg against. I knew this wasn't an expensive mattress but its absolutely terrible. Wish I never bought it.

Poor Quality

Unhappy customers 10/25/2025

Upon receiving the Sealy Posturepedic Spring Tight Top Medium - Queen mattress my wife and I immediately saw the top fabric was not tight at all. The top fabric is not tight at all, as wrinkles cover the entire topside. The second problem is the unequal elevation, which is very obvious with highs and lows throughout, especially on one side. The third problem was the lack of cleanliness with the brand new mattress. We have a Sealy Posturepedic Spring mattress in our spare bedroom and it is nothing at all like the new one we just received. Perhaps this new one was just one of the warehouseman's resting places, as that is what it appears to be.

Undisclosed 9/9/2025

I've been sleeping on this baby a few weeks already and its been wonderful, it is so comfortable and gives my back really good support, really breathable doesn't hold the heat which is great for this hot weather, it seems its gonna hold up good for a long time, already moved places with it (that explains my lack of decorations) and the moving didn't affect it at all, pretty durable material. 100% recommend!

Sleeping on a cloud

Undisclosed 9/3/2025

Wow can I just say how incredibly soft and comfortable this mattress is! My daughter has had a bad back with aches and pains and she had a hard time sleeping, but now she can tell such a difference in her sleep. She is comfortable and can sleep all night and wake up refreshed. The mattress is not very cheap but I think for the value of it it's definitely worth it. It's very soft and I think it's good breathable material. It's Designed with orthopedic specialists for specific support where you need it, improving spinal alignment. I'm so happy to have gotten to try this product out!! This was free for my honest review!

This mattress will have you going to bed early just so you can enjoy it a bit longer! The support is out of this world! I dont wake up with aches and pains like i did with my older mattress. Its seems to be a bit more breathable than my old mattress, too! All together its around a 12in-13in mattress, so not too thin but not insanely thick, either. It does have Posturepedic support system features, which is to die for! I honestly have only good things to say about this mattress.

Firm pressure relief matress that helped me with my back pain. It supports very nicely and gives you a comfirtable sleep. Its a very thick matress so it would last long beforw ypu see it cave in. Its a good price for the type of matress. Its also breathable is not super hard but firm.

So comfy! Helps my sleep

Undisclosed 8/25/2025

I've been sleeping on the Sealy Medina II Firm Spring Mattress for a few weeks now, and I can honestly say it's been a great upgrade. The firm support is noticeable right away - it feels sturdy without being uncomfortable, which is perfect for me since I prefer a mattress that keeps my back supported. What surprised me most is how balanced it feels: it's firm enough for proper support, but the top still has just enough cushioning to make it comfortable for longer stretches of sleep. I also noticed I'm waking up with less stiffness in my shoulders and lower back compared to my old mattress. The quality feels really solid, and I love that Sealy has a trusted reputation. Overall, it's a great option if you want a mattress that combines reliable support with lasting comfort.

Super supportive of all sleeping positions

Undisclosed 8/25/2025

I have slept so well on this mattress. I'm sleeping on my back as well as on either side! I normally sleep on my left side due to hearing loss but on this mattress, I'm comfortable in any sleep position. This mattress isn't too soft or firm and my body adapted to shifting through out the night. Even getting to the edge of the mattress is comfortable. The end coil of the mattress was always there to irritate and remind me it was there. Not with my new mattress! All I feel is comfort. The mattress has a medium-soft feel with just enough plushness without sinking into the mattress. I found this to be a great balance for my needs. As a back sleeper, I felt my spine was well-supported, and there was enough lumbar support to keep my lower back happy. Side sleeping felt comfortable too; the cushioning was adequate for my shoulders and hips, though I didn't feel a deep "sinking" sensation like with some memory foam mattresses I'd tested. Excellent pressure relief for back and side sleeping, Good motion isolation and versatile for different sleeping positions when I rolled over to change positions.

At first, I thought this was way too hard. Sitting on it felt tight BUT that first night, I slept so good. I was so supported I could turn over at night with no back pain. Over the month, I've been sleeping so deeply and have been feeling so refreshed in the mornings. Absolutely recommend this mattress!

One heck of a mattress

Undisclosed 8/21/2025

WOW, just WOW. This is such a comfortable mattress. Just the right amount of soft/firmness and the mattress material itself is so soft (sheets almost not required other than they are) My youngest had officially outgrown the twin and was in desperate need of a bed when I got the notification for this beauty. It supports his growing body and so far has withstood the life of a pretend boys bed. Did I mention how comfortable it is?

Just right luxurious comfort

Undisclosed 8/17/2025

This mattress is incredibly comfortable. It is supportive but just the right amount of softness. It is on the firmer side, but the soft pillow top allows you to sink in a bit to get that cradling feeling. I relate it to the goldilocks of mattresses because it's just right! It also feels incredibly luxurious, like a hotel bed. It is currently located in our son's bedroom, but I find myself preferring to sleep in there over my own mattress! It is breathable, and I don't find myself getting hot or sweaty as with some other mattresses. The print on the mattress top itself is bold and might show through lighter colored sheets. A mattress protector will solve that though. Overall this is an excellent mattress that I wholeheartedly recommend!

Soft and affordable with solid support‚ but sleeps

Undisclosed 8/14/2025

From the very first night, I slept deeply and comfortably. The mattress feels cushioned yet supportive - truly "soft but firm." The coil system responds well and keeps my spine aligned. I barely feel any movement when my partner changes positions, which makes it excellent for couples. It tends to retain a bit of heat, which I noticed more on warmer nights. If you're a hot sleeper, this might be something to keep in mind.

I am so impressed and happy with this mattress. This mattress is soft, but sturdy. Its fluffy, but you also dont sink right down. The springs are also undetectable. This mattress is in my daughter's room, who at an elementary age was still waking up multiple times a night. She has slept through the night all but once this week, I have both laid and slept in the bed, and as someone who's body is extremely sensitive to changes like this, I woke up and felt no aches or pains. I can see why Sealy is such a reliable mattress company, thank you!!

Very supportive, just too firm for me.

Undisclosed 8/11/2025

Okay, first, the bed is deep. At least 12 inches deep. Firm, and I'm not sure if it has to be "broken in" but night one, I had some back issues. However, my husband who was having back issues from our pillow top mattress, loves this mattress and feels very supported. So, it's not pillow top but also not super firm, it has some give and after a few nights, maybe it'll soften up a bit. Overall, not a bad mattress at all, just too firm for me.

Absolute Game-changer of a Mattress - Saved my Back

Undisclosed 8/4/2025

THIS MATTRESS HAS SAVED MY LIFE. Previously we had a foam mattress and it quickly lost its structural integrity. It was sinking and sagging and the edges were non-existent and I actually fell out of bed while sleeping a couple times. This mattress is sturdy AND comfy. I was a little hesitant about getting a firm mattress but I'd been considering the idea for a while and man, I'm glad I finally went with it. This bed isn't so firm that it's like a rock. It has give where needed and keeps the legs, back, neck, and head supported. This mattress has also SAVED my back. I have some back problems that were exacerbated by the old mattress because of zero support and this mattress has improved my sleep and my back health, which has given me a new lease on life. Admittedly, the first few days of having this mattress my partner and I slept A LOT because it was like we finally could. I definitely recommend this mattress and I recommend the firm if you're already considering going that direction with your mattress. As for value, well, you really can't put a price on good sleep and this is one area where you shouldn't skimp - trust me, we made that mistake before and never again.

Big improvement

Satisfied Sleep Maestro 8/2/2025

This was a replacement for my 20-year old son's mattress. I had, recently, gone into his room to talk with him about something and realized that his mattress was truly worn out and was showing signs of damage. I was, actually, embarrassed by the condition that his previous mattress was in. I had noticed a protruding spring close to a year ago but I was surprised by the amount of deterioration and the quick rate that his previous mattress had deteriorated. Although I don't use or experience his mattress on a regular basis, my son has expressed, to me, how much more comfortable his Sealy mattress is and how much better he has been sleeping since we replaced his mattress. I would have to say that WE are very happy with our Sealy mattress and wouldn't trade it for anything or any other brand of mattress.

First Impressions: Sealy Posturepedic Medina II Ma

Undisclosed 8/1/2025

It's been 2 nights sleeping on this mattress, and so far I'm really impressed. It's definitely softer than my old mattress, but not in a way that feels unsupportive. It's that perfect mix-firm underneath but soft and comfy on top. Almost like you're being cradled without sinking too deep. I didn't wake up stiff or sore, which is a big win for me. It feels like it molds to your body just enough, but still gives that solid support. If you're someone who needs both comfort and structure in a mattress, this one might be your sweet spot. Can't wait to see how it holds up over time! Received complimentary through Influenster for testing purposes

Get ready for a great sleep. This mattress is not only comfortable but provides great all over support for your body. It's has lots of breathability so you don't get over heated. It's definitely a high value product. You don't have to add a whole lot of extras to this bed like memory foam or pillow tops because it's already pretty soft. If you're looking for a high quality mattress this is definitely a great one. Sealy always delivers great value products.
