    Finally found my bed

    I’ve purchased and returned many beds in the last two years. I bought the Serta CF1000 medium and returned it, was too firm. I’m a side sleeper and it gave me hip and shoulder pain. Serta was excellent handling my return. I upgraded to the CF3000 plush. Perfect!!!! There was no need to wait 30 days to give this mattress a great review. Very happy with my purchase and getting a good nights sleep and waking without hip and shoulder pain. Thanks Serta!


    Wish I had not purchased this mattress

    I’ve had this mattress around 2 months. I thought with the higher price and name brand this mattress would be perfect for me. I wake up in the middle of the night Every night with terrible back pain. I wish I had purchased from a retailer that allowed a try out period. I wouldn’t have kept this thing 2 days max.


    Not for me, ready to move on

    First the basics, height 5’5”, weight 165. Fibromyalgia sufferer. Former Serta iComfort Savant owner (LOVED it). I exchanged an iComfort CF4000 Plush because that mattress was never plush. It remained hard as a rock after 60 days, my hips and shoulders felt quite painful by morning. No pressure relief there. So onto the hybrid I went. Exchanged for the CF3000 Hybrid Plush, which was less money than the CF4000 Plush. I had to pay $100 for exchange only (no refund allowed) and received no refund of difference in price from my local store. Lesson #1- check out manufacturers site first. Serta had a much more fair/reasonable exchange/refund policy. Serta was fantastic in getting the mattress made and delivered to the store during Covid! Waiting time was only a few weeks. The Serta CF3000 Hybrid is well made! The outside covering of the mattress has strong seams and nice material. It is uniformly shaped with great corners. The sides are strong without being uncomfortable. The sides give a little but not too much. Serta didn’t cut any corners there. That’s where the good news ends for me. There is no cooling effect in this mattress, even though it’s rated for some of the highest cooling. I absolutely roast in it and every night spend time moving around searching for a “cool” spot. The “Plush” in this mattress is way too soft. I don’t know how Serta can call both of the beds I’ve had “Plush”, these two “Plush” beds are completely the opposite! Because this bed is so soft, that when I flip over to other side (start out on back, but predominantly a side sleeper) I literally have to use the opposite foot to give me leverage to do so. The softness doesn’t work for pressure relief and I’m back to sore shoulders, hips and back again. At least the CF4000 didn’t give me a backache. But I’m stuck now, over $3,500 invested and no where to go. I’m not trying to bash Serta, I’ve had good luck in the past. I realized that I have to look around more next time, there goes my Serta loyalty. Good news is I don’t think this mattress will last years, like the last Serta I had. I’ll probably be sinking to the box springs in a few years.


    Wasn't what I expected from Serta

    Bought the queen size CF3000 Hybrid Medium in late February 2021 based on salesman's recommendation. Way too firm for us so exchanged for Plush model about 4 weeks later. Within a month however for both models there were already deep impressions on both sides of bed and a 'ridge' in between us. I weigh less than 160lbs so I thought this strange. I assume the memory foam responds so maybe the springs give way? Either way for side sleepers this bed does not provide comfort. Wife and I both wake up with sore hips and shoulders. Wouldn't recommend this mattress


    Firm mattress with soft top

    I would describe as this a firm mattress with a plush top. I feel supported but has a softer top. It took a while to get used to it. I changed from an old unsupportive mattress with a 5” foam topper. That seemed really comfortable at first. Then after several months my back and hip pain became much worse. Was advised to buy a firmer mattress. I was able to go in store and try several of Serta’s mattresses before I decided on this one. After adjusting to the firmness I really like it and back pain has lessened. I use with the Serra Motion Essentials which makes sleeping on my back more tolerable.
