Ideal for millennials seeking a blend of nostalgic comfort and modern quality, this mattress balances gentle movement with body-leveling support for a uniquely restful sleep experience. ## Description If you are replacing a super single waterbed mattress also known as a California twin then this mattress is an excellent choice. This 90% Semi waveless mattress is very comfortable and popular because it has 4 layers of super soft fiber running from head to foot along with an extra double layer of contour fiber in the mid section which will help your body sink into the mattress more level. It has about 5-7 seconds of movement which is less movement than a free flow, 1 layer or 2 layer mattresses. So it still has some movement plus it contours more to your body and the contour fiber in the mid section will help your body level you off. This mattress is made in the U.S. and it is made with quality vinyl and reinforced corners. Most super single mattresses by other brands are imported from China. Not this one. This mattress measures 48 inches wide by 84 inches long and 9 inches deep. This is the standard inside measurement for super single hardside waterbeds . If you have any questions feel free to email.

I carried and sold Land & Sky because they were the better quality manufacturer back in the 80s & 90s and I'll have to say I took a chance when going with this manufacturer and to date am very pleased with it. It seems to be made of high quality vinyl and the fiber fill (for motion reduction) seems to be of high quality too. The mattress does come vacuumed seal just as a reassurance that there are no pin holes or seams that aren't sealed so when you open it you can feel safe before filling it. Something many people don't do after filling their bed is to remember to add waterbed conditioner to the mattress on regular intervals as recommended...THIS IS THE LIFE OF YOUR WATERBED MATTRESS!! I cant' emphasize this enough, don't use bleach on anything like that, a good quality waterbed conditioner is well worth the cost to give you long life and service out of your waterbed mattress!! Review: So far so good - I generally get 12-14 years out of a mattress, I did have to buy one twice as the corner seam leaked and it was less than a year old. So far so good with the replacement. ## Features - Perfect replacement mattress for super single hardside style waterbeds.This mattress is rated at about 90% Waveless and it has fiber in the mid section which will help keep your body more level. This comfortable water mattress has about 5-6 seconds of movement. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004U3CU0G | | Age Range Description | Adult | | Best Sellers Rank | #1,316,009 in Home & Kitchen ( See Top 100 in Home & Kitchen ) #40 in Waterbed Mattresses | | Brand | U.S. Water | | Brand Name | U.S. Water | | Closure Type | Pull On | | Color | Charcoal Gray | | Customer Reviews | 4.3 out of 5 stars 24 Reviews | | Included Components | 4 layers of super soft fiber, extra double layer of contour fiber | | Item Display Dimensions | 84 x 48 x 9 inches | | Manufacturer | U.S. Water | | Manufacturer Part Number | Super_Single_90%_Waveless | | Manufacturer Warranty Description | 12 years prorated warranty. | | Material Type | Vinyl | | Model Number | SS4000L | | Other Special Features of the Product | Washable | | Product Care Instructions | Hand Wash Only | | Size | Super Single, 48 x 84 | | Special Feature | Washable | | Unit Count | 1 Count | | Water Resistance Level | Water Resistant | ## Product Details - **Brand:** U.S. Water - **Closure Type:** Pull On - **Color:** Charcoal Gray - **Size:** Super Single, 48 x 84 - **Special Feature:** Washable ## Images ![Super Single 90% Waveless Waterbed Mattress - Image 1](https://m.media-amazon.com/images/I/61mnrWKm1nL.jpg) ## Questions & Answers **Q: what mil (thickness) is the material? Is it vinyl? if not - please let me know what the mattress is made of.** A: I don't know the exact thickness of the mattress material. The mattress is very well made of a heavy vinyl material. **Q: Do I need a special bed frame for this mattress? Will a single size hospital bed frame work?** A: Water bed sizes are different than non water bed sizes so yes you need a special waterbed frame. Also you need a bed frame in which you can put a liner in case you puncture the mattress **Q: Will this mattress fit a dual california king waterbed? I just need one side replaced.** A: The Super Single waterbed mattress is 48 inches by 84 inches. **Q: How much does this super single mattress weigh when filled with water?** A: Around 1350 lbs. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very pleased!! *by M***. on April 13, 2021* I owned and sold waterbeds for 10 years so I have a little experience with waterbed mattresses.

So far so good with the replacement. ### ⭐⭐⭐⭐⭐ Love it *by D***E on November 4, 2022* My old waterbed internals came apart, 25 years old. Then a random leak, caused me to look for a replacement. The support, this one offered, made me choose it. Had a leak on one of the caps, but was easily solved with sulephane(cling-wrap). ## Frequently Bought Together - U.S. Water Super Single 90% Waveless Waterbed Mattress - Blue Magic All Purpose Waterbed Conditioner, 8 fl oz (237 ml) --- ## 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.pt/products/6462716-super-single-90-waveless-waterbed-mattress](https://www.desertcart.pt/products/6462716-super-single-90-waveless-waterbed-mattress) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-10-21*
