Excellent product- All the reviews here are on point. Excellent product! Very soft and comfortable. Exactly what I was looking for. It folds perfectly and comes with a mattress protector. The foam is thick enough to offer a pleasant rest. I am very happy with my purchase and recommend it 100%. Review: Yep !!! The RV sofa has a new and better mattress - I bought this specifically to replace the spring mattress that came with our sofa bed in our 5th wheel. The queen size fits well and expanded to the full advertising size. The metal frame and bars are not a problem anymore. Originally I had put a 2” memory foam topper on the springs but have been unhappy with that setup as the metal frame was still a nuisance. Furthermore, the extra mattress thickness made folding the bed in a problem. This mattress fold in properly. I’m 74 and 6’4” 245 and while I do not intend to use this as a primary sleeper, I could, I believe, use this sofa in a pinch without a problem. My wife agrees that we made a wise choice in this mattress and she feels comfortable using it as a secondary bed. No complaints. Hope this helps someone in there decision ## Features - Our bi-layered mattress combines a 3in firm polyurethane foam base with a 1.5in soft memory foam topping that slowly conforms to your body contours and still provides adequate support that’s compatible with most folding couch bed frames and is also used for boat, camper & RV. - Rough night? Your mattress cover might be responsible. The jacquard waterproof soft cover included on our mattress is so soft and comfortable that you might skip the fitted sheets. It’s also ventilated to allow body heat to dissipate. Sleep soundly, not stifling. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08288L2BB | | Additional Features | Durable, Pressure Relief, Removable Cover | | Age Range Description | Adult | | Best Sellers Rank | #69,166 in Home & Kitchen ( See Top 100 in Home & Kitchen ) #224 in Mattresses #380 in Sofas & Couches | | Brand Name | Milliard | | Color | White | | Construction Type | Memory Foam | | Cover Material | Polyester | | Customer Reviews | 4.5 4.5 out of 5 stars (5,137) | | Fill Material | Memory Foam | | Is Customizable? | No | | Is Foldable | No | | Item Depth | 4.5 inches | | Item Dimensions | 73 x 52 x 4.5 inches | | Item Dimensions L x W x Thickness | 73"L x 52"W x 4.5"Th | | Item Firmness Description | Plush | | Manufacturer | Milliard | | Material Type | Memory Foam, Polyurethane | | Mattress Coil Type | Continuous Coil | | Mattress Comfort Layer Material | Memory foam | | Model Name | Memory | | Model Number | MIL-SFMT45 | | Number of Layers | 2 | | Product Benefits | Improves Sleep, Pressure Relief, Reduces Toss & Turn | | Product Care Instructions | Machine Wash | | Shape | Rectangular | | Size | Full | | Style Name | Modern | | UPC | 840985117900 | | top-style | Tight Top | ## Product Details - **Brand:** Milliard - **Color:** White - **Cover Material:** Polyester - **Fill Material:** Memory Foam - **Item Firmness Description:** Plush - **Number of Layers:** 2 - **Product Dimensions:** 73"L x 52"W x 4.5"Th - **Size:** Full - **Special Feature:** Durable, Pressure Relief, Removable Cover - **Top Style:** Tight Top ## Images ![Milliard 4.5 Inch Memory Foam Replacement Mattress with Breathable, Waterproof and Washable Cover for Full Size Sleeper Sofa and Couch Beds (Sofa Not Included) - Full - Image 1](https://m.media-amazon.com/images/I/51TRFwgINaL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Questions & Answers **Q: After opening the sleeper sofa, how long does it take for the queen size mattress to fully expand and be ready to sleep on?** A: It's packed in a vacuum sealed bag to make it smaller for easier shipping.

Hope this helps someone in there decision ### ⭐⭐⭐⭐ Measure your frame *by M***N on June 28, 2023* Measure your frame! We have a queen size and this mattress is too small -- I didn't measure my frame beforehand and trusted the "queen size" so I'm not deducting from the rating because that was my fault. This is just a word of caution to everyone else. Expensive mistake. That being said, it is significantly more comfortable than the mattress that came with the bed. I can feel where the bar is, but it is very minimal and so much better than before. I think this is a great purchase and it was worth the money. It is a tight squeeze to fold back up, but it does fold back up. ## Frequently Bought Together - Milliard 4.5 Inch Memory Foam Replacement Mattress with Breathable, Waterproof and Washable Cover for Full Size Sleeper Sofa and Couch Beds (Sofa Not Included) - Full - Heavy Duty Sleeper Sofa Support Board (48x48 - Full Size) Reinforced Wood Sofa Bed Support, Pull Out Couch Mattress Board, Sleeper Bar Shield, SleeperSaver by Meliusly - Sleep Philosophy Holden Waterproof Sofa Bed Mattress Protection Pad with 3M Scotchgard Moisture Management -Microfiber - All Over Elastic Mattress Pad, Full 54x72, White --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/185685881-milliard-4-5-inch-memory-foam-replacement-mattress-with-breathable](https://www.desertcart.co.uk/products/185685881-milliard-4-5-inch-memory-foam-replacement-mattress-with-breathable) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-15*
