Description

1.How firm is this mattress? Balanced comfort; firmness varies by weight and sleep style. Under 130 lb may feel firmer; 130–230 lb get cushioning; over 230 lb feel contouring. Back sleepers notice even alignment, side sleepers more cushioning, stomach sleepers flatter. 2.Which thickness should I choose — 10", 12", or 14"? It depends on how you’ll use the mattress. 10" suits guest rooms, dorms, small spaces or budgets. 12" is most popular for daily sleep and couples. 14" feels premium with extra cushioning for bedrooms or adjustable frames. Unsure? Most start with 12". 3.What type of bed frames does this mattress work with? This mattress is compatible with platform beds, slatted frames with proper spacing, adjustable bed frames, and solid foundations. 4.How long does a foam mattress usually last, and when should I replace it or add a topper? Most quality foam mattresses on a supportive frame stay comfortable 7–10 years, depending on use and body weight. If it feels supportive but less plush, a 2–3 inch topper can refresh the surface. Deep sagging or uneven support means replacement. 5.How long does it take to fully expand after opening? Most mattresses fully expand within 2-12 hours.Cold weather can slow expansion, so let the sealed box warm indoors before opening. After unboxing, ventilate the room and allow extra time for foam to regain its shape and feel.

Overall, I’m happy with it and think it’s a good mattress for the price!
I’m really happy with this 12-inch firm twin memory foam mattress. Just feeling it with your hand, it feels soft and comfortable, but once you actually lay down on it, it feels much firmer. I think it definitely needs some time to break in and soften up. It has good support and a nice thick feel. Overall, I’m happy with it and think it’s a good mattress for the price! ... show more

Absolutely the best firm mattress
Color: White & Black Size: King Set name: 14" Luxe Extra Firm
If you looking for a firm mattress but still comfortable that’s your mattress. We spend almost $5000 for a temper pedic almost 2 years ago and was a waste of money. For $500 so far so good👍🏼 I don’t even wake-up to go to the bathroom. I highly recommend! Gia-Ct

Nice firmness
Color: White & Black Size: King Set name: 12" Luxe Firm
At first I was thinking it was not as firm as I wanted it to be but I let it sit for the 3 full days without jumping into it and yes! It’s a nice firm mattress as advertised now I just need to find a pillow that works. But I’m very happy with my purchase it’s only been a couple of weeks but so far so good ... show more

Get it you won't be disappointed
Color: White & Black Size: King Set name: 12" Luxe Extra Firm
I have been looking for a firm mattress for 6 months and was reading the reviews before deciding to purchase one. I almost didn't get this one because someone said they didn't think it was firm enough. Let me tell you that this mattress is very firm. My back and hip pain are gone. I absolutely love this mattress. I put a thin topper on it and sleep like a baby. We let it inflate during the day and slept on it that night. The quality it great and the support it unbelievable awesome. ... show more

Affordable and recommended!
It’s very good quality. I was having bad back issues from my old mattress. This has helped heal my back pain over time. Slept very comfortably. I would recommend this affordable mattress to anyone.

Extra firm means extra firm!
Color: White & Black Size: Queen Set name: 14" Luxe Extra Firm
They weren’t kidding when they said extra firm. This mattress is unyielding. It turns out to be too hard for me but I will invest in a softer mattress topper soon. Does not retain body heat but not sure how that will work if I add a soft mattress topper. Great height of 14” though. Easy to open and install. Well worth the cost. ... show more
