The PlushBeds Slice Of Heaven Eco Green Sofa Mattress is a specialty product, not a bedroom mattress. It is a 4.5-inch latex insert designed to sit inside a sofa bed frame, and the official page states plainly that the sofa itself is not included. This review reads the documented specifications and policies as published by PlushBeds, then sets out who this product fits and who should look elsewhere. The short version: it is a credible choice if you need a replacement or upgrade for a sleeper sofa, and a poor choice if you want a primary bed.

What exactly is the Slice Of Heaven Eco Green Sofa Mattress?
It is a 4.5-inch sofa bed mattress insert built from natural latex with a CertiPUR-US certified Plushfoam support layer, sold without the sofa. The brand positions it as a folding insert that returns into the sofa frame while still supporting a 250 lb adult without metal bars pressing through. If you are shopping for a guest room bed, this is the wrong aisle entirely.
The construction, as described on the official product page, stacks an all-natural Sri Lankan botanical latex top layer with no fillers or blends over a proprietary soy-based Plushfoam base. PlushBeds states the foam base is what allows the mattress to fold back into the sofa. The cover is described as a certified organic cotton protective cover. The brand also states the latex is GOLS certified organic latex, the cotton is GOTS certified organic, and the Plushfoam layer is CertiPUR-US certified.
Three facts anchor the product page: 4.5 inches thick, support for a 250 lb adult, and a stated lifespan of up to 10 years. Those are the brand’s own published figures, and they are the right ones to weigh against your sofa frame’s depth and your household’s weight needs.
Who should buy the Slice Of Heaven, and who should not?
Buy it if you own a sleeper sofa and want a certified organic latex insert that replaces a thin, bar-imprinted factory mattress. The 4.5-inch profile, the stated 250 lb support rating, and the folding design address the exact complaints sofa sleepers raise. Skip it if you need a mattress for a bed frame, a platform bed, or any bedroom setup: at 4.5 inches this product is engineered to fold, and a folding insert is the wrong shape of solution for a stationary bed.
The second group to skip it: anyone who needs more than 4.5 inches of cushioning. Side sleepers with prominent shoulders and hips, and sleepers over 250 lb, should read the support claim carefully. The brand states the mattress supports a 250 lb adult comfortably; it does not publish a higher combined-sleeper rating on this page. If two adults share the sofa, check the total weight against that figure before ordering.
A third skip group: shoppers who want a long home trial. This product carries a 100-night return policy, and the brand states returns are refunded minus round trip shipping. That is a shorter window and a different cost structure than many bedroom mattress trials, so budget for the shipping deduction if you return it.
What sizes and prices does PlushBeds list?
PlushBeds lists three sizes with fixed prices: Twin at $629.00, Full at $804.00, and Queen at $874.00. The page also shows a promotional strike-through on the Twin, displaying $784.00 crossed out with $629.00 and a stated saving of $155.00. Pricing moves, so check the current price on the official site before you order.
| Size | Dimensions | Listed price |
|---|---|---|
| Twin | 35 in x 72 in | $629.00 |
| Full | 54 in x 72 in | $804.00 |
| Queen | 60 in x 72 in | $874.00 |
Measure your sofa bed’s open frame before choosing a size. The dimensions above are the mattress footprint, and a sofa bed frame that expects a narrower or shorter insert will not fold correctly with an oversized mattress. Free US shipping is listed, excluding Alaska and Hawaii.
How does the 4.5-inch latex build feel and support?
The documented build is a natural latex comfort layer over a soy-based Plushfoam base, totaling 4.5 inches. PlushBeds describes the airflow design as distributing body weight to reduce pressure points at the shoulders, hips, back, and knees. That is the brand’s stated intent for the surface, and it is a reasonable description of how a latex layer behaves over a supportive base.
The support claim is specific: enough support for a 250 lb adult to sleep without feeling metal bars. Sofa bed sleepers know that sensation, and the Plushfoam base is the component PlushBeds credits with both the folding function and the bar-buffering. The brand also states the latex is pure, with no fillers or blends, and emits no harmful gasses or odors.
Firmness is not published as a numbered scale for this model. If firmness matters to your purchase decision, compare it against a model with a published rating rather than guessing from the material description. For a sofa insert, the more useful question is thickness: 4.5 inches is what fits under a folding frame, and it is also what limits cushioning depth for sleepers who need more give.
Does it sleep cooler than a standard sofa mattress?
PlushBeds states the ventilation holes in the organic latex allow air to flow freely and draw heat away from the body. That is a construction claim about perforated latex, and it is the only cooling statement the brand makes for this product. Sofa sleepers often deal with trapped heat against a metal frame, so a perforated latex layer is a sensible design choice for that setting.
Buyers comparing cooling across products should check the official page for any updated wording, because cooling claims vary by model and by season of purchase. This matters most for people who sleep hot on sofa beds, since the frame itself restricts airflow underneath the mattress. Latex with open ventilation channels is a different proposition from the thin polyfoam pad most sleeper sofas ship with.
What do motion isolation, edge support, and noise look like?
The official page does not publish motion isolation, edge support, or noise figures for this model, so there is nothing to quote. When you evaluate those factors yourself, check the official product page for any updated specification and confirm how the insert sits inside your specific sofa frame. Edge behavior on a sofa bed is largely a function of the frame, not the mattress, so the frame’s rails matter as much as the latex.
These gaps matter most for couples sharing a sleeper sofa and for anyone sensitive to the creak of a folding mechanism. If either applies to you, read the current product page closely and consider the return terms before committing, since the 100-night policy deducts round trip shipping on returns.
What trial, warranty, and shipping terms are published?
PlushBeds publishes three clear terms for this product: a 100-night trial, a 10-year warranty, and free shipping within the US, excluding Alaska and Hawaii. The return policy states that if you are not satisfied within the first 100 nights from receiving your order, you can return the mattress for a complete refund minus round trip shipping.
- 100 nights from delivery to decide, with a full refund minus round trip shipping on return
- 10-year warranty as listed on the product page
- Free US shipping, excluding Alaska and Hawaii
- Latex stated to resist deterioration with a lifespan of up to 10 years
Read the written warranty and return terms on the official page before ordering, since policies change and the shipping deduction on returns is a real cost. The 100-night window is shorter than the 365-night trials many bedroom mattresses carry, which is worth noting if you tend to decide slowly.
How does it compare with a bedroom mattress like the Saatva Classic?
These are different products for different furniture. The Slice Of Heaven is a 4.5-inch folding latex insert for a sofa bed with a 100-night trial and a 10-year warranty. The Saatva Classic is a full-height innerspring bedroom mattress with a 365-night home trial, a lifetime warranty, free white-glove delivery with old-mattress removal, two heights, and three comfort levels. Choose based on the furniture you are furnishing, not on a feature list.
| Slice Of Heaven Sofa Mattress | Saatva Classic | |
|---|---|---|
| Product type | Sofa bed latex insert | Coil innerspring bedroom mattress |
| Height | 4.5 inches | 11.5 or 14.5 inches |
| Home trial | 100 nights, minus round trip shipping on return | 365-night home trial |
| Warranty | 10 years | Lifetime warranty |
| Delivery | Free US shipping, excluding AK and HI | Free white-glove delivery and setup, old-mattress removal |
| Comfort choices | Not published as a scale | Plush Soft, Luxury Firm, Firm |
If your sofa bed is the purchase, the Slice Of Heaven is the relevant product and the Classic is irrelevant. If you are furnishing a bedroom, the reverse is true.

World Sleep Almanac score: 7.4/10. Our editorial score is based on five criteria: price at equal size, trial and return terms, warranty length, materials and construction, and publicly stated certifications. The Slice Of Heaven scores well on materials (GOLS organic latex, GOTS organic cotton, CertiPUR-US foam) and on a clearly published 10-year warranty, but loses points on the 100-night trial with a round trip shipping deduction and on the narrow use case that limits who it serves. The score is editorial, not a lab result, and reflects the documented facts on the official page at the time of writing.
Verdict
Buy the Slice Of Heaven if you need a certified latex insert for a sleeper sofa and your frame takes a 4.5-inch mattress. Skip it if you need a bedroom mattress, if you sleep over 250 lb, or if you want a trial longer than 100 nights with no shipping deduction.
