  • Best sleep in a long time
Style: 10 inch Hybrid mattress Size: King
Bot I and my boyfriend have bad backs, and this matress is just firm enough to ease the pain at night... perhaps maybe just a bit to firm for me, but great for him. I was very skeptical at first about buying a mattress without physically seeing it first. We waited about 4 days before sleeping in it to make sure that it expanded all the way. The only down fall is that any major movement from him at night I can feel, or the pup moving around. It's motion isolation is for very very minor movement. It's been a week not yet disappointed. ... show more

  • Firm. Quite firm
Style: 12 inch Hybrid mattress Size: Full
This 12 inch mattress is super firm, but very supportive. I sleep excellently in this bed. Yes, there is no side support, but once you know that, prior to buying ( by reading reviews) , you would have bought quite a firm and supportive bed for sleeping. I dont know if the build quality is uniform because some people say they sink into it and its like sleeping on clouds, but for me it was not soft at all. But my body does not do well with soft beds because I am no princess. But I bought this bed because as a side sleeper, my previous all-memory foam bed which I had for 10 years was begining to hurt to sleep on. My hips were hurting, my back was hurting as well. But with this bed, all those issues are gone.... I never knew a bed could make such a difference. These days when I wake up, I wake up super refreshed, even after a few hours. This bed is easy to get sleepy on. ... show more

  • It feels amazing
Style: 12 inch Hybrid mattress Size: Queen
1st things 1st, I’m a heavy woman! Can I tell you how I float on this bed like I way nothing. I did wait almost the entire time the manufacturer recommended for expansion. I don’t make it a habit of sitting on the side of the bed, however the longer I’ve had it, the more stable the edges seem to get. It is a bed in a box so…. For me a bed that was squash up in a vacuum seal and smashed in to a box is bond to take a moment to get the edges together. All and all though, this bed feels absolutely amazing. I’ve paid WAY more for beds in the past and this is the best sleep that I’ve had in a very very long time. It’s not soft and it’s not hard. It’s not “medium” either. I would say it’s sturdy. As long as you’re realistic in your expectations, you’ll be satisfied! ... show more

  • Comfortable
Style: 12inch Hybrid mattress Size: King
I’ve only had this mattress for a couple of days now, but I can say it is very comfortable. It was easy to unbox and “inflated” quickly. I purchased the medium firmness and it feels just right. I don’t sink into the mattress, but it has some give. There is a slight odor to it, but it’s not bad. I’m sure it will dissipate. It hasn’t affected my sleep. The only “issue” I have is that when you sit on the edge of the bed there is a lot of give or sag. I’m only 118 lbs so someone heavier may not like this. My traditional mattress edge stayed firm. This is the only problem I can see. Still, I’m very happy with this mattress. It was a great value for the price. Side note… when I opened the box the instructions said to unbox within 72 hrs of delivery. That would be helpful to have on the OUTSIDE of the box otherwise how would you know that?! I didn’t open for almost a week because I was waiting for my bed frame. I don’t think it mattered, but if that is important, the company should put it on the box. ... show more

  • Way better than my Serta-Simmons Beautyrest!
Style: 14 inch Hybrid mattress Size: King
I’m picky. I will not sleep on an uncomfortable mattress. I recently bought a Serta-Simmons Beautyrest Silver BRS900 “Plush” King-sized mattress (They are no longer Simmons Beautyrest since they merged or got bought out). It seems since the merger they have completely destroyed the Beautyrest brand. I slept on Beautyrest mattresses for years that were very comfortable for the price. It seems that Serta-Simmons business practice is to make their entry level beds extremely uncomfortable, in order to steer customers towards paying thousands of dollars for one of their “Black Series” mattresses, which IMO are not even that comfortable. I personally tested out half a dozen Serta-Simmons Beautyrest Black series mattresses at mattress firm, and none of them were comfortable. The Silver line is just above their entry level mattress and cost me about $750 from Mattress Firm. That mattress was not remotely plush as it was advertised. It was firm. It was so uncomfortable that I started sleeping on my couch due to the severe hip pain it was causing me. I figured it was a long shot, but bought this mattress because many of the reviews described it as being “bouncy” and “soft”. The Serta-Simmons “Beautyrest” was definitely not bouncy or soft, it was stiff as a board. They should change their name to “Painfulrest”. The purveyors of Molblly should be proud of their product. I was prepared to be disappointed but they proved me wrong. This bed is very comfortable, and I can now sleep peacefully and wake up pain free*. Thank you Molblly, and for anyone considering buying a mattress, I highly recommend staying away from the Serta-Simmons Beautyrest brand, as since the merger between them and Serta (In my opinion Serta was always low-tier in terms of quality and comfort) their quality and comfort for the price has drastically been diminished. ... show more

  • It’s okay
Style: 14 inch Hybrid mattress Size: King
The price is great for a King size mattress. However, I do feel like it is a bit more on the firm side than soft. Also, if you sit on the edge of the mattress it sinks in so definitely avoid sitting on the edge of the mattress. Other than that, I don’t wake up with aches and pains so it does the job! I just hope it last a long time. ... show more
