Got this for my guest bedroom and so far, I’ve had nothing but compliments on how comfortable this is. Great buy for the price!

Comfy

The best mattress makes your body feel calm 😍

I have chronic pain health problems with my lower back, legs, neck, shoulders. This ultra firm sealy posturepedic parada firm queen mattress is a perfect fit for me. I sleep comfortable with this mattress and I can tell it does help these issues. I had a old sealy Posturepedic pillow top for around 17 years and it was great also, but knew it was time for a new one. Sealy Posturepedic has always been my choice! I paired this mattress with an adjustable base instead of a box foundation for the first time in my life, so alongside with that it's perfect! No more waking up with leg pains and back pains!

SEALY PARADA ULTRA FIRM QUEEN MATTRESS

I needed a new mattress and so I went to Mattress Firm in light house point , Pompano Beach FloridaA young salesperson, Jason provided information as needed and was a great help in my making the perfect choice for me. Normally I do not like sales people moving in before I have had a chance to look around and formulate questions but this young man was never intrusive and it felt more like dealing with a friend offering advise. I enjoyed working with him and credit him with my being able to make the perfect choice for me. I decided on Tempur-ProAdapt 12' firm mattress It was delivered promptly and carefully. Thanks to it I had the best night's sleep I have had in several months. I am so happy with it. Sincerely, Bernice OConnell

Great Experience

Sealy has always been a top of the line product. The foam mattress has been awesome. I am allowed to sleep in comfort without tossing alot. Thanks to my sales lady for her recommendation. It's my first purchase of this kind.

Comfort and Quality

Mattress is very comfortable not too firm. Pillowtop makes a big difference for me. No more waking up with sore shoulders Hopefully it'll withhold in time .

Comfort

First off, not getting paid for this. I wish i was but im not. With that out of the way id say this mattress is a great deal for the price, its comfortable and has a surprising amount of support, despite not having springs. A con i would say is if the mattress cools down it starts to get hard.

Quiet Comfort

It was described as medium firm and it is much softer and "mushy".... it's for my 3 year old grandson so it will work but if it was for an adult I don't think it would keep its shape very long. The appearance of the mattress is very nice.

It's much softer than I expected

we purchased this mattress 10 yrs ago at Rooms to Go. It only had support for 1-2 yrs, and we only are here half they year. we have 2 canoes in the mattress. Thought an extra mattress top pad would help. We suffered through and finally bought a new Foster Sterns. Should have done it hears ago. I called the company and the warranty didn't hold. Big disappointment.

Sealy lineage night bloom, only good for 1-2 yrs

Unsatisfied. It's supposed to be a firm mattress but it is not. There are already depressions where we sleep at only 6 months old. We have turned the mattress 1/4 turns until we went around once with the same results, divets!
