This mattress is very firm. There is plush, medium and firm. The label said it is a little under medium on the original sealed plastic wrap. I wonder if it was Miss marked? In time, I hope I can get used to it. It's nice and thick and a good quality. Except for the handles on the sides. One of them almost ripped off at the bottom, when I pulled to help lift it. I am 63 years old and I didn't even pull that hard.

The Delfino Nights pillowtop is a perfect match for the type of mattress we've been searching for. Best sleep in months with no more achy joints or sore back when we wake up in the morning. I am a side sleeper and my husband is a back sleeper and with the support this mattress gives both my husband and myself is 100% worth owning. I highly recommend this mattress to those who like a mattress with a more firmer feel even with the pillowtop.

[This review was collected as part of a promotion.] Sleeping tight with our new mattress from Serta! Very comfortable for the way we like to sleep and you can not feel if anyone is moving next to you. So no more waking up when your partner is restless because we're both comfortable now! Love it!

[This review was collected as part of a promotion.] I received a Serta Perfect Sleeper Delfino Night Medium Pillowtop mattress. To say I'm in love with my new mattress is an understatement; I loved my previous mattress and really did not think I could love another mattress even more! I was afraid this medium pillowtop was going to be too soft as my previous mattress was a cushion firm, but it's honestly the perfect level of support. I'm a side sleeper, and this mattress does well for my preferred sleeping position. It's soft enough to allow comfort where my bottom arm and hips don't go numb, but still responsive enough for me to move around on. It also works well for my partner who is a back sleeper. Furthermore, the foam in the pillowtop does well to minimize the movements between my partner and I, so we aren't disturbed by each other in the middle of the night. We both find this mattress incredibly cozy and have loved just laying in bed to hang out and taking extra naps for fun. (Bonus: this mattress definitely provides enough response for adult activities without making too much noise, and doesn't sag after!) Finally, sometimes mattresses can build and hold heat through the night. We find this mattress is well-designed in both the foam and upper quilt which makes it breathable and keeps us cool. We also love the edge response which makes it easy to sit on the mattress. I can tell this is a high-quality mattress that's going to last a long time. Now I just wish I knew what's an in-stock, comparable model of this mattress so I could purchase one for my parents!

[This review was collected as part of a promotion.] I bought this to replace my son’s mattress after he took his. It’s nice and thick so it bumps up the bed height. It’s firm but yet soft for my bony body. Some fir mattresses I get pressure spots but not this.

[This review was collected as part of a promotion.] I’ve only been sleeping on my Serta mattress for 2 weeks and I swear it has been the best sleep I’ve gotten in a long time. I usually have a bed topper but with this mattress I don’t need it anymore. I sleep better I dream better and I can’t really feel my husband when he gets off the bed. Oh yeah my cat loves it too.

[This review was collected as part of a promotion.] This Serta Delfino Night mattress had a great impact in my quality of life. I'm able to have uninterrupted blissful sleep. Thanks to the well balanced softness and firmness. I used to wake up due to back-pains, and restless. Now I can sleep through theñuuu

[This review was collected as part of a promotion.] I've been using this mattress for more than three months, and it has undeniably positively impacted the quality of my sleep. This mattress provides the ideal balance between comfort and firmness (it's not overly soft yet far from hard). I no longer feel when my boyfriend moves during the night. This has significantly improved my sleep quality. Additionally, the mattress seems to be constructed with good-quality materials, and the fabric covering it feels pleasant to the touch. I really appreciate the practical grey color of the mattress because it's less likely to show stains that might be challenging to clean. It's a thoughtful design choice that adds to the mattress's longevity. It gives the impression that it's built to last.

[This review was collected as part of a promotion.] This is a perfect mattress just like the name of perfect sleeper. I fell asleep within seconds when I first slept on it. The pillow top is pretty tick and super fluffy. The mattress support is medium firm that I like, so even the top is soft the bottom has good support system. I would recommend this as it is very comfortable mattress overall. It is also not hot when sleeping on it during night. Great sleep every night!

[This review was collected as part of a promotion.] So I got this mattress a month ago and wanted to leave a review for it. So I got the medium firmness for the mattress and my initial impression was that it’s on the more firm side of things. I’ve come to think it’s actually a really comfortable medium mattress. I feel like the pillow top makes for a nice cushion and then the firmness actually just feels supportive. I have always struggled to find a medium mattress that still supports my body. This mattress fits the bill and I’m extremely happy with it. If you want a comfortable medium firm mattress that is supportive, check this mattress out. It will break in a little more but overall stays supportive and comfortable.
