I was not able to test this mattress so I relied on the manufacturer rating to make my purchase decision. So, on a scale of 1 to 10 (with a 10 being the most firm), this mattress was rated (by the manufacturer) at a medium comfort level between 4 and 5; however, it feels more like a very firm 8 or 9. Unfortunately, I don't think this unexpected extra firmness will work well for a side sleeper like myself. My advice would be to make sure you can test this mattress yourself and do not rely on the manufacturer's rating to make your purchase decision. My only hope is that, ove time, it will soften enough so I will be able to "comfortably" sleep on my side.

[This review was collected as part of a promotion.] This mattress replaced a super old me with foam mattress. I have slept on it and woke up feeling refreshed and had a good nights sleep. It's very soft, yet firm. It has just the right amount of softness but still leaves plenty of room for support.

The firstKing mattress sagged where each of us slept after 3 months (180# each). Got replacement and this also has sagged and results in uncomfortable sleeping. Feels like sleeping in a hammock. Sterns and Foster will not help as we bought from "Mattress Firm". So I guess they dont care about their reputation or quality of this product. I am extremely unhappy with my $ 3000 purchase.

DO NOT SHOP AT BEST MATTRESS. This place will take your money!! I went with a mattress here and in total spent almost 5K. I was told that if I didn't like my mattress, I could exchange it within 30 days. The mattress arrived and immediately I noticed it felt COMPLETELY different and stiffer from the one I tried. I bought the matching protector with it, but after a couple weeks I was too uncomfortable and decided to exchange it with a similar mattress. The deliverers came to pick it up but they would not take it due to it being "stained." This was supposedly a new mattress paired with a quality mattress protector that I have only had for a couple weeks!! They came to the apartment without a new mattress, had dirty shoes without foot covers on, and dirty gloves. They came in without a purpose to deliver a new mattress. They refused to do the exchange that they promised me due to the stain that I have never seen. I am stuck with this mattress that was 1- sold to me already used or 2- stepped on by the delivery drivers. I have been treated HORRIBLY by customer service when I paid good money for this mattress. This company is only out to get your money and will not help you.

[This review was collected as part of a promotion.] I originally wanted to put this in our guest room but it's so comfy I think I want it in my master bedroom instead of my TempurPedic! Perfect medium firmness with the pillow top adding a little extra cushion. I have been using this for 2 weeks now and have had no issues sleeping on my back, side or stomach. I love that it is compatible with an adjustable base as we will be getting that in the future. The only reason I would give it less than 5 stars would be because the price point is pretty high with it being Stearns and Fosters cheapest line but it is definitely worth it! *I received this product free of charge in exchange for my honest review*

[This review was collected as part of a promotion.] This bed is extremely comfortable. It is soft and firm at the same time. The pillow top is plush and adds an extra level of comfort to the bed. I have used a sleep number bed for years and never thought I would start from it but this bed has made me rethink that! Love, love, love this mattress!

Our Stearns & Foster Studio 14" Medium Tight Top King Prime mattress is incredible. We'd had our old mattress for 27 years & didn't know how bad it was. Sleeping on our new mattress is like a whole new day, everyday. Our sleep is soooo much better & we wake up being able to function much better. We added the Stearns & Foster 300 Adjustable base, because my husband has sleep apnea. Using the remote, he's got the head of the bed very slightly elevated & this has made a huge difference in both his sleep apnea & his snoring. We're very happy customers!

[This review was collected as part of a promotion.] We've been needing a new mattress for a while now and after trying multiple mattresses and price points, we decided to go with the Stearns and Foster Studio Firm Tight Top. This mattress is sooooooooo comfortable, plush but not to soft. We enjoy the firm tight top due to slight back problems. The mattress is a beautiful dark blue in color and it's a little higher (with the box springs) than we're used to. I feel like a Queen laying on top of this mattress and whether I'm sleeping or sitting up relaxing, my back pain hasn't been an issue. I'm looking forward to many, many good night sleeps on my new Stearns & Foster mattress.

[This review was collected as part of a promotion.] I believe good sleep in the night will be a best kick start for a healthy and happier day. I love resting on this mattress. It gives me best sleep with no complaints. It's a thicker mattress. It feels that it contours your body giving required support to the sides you choose to sleep. It is firm enough to help my back but still has good cushioning. This is exactly want I want in my bedroom. I feel very relaxing and super comfortable sleeping on this mattress. The material is too good and the quality is amazing. Top portion of this mattress is well made with attractive design on it. Felt rested and super refreshed after waking up. Quality is excellent too. I would definitely recommend this.

[This review was collected as part of a promotion.] I received the Stearns & Foster Studio Medium Pillowtop Queen Mattress and I love it! Not only is this the most beautifully designed mattress, but it is also some of the best nights sleep I have ever had. I love the comfort of a pillowtop mattress, but I needed more support for my back. With this Medium support pillowtop mattress I can now have both. The pillowtop contoured to my body giving me the best comfort and the support was not too firm and not too soft. It was perfect. I can wake up and not have soreness in my back and that is huge for me. The mattress has a ventilated cooling system that helps to keep your mattress cool all night long. The coils have responsive innerspring technology that prevents noticeable movement from your partner so you can have a more uninterrupted sleep. My husband does toss and turn in his sleep and I didn't notice his movements at all while sleeping on this mattress. I was able to get a good nights sleep and woke up feeling refreshed and ready to go. I haven't felt this well rested in years. I am very happy with this mattress and I would definitely recommend it to all my family and friends.
