Waterbed Doctor Mattress Review

Waterbed Doctor is the house brand of The Waterbed Doctor, a waterbed specialist in Westminster, California (Simplex International Inc.). It has sold direct online since 1999. The hardside wood-frame waterbed mattresses covered here cost $149.95 to $535.95. They come with free lower-48 shipping, 30-day returns and a free 20-year extended warranty. You're buying only the mattress, not a bed. If you own a hardside waterbed and need a new vinyl bladder, it's a value pick. If you want foam, hybrid or innerspring, look elsewhere.

Match by motion preference first. For full water motion, pick the 9200 RXE (0 percent waveless, 6 to 8 seconds). For a little wave reduction, pick the 9251 RXE (60 to 65 percent). For a soft semi-waveless feel, pick one of three. The RX 9306 is 80 to 85 percent, super soft, with no lumbar. The 300 RX Plus is 85 to 90 percent with mild lumbar. The 9256 RXE is 85 to 90 percent with 2 lumbar layers.

For very little motion, pick the RX 9756 (90 to 95 percent, semi firm, no lumbar) or the 400 RX Plus (90 to 95 percent with medium firm back support). For near-zero motion, pick the 600 RX Plus or RX 9876 (95 to 99 percent, with lumbar and edge support). The 700 RX Plus is 99 to 100 percent, firmest, with extra back support.

If you want back support, favor the RX Plus line with foam lumbar layers. For an easier exit, favor the 600 RX Plus, 700 RX Plus or RX 9876 edge support. Budget side sleepers who want a soft water feel can look at the 300 RX Plus. No model has cooling features. The brand doesn't publish per-weight guidance or durability testing (checked September 2026). The 24 mil RX Plus vinyl is the thickest offered.

These are sale prices on the official site as of September 2026. The 9200 RXE is $149.95, 9251 RXE $212.95, RX 9306 $309.95, 9256 RXE $359.95, 300 RX Plus $409.95, RX 9756 $419.95, RX 9876 $465.95, 400 RX Plus $469.95, 600 RX Plus $479.95 and 700 RX Plus $535.95. Compare-at prices are $189.95, $269.95, $337.95, $391.95, $419.95, $439.95, $510.95, $515.95, $536.95 and $588.95. That's roughly $10 to $57 off each model.

Shipping is free to the lower 48 states. Faster 1 to 2 day or 2 to 3 day options add roughly $89 to $240, depending on model. By model, expedited shipping adds these amounts. The 9200 RXE is $99 to $119. The 9251 RXE is $98 to $126. The RX 9306 is $89 to $109. The 9256 RXE, RX 9756 and RX 9876 are $156 to $196. The 300 RX Plus is $138 to $182. The 400 RX Plus is $158 to $220. The 600 and 700 RX Plus are $198 to $240. These house-brand hardside mattresses are the cheapest way into this store's waterbed line. The same site sells softside Flotation Sleep systems from $764.95 to $1,974.95, plus third-party waterbed brands at their own prices.

The brand doesn't publish financing, sales tax notes or price-match terms (checked September 2026). Under $550 with a free 20-year extended warranty is strong value for a waterbed replacement bladder. But you're buying only the mattress. Water, heater, frame and conditioner are separate.

Every model is a vinyl water mattress that you fill with water. The 9200 RXE uses 18 mil smooth vinyl. The 9251, 9256, RX 9306, RX 9756 and RX 9876 use 20 mil smooth vinyl. The 300, 400, 600 and 700 RX Plus use 24 mil premium smooth vinyl.

Layers of fiber make the bed waveless. The 9200 RXE has none, the 9251 RXE has 1 layer and the RX 9306 has 2. The 300 RX Plus has 3 plus 2 mid-section layers, the 9256 RXE has 4 plus 2, and the 400 RX Plus has 4 plus 3. The 600 RX Plus has 4 plus 4 inch blue progressive foam. The RX 9756 has 5, and the 700 RX Plus has 5 plus 4 inch blue progressive foam. The RX 9876 has 4 plus 3 inch blue progressive foam.

The fiber is anchored in 4 corners so it won't shift, and each mattress has a built-in thermometer. The site states Made in the USA. The product page for the 300 RX Plus is detail.aspx?ID=4871. The brand doesn't publish foam certifications such as CertiPUR or OEKO-TEX, or PVC-free or phthalate claims (checked September 2026).

The brand backs durability with vinyl thickness, fiber anchoring and warranty length, not independent tests. The 24 mil RX Plus models carry 7-year free replacement. The 20 mil RX models get 5 years, the 20 mil 9251 and 9256 RXE get 4 years, and the 18 mil 9200 RXE gets 3 years. All sit inside a free 20-year extended warranty.

The site calls the RX Plus line extra premium with the best fiber in the industry. The softside pages claim three times the comfortable product life for removable tops. The brand doesn't publish lab fatigue, ILD or burst-test data (checked September 2026). The FAQ says to use waterbed conditioner every 8 to 18 months. It says never turn the heater off except when draining, and watch for condensation that can lead to mold. If you must store a drained mattress, fold it in a cardboard box at room temperature.

The Waterbed Doctor (Simplex International Inc.) is a BBB Accredited Business with an A+ rating. It's been accredited since 10/13/2003. The business started 11/4/1999 and was incorporated 1/30/2007. The owner is Martin David Pojar, and an archived profile lists 25 years in business. That archived profile shows no customer reviews and no complaints as of 2025.

Sitejabber shows a single review, 3.5 stars (September 14, 2013), from a California customer. They were glad to find a store that still carries waterbeds and frames, and said the replacement bed is even better than before. We found no Yelp rating, Google score, Trustpilot page, ResellerRatings page, Amazon listing or on-site star ratings (checked September 2026). Treat BBB accreditation and the long warranty as the main trust signals. You won't find a crowd of verified reviews.

Buy from the official online store at thewaterbeddoctor.com, or visit the one showroom at 15132 Goldenwest Circle, Westminster, CA 92683. The phone is 1-800-420-2337, international 714-893-5351, and fax 714-890-1426. The site footer lists Monday to Friday 9:00 A.M. to 5:00 P.M., Saturday by appointment and Sunday closed. The contact page lists Monday to Friday 8:30 A.M. to 5:00 P.M. and Saturday by appointment.

The company also runs Advanced Sleep Comfort (advancedsleepcomfort.com), Advanced Bedding (advancedbedding.com) and a Facebook page. The brand doesn't publish any other dealer network (checked September 2026). Most buyers order online or by phone, and the store ships worldwide.

Shipping is free to the lower 48 states. Alaska, Hawaii and international orders get quotes after you order, and you can decline. Replacement waterbed mattresses ship as small items by UPS or FedEx. The brand says same-day shipping, with delivery in 1 to 5 days, weather permitting. Credit card orders ship within 24 hours unless out of stock. E-check orders are delayed 5 to 7 days. Paid upgrades promise arrival in 1 to 2 days or 2 to 3 days for roughly $89 to $240 extra.

Complete beds, airbeds and bedroom furniture ship by freight and arrive in 2 to 3 weeks. The trucking company calls to schedule a weekday delivery. Furniture has free curbside delivery, or garage or carport delivery for about $100 to $200 extra. Mattresses are do-it-yourself fill-and-drain jobs, and the FAQ explains filling, draining and packing. Bed assembly instructions can be downloaded. The brand doesn't publish a white-glove setup service or old-mattress haul-away (checked September 2026). The return policy says the company doesn't pick up products in a return.

You get a 30-day return policy from the day you receive the product, with no restocking fee. If you return something, you pay return shipping. The original outbound shipping cost comes out of your refund, even if the order showed free shipping. One exception applies to waterbed mattresses. If you filled it and find it uncomfortable, you can exchange it once within 30 days for a mattress of equal or greater value. You pay the difference plus the shipping on the second mattress.

Used items, electric waterbed pumps (exchanged under warranty only) and used or laundered mattress pads and sheets can't be returned. Send returns in the original boxes by UPS or FedEx, with tracking and enough insurance, to the Westminster, CA warehouse. You bear the risk of a lost package. A softside waterbed with a 30 Day Trial keeps all other terms. The brand doesn't publish a night-count trial for hardside mattresses beyond this 30-day window. The Waterbed Doctor Comfort Guarantee is named on product pages, but the brand doesn't publish its full terms (checked September 2026).

All 10 models carry a free extended 20-year warranty, which the site calls Best in The Industry. The free-replacement window varies. It's 7 years on the 300, 400, 600 and 700 RX Plus (24 mil vinyl). It's 5 years on the RX 9106, RX 9306, RX 9756 and RX 9876 (20 mil vinyl). It's 4 years on the 9251, 9252, 9253, 9254 and 9256 RXE (20 mil vinyl). It's 3 years on the 9200 RXE (18 mil vinyl). Electric waterbed pumps are warranty exchanges only.

The brand doesn't publish a full warranty document, exclusions, proration schedule, shipping responsibility or claims process (checked September 2026). One warranty page link returns an error. Ask for written terms before you order. Read the 20-year figure as an extended warranty wrapped around a shorter free-replacement period.

This is a waterbed niche brand, not a conventional mattress maker. Within waterbed retail, its comparison set is the other lines the same store carries. They are American National, Boyd, Comfort Craft, Genesis, Land and Sky, Somma, Sterling and Strobel, plus Watercloud softside replacement parts. Waterbed Doctor is the house brand with value prices ($149.95 to $535.95) and the longest free-replacement terms, up to 7 years.

Against mainstream brands such as Sealy, Tempur-Pedic, Sleep Number and online foam brands, it's category versus category. A waterbed gives full-body flotation, adjustable warmth, and near-zero or full motion by model. Mainstream beds offer sleep trials, showrooms, app features and easy returns. None of that is matched here beyond a 30-day policy and one California showroom. We found no head-to-head testing or awards, and mainstream review outlets don't appear to cover the line (checked September 2026).

We read the brand's own product, policy and warranty pages, then checked retailer listings and public complaint sites like the Better Business Bureau. We last checked everything here in September 2026. Prices and policies change, so confirm them on the seller's page before you buy. You can read more in our methodology and editorial policy.
