These three are all-foam beds that arrive compressed. A single ASIN was not pinned for this guide, so each button opens an Amazon search. The grade reflects that. Spec scores stay modest when several listings share a brand name, and the review score stays low when comments cannot be tied to one model.
Match the title before the photo
The words that matter are the brand, the size, the height, and the line name. EGOHOME, king, and 14-inch belong together. Nectar, queen, and 12-inch belong together, and you still have to separate the Classic from thicker Premier or luxury versions. Novilla, Bliss, queen, and 12-inch belong together. A different height under the same brand is a different bed.
Foam isolates motion because it is one slab, not a row of tied coils. It also holds heat. Gel in the comfort layer and a knit cover slow the warmup. They do not turn memory foam into a cool surface. If you sleep hot, that limit belongs in the decision next to the letter grade.
Firmness is a word, then a few weeks of foam
Nectar describes the Classic as firm, which is a reasonable place to start for stomach sleepers and lighter back sleepers. Many Bliss listings describe a medium feel. EGOHOME’s current 14-inch descriptions center on a gel memory-foam comfort layer, and the exact stack changes by listing, which is why this page does not freeze layer thicknesses.
Foam relaxes after you unbox it. The feel in week one is not the feel in week six. Give the room air while that happens. A new foam bed often has a factory smell that fades as it off-gasses. CertiPUR-US shows up on many of these listings and is worth confirming on the page you buy if low-emission foam is one of your requirements. The badge applies to the foam standard, and a missing badge on one seller’s photos is a reason to keep looking.
Returns, weight, and the staircase
A queen or king of this thickness is heavy once it expands. Plan on two people for the stairs. Measure the turn at the landing against the box, not against the expanded mattress. The box is the thing that has to reach the room.
Amazon’s return window and a brand-site trial are separate offers. Read who pays the return freight before you rely on a long trial. Pressure-relief and pain-relief lines on a listing are the brand’s marketing. This guide has not laid on these mattresses, and a grade here is not a medical claim.
Hybrids with coils, latex beds, and adjustable bases are outside this roundup. They solve edge support and airflow differently, and they deserve their own comparison once the listings are as specific as these three searches.
Product notes
Each note explains the letter with the three rubric scores. Specs are manufacturer or listing figures. Review points are themes, not a star average.
EGOHOME
EGOHOME King 14-inch Memory Foam Mattress
Specs 2/3Value 2/3Reviews 1/3
A 14-inch all-foam king sold as a bed-in-a-box. Current EGOHOME descriptions use a gel memory-foam comfort layer. Search results include more than one 14-inch king, so the layer diagram on the listing is the thing to match.
Why this grade. Height, size, and an all-foam construction are clear, and the layer stack changes across listings that share the EGOHOME name. It sits in the tall-foam king tier. Review themes cannot be tied to one listing, so sentiment stays at 1.
- Size in this guide
- King
- Height
- 14 inches
- Type
- All-foam memory foam, compressed in a box
- Comfort layer
- Gel memory foam on current EGOHOME descriptions
- Foundation
- Platform or slats, per the listing you open
Pros
- Fourteen inches is a tall foam stack, with more material between you and the slats than a 12-inch bed.
- A solid foam slab isolates motion from a partner rolling over.
- It ships compressed. The hallway sees a box, not a floppy king.
- King is the right search when two adults want width. A queen listing is a different product.
Cons
- Memory foam holds heat. Gel and a cooling-style cover slow the warmup.
- Foam edges compress when you sit on the side of the bed.
- Amazon's return window and a brand-site trial are different policies. Read who pays the return freight.
- Several EGOHOME kings share a height. Open the layer list before you add it to the cart.

Nectar
Nectar 12-inch Queen Mattress
Specs 2/3Value 2/3Reviews 2/3
Nectar's 12-inch queen is the familiar all-foam bed-in-a-box in this guide. Nectar describes the Classic feel as firm, with gel memory foam in the comfort system. Confirm you are looking at the 12-inch queen, not a Premier or a luxury thickness.
Why this grade. The 12-inch queen and Nectar's firm Classic description are stable, with thicker Nectar models easy to mix in. It is a known brand tier above budget foam. Public review themes cluster on firmness and heat, which matches that description.
- Size in this guide
- Queen
- Height
- 12 inches
- Feel
- Firm, in Nectar's Classic language
- Type
- All-foam, gel memory foam comfort layer
- Setup
- Unbox in the room and let it expand
Pros
- A firm foam queen is a common starting point for stomach sleepers and lighter back sleepers.
- Nectar listings are easy to compare because the brand has a long public paper trail.
- Queen fits the frames most bedrooms already have.
- Foam construction keeps motion on one side of the bed.
Cons
- Firmness shifts as the foam relaxes in the first weeks. The word on the title is a starting hint.
- A 12-inch queen is heavy once it expands. Plan on two people for the stairs.
- Nectar sells several thicknesses. The search can mix Classic with thicker models.
- Pressure-relief language on the listing is the brand's. This site has not laid on the mattress.

Novilla
Novilla Bliss Queen 12-inch Mattress
Specs 1/3Value 3/3Reviews 1/3
Novilla's Bliss is the budget-positioned 12-inch queen in this comparison. Listings describe a gel memory-foam bed-in-a-box, often with a medium feel. Confirm the height and the Bliss name, because Novilla sells other thicknesses.
Why this grade. Bliss, queen, and 12 inches are the match point, and layer densities are not stable enough to freeze. The value score is for a budget foam queen with no membership and no proprietary detergent. Sentiment stays at 1 until one listing is pinned.
- Size in this guide
- Queen
- Height
- 12 inches
- Type
- Gel memory foam, bed-in-a-box
- Feel
- Often described as medium on Bliss listings
- Cover
- Knit cover
Pros
- Same basic setup as the other two: compressed foam, a platform or slats, no traditional box spring required if the listing agrees.
- Twelve inches makes the height easy to compare with the Nectar queen.
- Novilla is the budget-positioned brand here. Compare the live price on Amazon. This page does not print one.
- A medium description is a different bet than Nectar's firm Classic.
Cons
- Lower-priced foam often uses a less dense base. Heavier sleepers should read the weight line on the listing.
- A cooling-style cover is a surface treatment. The foam underneath still holds heat.
- The trial and warranty on Amazon can be shorter than the brand's own website.
- Novilla sells more than one height. Bliss, 12-inch, and Queen belong together in the title.

Questions
Does a higher mattress mean a softer mattress?
Height is the stack of foam. Firmness is how that foam feels. EGOHOME's 14-inch king is taller than Nectar's 12-inch queen. Nectar still describes the Classic as firm. Read the feel word and the layer list on the listing you open.
Is the trial on Amazon the same as the brand's website?
Often it is a different policy. Read the return window, the trial length, and who pays freight on the Amazon listing itself. A 365-night promise on a brand site does not automatically transfer to a marketplace seller.
What foundation do these foam beds need?
A platform or a slatted base is the usual match, with gaps narrow enough that the foam is supported. Confirm the listing's foundation rules, and measure doorways before delivery day. The box is smaller than the expanded mattress.
