Amazing mattress! Ladyc20 ·
Recommended Not Recommended

[This review was collected as part of a promotion.] Oh my goodness!! This plush mattress is amazing!! It was delivered and packaged well. They even took my old mattress so I was happy about that. It fit perfectly in our room. This is my first memory foam mattress so the first couple of days I had to get use to it but OMG!! I've been sleeping so much better now. Before getting the new mattress, I would sleep for maybe 6 hours but getting up a couple of times a night. Now I'm sleeping almost 8 hours straight. It feels so amazing waking up we'll rested. Such a comfortable mattress!!

One huge expensive mistake Mickey50 ·

After having slept on the I comfort memory foam and loving it my husband and I purchased the new guy comfort hybrid in October 2019 it has now been about 18 months and I have to say sleeping on this mattress is like sleeping on the road with potholes. I have had two back surgeries and all I want is a good nights sleep which I never get from this mattress I feel like I’m either sleeping uphill or downhill or in a hole it is by far the absolute worst buy my husband and I have ever made. My back hurts so bad when I wake up in the morning I could just cry. we would never recommend this mattress to anyone

NOT A FULL SIZE MATTRESS chris03811 ·
Recommended Not Recommended

This mattress is not full the full size length of 25 inches a advertised. Its only 74" and it makes a difference to me as my toes touch the edge and swoop down.



Hard as rock Quintcy84 ·
Recommended Not Recommended

Paid a lot of money for a plush mattress with no springs but I do believe the floor would be a softer option. Could barely move in the morning will have to resort to sleeping on my soft sofa again very disappointed very hard bed.

Not as plush as my old Icomfort plush matrress Rdunkleenr2d ·
Recommended Not Recommended

I had an IComfort plush mattress for 9nyears. I decided to replace it. I bought it through a local dealer on line. It was delivered and I immediately sat on it to check the comfort level. With the old mattress when it was delivered I sank down into a cloud of heavenly comfort. This new CF3000 feels like like it has the comfort level of laying on a board. The tag says “Plus” but as far as I’m concerned it is at least medium if not firm. I called the retailer an they said it could take up to 3-4 weeks to achieve the plush comfort level. My old iComfort was Plush as soon as it was delivered. I’ll give it a week then see where it is at with the comfort level.

Hi there. Thank you for taking the time to leave a review. We are sorry to hear that the mattress is too firm for you. New mattresses can sometimes have a break-in period when it’s first slept on. During that time, the new foam will soften slightly and gradually provide improved pressure relief. If after sleeping on the mattress for more than a few weeks, it is still too firm, please contact us at 1-888-557-3782. Thank you.

Very comfortable for sure! TonyG ·

I am very satisfied with this mattress and so glad I have chosen the CF 4000 Plush Serta! I now fall asleep quicker and sleep more soundly through the night. Most of the back pain (which had been getting worse) has diminished significantly. I would highly recommend this product to anyone looking to replace their mattress.

Don’t buy it CassieJ1025 ·
Recommended Not Recommended

I have had my king mattress for 5-6 years. It was firm when I bought it and it’s named and marketed as FIRM. now it’s like sleeping in a pit. It also will not lay flat anymore and I only weigh 140lbs. Hugely disappointed and not Worth the $$ spent. I should have and could have bought a tempurpedic with how much I spent. And I just discovered today that the layers are not even in a solid encasement. No wonder the sheets don’t stay on the bed all the layers inside move every time you move and not just up and down. So so dissatisfied.

Doesn’t hold up Ben1999 ·
Recommended Not Recommended

Was great for the first few months but soon my wife and I were sleeping in the trenches made by the collapsing mattress. We often had to “climb the ridge” in order to kiss goodnight. After a year, we are in the market for a new mattress because we both are having back and neck issues. Definitely does not hold up over time. We’re average weight, probably less than average really, and the mattress just sagged over time. We rotated (not suppose to flip this kind) but that just meant my wife would sleep in my trench and I would sleep in hers.

We tried the mattress in the store and that one was a soft, fluffy dream cloud. After saving up money to purchase the mattress which is also the price of a used car, and then waiting OVER a MONTH for the mattress to arrive we were disappointed when we had a hard mattress. I "aired" the mattress out upon arrival as directed. I also walked on the mattress to loosen the fibers. I know some people might say that our bodies just need to adjust to the mattress, well it's been a month now the mattress still feels like we are sleeping on a metal table.

My 3 month impression Jackie287 ·
Recommended Not Recommended

[This review was collected as part of a promotion.] I have owned this bed for about 3 months. It is a good firm bed ....it feels soft enough to keep you afloat with strong support underneath. I love firm beds and enjoy this bed. A small con is that you may feel “stuck” or sunken depending on position that you were in. This doesn’t happen often but I’ve already encountered this. I think this is due to memory foam. I think over time this bed may loose its firmness due to memory foam giving way. Honestly I think this bed can last as it is for 5 years....10 years if you are really lucky and just have kids or lightweight people sleep on it.
