Additionally, the SG1 LTM surface eliminates disruption of the other sleeper when one gets out of bed and with varying weights of sleep partners. NASA astronaut training is often done under water as it simulates the effects of being weightless because the human body, comprised of 90-percent water, is in balance with the fluid environment. Just as babies are suspended in a gravity neutral fluid environment until born, InnoMax SG1 Hydrodynamic Sleep mattresses truly offer flotation support as nature prescribes. The body can only be truly relaxed when muscles do not have to constantly fight the forces of gravity. SG1 fluid suspension evenly supports your body in gravity neutral sleep and offer hygienic environment as they are easily cleaned with approved Waterbed Vinyl Conditioner. Review: The best sleep ever! - Bed technology is such BS. We went on a 10 year quest to figure out the most important 8 hours of every day of your life...fact: it's a waterbed. My wife and I tried high quality mattresses for $5k, Costco mattresses at $1K, sleep number at $3K, memory foam for $4K, organic latex for $2K, even the Dux feather bed for $10K! Returned them all within the return period. The winner: 1970's style waterbed! We found a great frame and headboard online for $500, use a $100 heater, a thick quality mattress pad, the best safety liner for another $50, and water conditioner for another $10/year. Every night when you slip into bed the first thing you feel is warmth and snuggles. Then the fun giggling of water motion like you are playing in the pool. Supports your back, great for your neck (use a very soft pillow) and, of course, it's great for your love life! Of the things a modern human needs, access to healthcare, government stability, a Toto Washlet, and the best nights sleep possible. Now, I get that some rentals or multi-family do not allow them...that is what the safety liner is for. In 15 years we have had 2 failures. They do not POP...they seap. So if you have a leak, usually in a seam, you wake up to a little wettness. You simply drain it into the bathtub and get a new mattress and liner for $150. Not bad! Considering how much a conventional mattress costs. A month ago, we woke up to our 2nd failure in many years. It looks like it may have been seaping for a few days...the mattress pad and sheets soaked up the majority and nothing escaped the safety liner. I drained it...3 days later, thanks to desertcart, we are back to bed. Thanking the Maker we had our waterbed back. (This time, as an extra caution, I added one of those $20 water leak detectors for early warning.) Seriously, I can not tell you how much more luxurious and restorative sleeping in a warm waterbed can be. Review: GREAT BUY IF ... - We decided to replace our old mattress after 30+ years of use and purchased the Innomax Sanctuary SGL mattress. When you do something once every 30 years, you tend to forget construction details that can cause grief if not attended to :0). So, we slowly pumped the mattress up with air and let it set for a week to check for leaks and let the vinyl offgas chlorine. A week later it was still holding pressure and didn't hardly smell so it was installed and has worked fine. Build quality is good. We will be careful with the fill cap pull tabs to ensure we don't break them. All in all if you are willing to do some checkout before installation, you should avoid any pitfalls. Just remember that when you compare the Innomax pricing with a conventional mattress, you can buy many waterbed mattresses for the price of just one conventional. So, if things don't work out and you don't like the warranty conditions, just buy another mattress from a vendor of your choice :0). ## Features - Sanctuary Free Flow Deep Fill Waterbed Mattress for full depth rigid side box frame Full Wave Performance and 20 year warranty - No Wave Reduction and weightless feel featuring Full Motion Performance and gravity neutral fluid suspension mid-body support - Zero wave elimination system and 20 mil premium vinyl Body Profile sleep surface generously overcut Low Tension Mattress design - Double Reinforced Corners and T-Corner Lap Seam Construction - Use with approved Waterbed Heater Waterbed Safety Liner Waterbed Water and Vinyl Conditioner Do Not Fill above Safety Liner ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00ARV4MZG | | Additional Features | Pressure Relief | | Age Range Description | Adult | | Best Sellers Rank | #1,281,975 in Home & Kitchen ( See Top 100 in Home & Kitchen ) #33 in Waterbed Mattresses | | Brand | INNOMAX | | Brand Name | INNOMAX | | Color | Wine | | Construction Type | waterbed | | Cover Material | Vinyl | | Customer Reviews | 4.6 out of 5 stars 408 Reviews | | Fill Material | Water | | Global Trade Identification Number | 00819593010170 | | Is Customizable? | No | | Is Electric | No | | Is Foldable | No | | Item Depth | deep fill | | Item Dimensions | 84 x 72 x 9 inches | | Item Dimensions L x W x Thickness | 84"L x 72"W x 9"Th | | Item Firmness Description | Firm | | Item Type Name | Mattress | | Item Weight | 11.7 Pounds | | Manufacturer | InnoMax Corp. | | Manufacturer Part Number | 1-05-FF-01 | | Manufacturer Warranty Description | 20 year limited warranty. | | Material Type | Vinyl | | Mattress Coil Type | Pocketed Coil | | Model Name | Sanctuary Free Flow | | Model Number | 1-05-FF-01 | | Number of Layers | 1 | | Portable | No | | Product Benefits | Custom tailored hydrodynamic sleep, weightless support, zero wave elimination, reinforced corners, hygienic surface, reduced sleep partner disruption | | Product Dimensions | 84"L x 72"W x 9"Th | | Size | King | | Style Name | Modern/Contemporary | | Top Style | Tight Top" or "Euro Top | | UPC | 819593010170 | | Unit Count | 1.0 Count | | top-style | Tight Top" or "Euro Top | ## Product Details - **Brand:** InnoMax - **Size:** King - **Product Dimensions:** 84"L x 72"W x 9"Th - **Top Style:** Tight Top" or "Euro Top - **Cover Material:** Vinyl - **Number of Layers:** 1 - **Special Feature:** Pressure Relief - **Color:** Wine - **Model Name:** Sanctuary Free Flow - **Construction Type:** waterbed ## Images ![InnoMax Sanctuary Free Flow Watermattress - Image 1](https://m.media-amazon.com/images/I/51FXIcm80tL.jpg) ![InnoMax Sanctuary Free Flow Watermattress - Image 2](https://m.media-amazon.com/images/I/51ZHl0zdDUL.jpg) ![InnoMax Sanctuary Free Flow Watermattress - Image 3](https://m.media-amazon.com/images/I/71VD871ERLL.jpg) ![InnoMax Sanctuary Free Flow Watermattress - Image 4](https://m.media-amazon.com/images/I/71+nPiljbUL.jpg) ![InnoMax Sanctuary Free Flow Watermattress - Image 5](https://m.media-amazon.com/images/I/616-TjaC2GL.jpg) ## Questions & Answers **Q: How much water does this king-sized mattress hold?** A: 7ft x 6ft x 0.75ft = 31.5ft³; 1ft³ = 7.4805 gal 31.5x7.48= 235 gallons of water this mattress can hold. 1gal H20 = apx. 8.34lbs; 235x8.34=1,959.9lbs of water. Also take into consideration the weight of beadframe/headboard while purchasing plywood and building boxframe (as I am) **Q: How thick is the vinyl? Specifically... in mils ?** A: 18 Mil **Q: Where can you get a waterbed frame** A: I found my king size water bed frame on Craigslist but if you don't want to go that route there are online stores that you can buy the frames from **Q: Is this for the softside waterbed? I think i ordered the wrong thing** A: I don't think so I have a wooden frame for my waterbed and this mattress fits inside a liner. I don't think it would work without something to support it ## Customer Reviews ### ⭐⭐⭐⭐⭐ The best sleep ever! *by F***A on October 14, 2023* Bed technology is such BS.

This mattress was delivered and was quickly removed from packing by me expecting this horrible smell everyone was mentioning? While there was some no where near as much as the complaints, it is a large plastic bladder that is brand new what was everyone expecting, Geez. Set mattress up quickly in frame and started to fill. Here was another knock fill area in middle? Again its not in the middle of the bed its at the bottom of the bed in the middle and doesn't get in the way of anything in fact it was much easier than my last mattress to fill. Filled it to my preferred way and turned heater on. While it is recommended to wait 24 hours to sleep on I was able to use it that night and Slept GREAT! Way smoother than last mattress, heated nicely and quickly. Have used this mattress for a few weeks now and am extremely satisfied and there is no smell at all. If you want a great mattress on a budget this is perfect. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ie/products/1474923-innomax-sanctuary-free-flow-watermattress](https://www.desertcart.ie/products/1474923-innomax-sanctuary-free-flow-watermattress) --- *Product available on Desertcart Ireland* *Store origin: IE* *Last updated: 2026-06-06*
