“Nice matress but wish it was a little more firm”

Angelbert Casido

“It sounds like you’re enjoying your mattress but were hoping for a bit more firmness. If you’re looking for a more supportive feel, adding a mattress topper or adjusting the base could help.”

Beautiful Rest

⭐ ⭐ ⭐ ⭐ ⭐ (5/5)

“First night on my new Beautyrest hybrid Harmony Lux bed was so comfortable I didn’t wake up during the night or want to get out of bed! I’m in my late 50’s and have slept on many beds over the years. I’m a side sleeper with my neck fused and been dealing with a lot of issues, especially with my shoulders and arms. This bed has helped so much.”

Firm yet plush

⭐ ⭐ ⭐ ⭐ ☆ (4/5)

“I am thrilled to share my experience with the Harmony Lux Hybrid mattress. As a side sleeper, I need a mattress that can provide adequate support to my back while being comfortable enough for a good night's sleep. And the Harmony Lux Hybrid mattress does not disappoint ( yay!). The mattress consists of several layers of foam and coils, which work together to provide the perfect balance of support and plushness.Overall, the Harmony Lux Hybrid mattress has exceeded my expectations. It provides enough support to my back without feeling too stiff or uncomfortable and has just the right amount of plushness to make me feel like I'm sleeping on a cloud. I highly recommend this mattress to anyone ( especially those who are very active or need extra support without the stiffness) looking for a premium-quality mattress that offers support and comfort.”

Amzingly comfortable

⭐ ⭐ ⭐ ⭐ ⭐ (5/5)

“This has to be, by far, the most comfortable mattress I've ever slept on. It's on the softer, more cushy side and the pillowtop type style microfiber is dreamy, pun intended. It's incredibly plush and comfortable. It's on the thicker side too, meaning it's suitable for a heavier person and you won't "sink" in. You can immediately tell that this mattress was made to last a while. Excellent craftmanship and durability. I highly recommend”

Love My Mattress!!!

⭐ ⭐ ⭐ ⭐ ⭐ (5/5)

“I have to say I was a little worried about a new mattress. We had a water bet for over 25 years. Yes I know Wow… We bought are first mattress 11 months ago.. I never got comfortable on it and had trouble waking up all hours of the night with my arms and hands hurting and numb.. First couple of nights, no hurting and no numbness.. I thought, ok.. We’ll guess what, I have still have not had any numbness or pain.. I’m in LOVE.. I sleep like a baby on this thing.. Thank You!!!!”

Plush, but offers support

⭐ ⭐ ⭐ ⭐ ☆ (4/5)

“I set up this mattress in my bedroom, on top of a 6" box spring, to ensure that the mattress would have a good foundation and I could rate the mattress accurately. When delivered, I noted that it was quite heavy and felt very plush. I was afraid that the bed would be uncomfortably soft. After several nights of sleep, I was surprised to learn that the bed is actually more supportive than expected, which works well for me, as a side sleeper. It's plush, but still offers support. When watching TV in bed, though, I noticed that I did not feel as comfortable laying flat on my back for extended periods of time. I had read that the bed had built-in cooling properties, but didn't really feel any difference in cooling. To be sure of this assessment, I changed the sheets to cooling bamboo sheets and made sure that I wasn't using any sheets with microfiber (which retains heat), and did feel that it helped. For this description, though, I expected a bit more. What I love about the bed is that it is made from innovative technology, using recycled plastic bottles, although the bed itself in no way feels like it is. If I hadn't known, I would still feel that this mattress is a high quality product made from traditional materials. Overall, the mattress is a well-made, plush, and comfortable one, which works well for side sleepers. It's a good medium that offers the best of both worlds for the Goldilocks in you - not too soft, and not too firm.”

Love it!

“I had a much needed restful night, My significant other likes it and also had a good night’s rest. It’s not as plush as expected but I was not disappointed at all. At first I felt as if it was too firm and I was going to wake up feeling aches and pains but I was so wrong. The firmness and support are perfect. The mattress is about 14 inches tall, time to buy new sheets(smiling). The quality is great. I look forward to more restful nights.”

So plush and perfect sleep mattress

⭐ ⭐ ⭐ ⭐ ⭐ (5/5)

“This mattress is like sleeping on a cloud! It is very plush and the first thing I noticed was how thick it was (about 13 inches thick) and just feels like quality. It has a cooling feel if you lay on it without a sheet on or with a thin sheet. The mattress details on top has like ripples in the pattern which is very soothing and almost massage like when you move around in the bed. The mattress is in a blue, gray, and white color combination which gives a relaxing and soothing feel. I can see how it got it’s name because it does remind me of ocean waves in the pattern and reminds me of relaxing by the sea. In my previous experience, I feel like sometimes mattresses need time to adjust before you feel truly comfortable and after sleeping a few weeks on this mattress, I don’t think I really had to adjust like it was already comfortable and very plush to start with from the beginning. Just for reference, I got the Beautyrest Harmony Lux Hybrid Seabrook Island in the plush firmness in size queen. This was the perfect size I needed for the spare bed in my office/guest bedroom.”

Sleeping on a cloud

⭐ ⭐ ⭐ ⭐ ⭐ (5/5)

“I am very impressed at how much of a difference this mattress has made in my nights sleep . The mattress not only helped so much with back pains, I’ve noticed a huge difference in the way my husband sleeps as well . Very soft but has just the right amount of firmness to keep comfort . Sturdy and no sinkage at all . This is top of the line and perfection if you ask me . I will definitely recommend to anyone in the market for a new set .”

Best Sleep of My Life

⭐ ⭐ ⭐ ⭐ ⭐ (5/5)

“This mattress is the most comfortable mattress I've ever slept on. You sink into the plush top and it molds perfectly to your body with the memory foam contouring perfectly to you. Once you get off the bed it goes right back to its original place. When you touch the mattress, it feels cool and pulls the heat away from my body making it easier to fall asleep, especially in hot California. I love the design and colors so when I'm washing sheets and the mattress pad you don't feel self-conscious about seeing any marks and it's very easy to clean off marks if needed. When I move around it's not disturbing the person next to me and doesn't make noises. When contouring to my body it's help relive my lower back pain and I wake up well rested and joyful.”

“This mattress is used in the master bedroom. This mattress is plush and comfortable. The thickness of the mattress helped provide a wonderful sleeping experience. I have not had a good night's sleep in a long time. I slept like a baby the very first night! Superb product!”

Amazing!

⭐ ⭐ ⭐ ⭐ ⭐ (5/5)

“This mattress is an absolute dream! I'm mainly a side sleeper and have had hip pains since having my kiddo 9 years ago. Switched to this mattress and after about a week, no more hip pain! I use to have to get up and readjust or flip to the other side because of my hips, but now I sleep soundly! Its a deep mattress that cradles your body and isnjust heaven! The delivery service is top notch too!”

Game-changer for side sleepers!

⭐ ⭐ ⭐ ⭐ ⭐ (5/5)

“As a busy and tired mom of three young kids, I have forgot what a good night's sleep is until I got this mattress. I absolutely LOVE this mattress! I'm a side sleeper and the Harmony Lux Seabrook plush is AMAZING!! It contours to my body and I feel like I'm laying on cloud. It's soft but supportive! I have scoliosis so it's usually hard for me to get comfortable and as a result, I usually toss and turn at night. However, my husband pointed out that I haven't really tossed or turned this much this week with the new mattress. I am also loving the cooling technology because these socal nights are warm and I usually wake up all sweaty but I haven't had that all week. I have only had the mattress for a little over a week but I have never felt so refreshed! My kids love it too and I was able to lay my son on it for his nap without him waking up! He woke up happy and asked if can sleep on it daily. Another added bonus about this mattress is that it is ecological friendly (upcycling of plastics) and with three young kids, I want to my part in providing a better environment for them! However, I do have to warn you that it's so comfortable, that it has been really hard to get up in the mornings! Definitely a game-changer for busy mama like me and absolutely loving every night's sleep!”

This mattress has a memory foam that forms to my body and makes sleeping possible. Has motion control to where the besd doesnt bounce all over the place when laying down or moving around. I love the fabric and the way it is made.”
