Choose the mattress and moving base as a compatible pair. Check whether both sides move together or separately, what the weight limit includes, and how much room the moving sections need. Controls, installation and support after purchase matter as much as the frame’s appearance. Structural components: articulating platform sections, electric linear actuators or manual ratchets, remote or app controls, support frame and legs.

Describe the movement you want when speaking to the supplier. For specialist care needs, ask a qualified professional to help select suitable equipment. ## Match the mattress to the base A mattress must bend where the base bends and tolerate that movement in normal use. Ask for compatibility in writing for both model names. The material label is not enough: two pocket-sprung mattresses may have different borders, depths and approved uses. Check width and length in centimetres. A nominal king-size arrangement can contain two narrow mattresses, and those individual sizes may differ from an ordinary UK single. Record the dimensions of each half and check fitted sheets before ordering. For independent movement, use the configuration the manufacturer specifies. Do not assume you can zip together two ordinary mattresses and then raise one half. Ask whether synchronised operation is possible when you want both sides level. ## Read the weight limit carefully There is no universal adjustable-bed capacity. A label may describe user weight, total working load, or the load allowed on one base section. Those figures are not interchangeable. Ask the supplier to confirm: 1. Whether the mattress and bedding count towards the stated limit. 2. Whether the figure applies to each side or the complete bed. 3. Whether the limit covers movement as well as lying flat. 4. Whether sitting on the edge has separate restrictions. Save the answer with the manual. A heavier replacement mattress may change whether the complete setup remains within its approved limit. ## Check the room, power and controls Measure the full frame, not just the mattress. Request a drawing showing the clearance needed while sections move. Check the headboard, wall, bedside furniture and bedding at the foot end. Keep the space beneath moving parts clear. Locate the power socket and follow the instructions for cable routing. Ask what happens during a power cut and how the base returns to flat. Do not assume every model has battery backup or an emergency-lowering system. Try the remote before purchase where possible. Check that you can identify and operate its buttons easily. Ask whether essential functions work without a phone app, how paired remotes are identified, and how replacement controls are obtained. ## Plan installation and support Confirm who brings the parts upstairs, assembles the bed and demonstrates its use. Give the installer your access measurements in advance. Ask which maintenance checks are yours and which require an authorised technician. Keep the instructions, serial numbers and order details together. Find out who handles motor or control faults and how to request service. A long list of presets is less useful if a basic function is difficult to operate. Compare [bed heights](/beds/bed-height-getting-in-and-out), [mattress materials](/mattresses/mattress-types-overview) and [companies with adjustable ranges](/companies/?type=adjustable). ## Frequently asked questions ### Can any mattress go on an adjustable bed? No. Obtain confirmation that the exact mattress model is approved for the exact adjustable base. A foam, latex or pocket-sprung label alone does not establish compatibility with repeated bending. ### What does an adjustable bed’s weight limit include? The definition varies. Ask whether it is a user-weight limit or includes the mattress and bedding, whether it applies per side, and whether it applies while moving. Use the written model instructions. ### Can a couple adjust each side separately? Only a suitable dual system allows independent movement. It needs the approved mattress arrangement, commonly two separate mattresses. Do not assume an ordinary zipped pair can stay joined while one side moves. ### What is a zero-gravity bed position? This is a name used for a preset with the head and legs raised. Angles and controls differ by model. It is a comfort setting and does not establish a medical benefit. --- Source: https://bedguide.co.uk/beds/adjustable-beds/ · BedGuide — educational encyclopedia, no affiliate commission.
