Ultra Firm

Ultra firm mattresses are not for everyone. You have to understand that this mattress is nothing like any of prior mattresses you have used. It will shock you the first time you lay down on it, But !

Once you use this Ultra firm mattress for a few weeks and break it in , you will no longer be able to sleep on regular mattresses like firm, medium or soft. 

Everyone says that their mattress is the best mattress ever but it’s relative. This is an excellent mattress that has excellent support and I believe that is much healthier for your back and body

This is an excellent mattress

[This review was collected as part of a promotion.] Oh my gosh. This bed is beyond comfortable. I have a lot of pain from playing sports and I have slept so good lately because of this bed. You can stand on it and it doesn’t sink that bad or move the other person. It is supportive in all the right places. I love this bed so much.

Omg this bed is so comfy.

[This review was collected as part of a promotion.] ⭐️⭐️⭐️⭐️⭐️
This mattress offers the perfect balance between comfort and support. The firmness level is just right—soft enough to feel cozy but firm enough to keep my back aligned all night. I wake up feeling refreshed with no aches or stiffness. The breathable fabric helps keep me cool, even during warmer nights, and the build quality feels premium and durable. The side handles make rotating and moving the mattress much easier. Definitely a worthwhile investment for quality sleep.

Love

[This review was collected as part of a promotion.] The Sealy Paterson II Ultra Firm mattress has amazing support and firmness, which really helps with back pain and posture. It feels very durable and well made, and even though it’s extra firm, it’s still comfortable to sleep on. I also like that it has good breathability, so it doesn’t trap heat and keeps me cool all night. Overall, it’s a great balance of firmness, comfort, and durability.

Great support and firmness with lasting durability

[This review was collected as part of a promotion.] I love the Sealy Paterson II Posturpedic Plus Spring, Ultra Firm Mattress! My sleep has significantly improved over the course of a month. I get up in the morning with less aches, especially in my hips and back. The mattress is very firm, but it feels really soft to the touch. The mattress is pretty thick, so you will need bed sheets with deep pockets. If you are looking for a more firm mattress that has really great quality, I would definitely recommend this mattress to anyone in need of more support for their body when sleeping. I will definitely consider purchasing Sealy mattresses in the future, and I would recommend it to my family and friends.

Restful Sleep!

[This review was collected as part of a promotion.] If one is looking for an ultra firm mattress the “Sealy Paterson II Posturepedic Plus Spring Ultra Firm” is the perfect mattress. In my opinion the mattress is comfortable and durable. It also provides great breathability and support. I definitely recommend.

Great “Ultra Firm” Mattress!

[This review was collected as part of a promotion.] The Sealy Posturepedic Paterson II Ultra Firm is a very supportive spring mattress ideal for back and stomach sleepers—especially heavier sleepers—thanks to its strong coil system, solid edge support, and cool feel. It gives a luxurious and comfortable cozy feeling while you have to end your day.

Pros: Excellent firmness, good spinal support, sleeps cool, durable structure.
Cons: Too firm for most side sleepers, minimal pressure relief, may feel uncomfortably stiff for lighter people.

I have back pain and this is by far a best investment.

Have recommended to my friends and they love it.

Firm sealy mattress

[This review was collected as part of a promotion.] I was asked by Influencer to try this product in return for my honest and unbiased opinion Seale's Patterson II posturepedics plus spring ultra firm has to be the most comfortable mattress I have ever been able to lay my body on. Just having to have emergency hamstring reattachment surgery to where I was laid up in bed for almost 6 weeks I was so afraid that I wouldn't be comfortable and not be able to get any rest to heal. That couldn't have been further from the truth. This mattress is firm and holds my body. I don't "sink in" like foam mattresses. It has just enough give in the padding on the very top so that you know you're not laying on " a board".  I can only be comfortable being on firm mattresses and this is extremely helpful to my back and to my recovery for my hamstring. I wouldn't give this mattress up if God himself asked me for it. This mattress is that good and it's beautiful!.

Finally a FIRM mattress

[This review was collected as part of a promotion.] This is my first time using the Sealy mattress and I'm super excited and impressed. The mattress is very comfortable and built with quality. The mattress is very firm and can withstand a great amount of weight to it. It does not get hot and stays cool throughout the night. It was very easy to install. Much more comfortable than other mattresses and I highly recommend it .

Fantastic

The mattress itself is well-made and seems durable, but it was too firm for my needs. The description of ultra-firm is 100% accurate. It was like sleeping on top of a blanket laid on concrete. The true issue was the horrible support for the return process. I spent literal hours on the phone and emailing Sam's support, getting pick up scheduled, etc. And even after pickup the credit took 15 calendar days (10 business days) before it happened, and it only happened after I emailed and called AGAIN after not recieving the credit in the 5-7 business days that were originally estimated.

Don't Buy From Sam's - Return Process horrendous
