An ottoman bed is one of the best ways to claw back storage in a bedroom, but the moment you start shopping you hit a wall of terms. Gas-lift, side-lift, side-opening, end-lift, electric. They sound like they might all mean different things, and it is not obvious which one suits your room. Get it wrong and you end up with a bed you cannot open properly because a wardrobe is in the way.
This guide sorts out what each term actually means, how the mechanisms work, and how to choose between a side-lift ottoman bed and an end-opening one based on the room you have. By the end you will know exactly which to order.
First, what an ottoman bed actually does
An ottoman bed is a divan base where the whole mattress platform lifts up on a hinged, assisted mechanism to reveal a deep storage cavity underneath. Unlike a drawer divan, which gives you two or four boxes in the sides, an ottoman opens up the entire footprint of the bed as one large space. That is enough room for spare duvets, seasonal clothing, luggage and the sort of bulky items that never fit anywhere else.
The base does the heavy work for you. Lift the mattress a little and the mechanism takes over, holding it open safely while you load or unload. Lower it and it settles back down under control. The two things that vary between ottoman beds are the lifting system that provides that assistance and the direction the bed opens in.
The gas-lift mechanism, and why it matters
Gas-lift is the system that makes the whole thing possible. Built into the base are gas-piston struts, the same kind of pressurised strut you find holding up a car boot. They carry most of the weight of the mattress and platform, so you lift with very little effort and the bed stays open without you having to prop it.
Quality matters here more than anywhere else on the bed. Cheap struts weaken over time, so the mattress starts to feel heavy and the platform no longer holds its position. Our ottoman bases use robust gas-lift struts rated for years of daily use, and because our beds are medi-endorsed, the mechanism is built to open smoothly without the awkward straining that can bother anyone with a bad back. When people talk about a gas-lift ottoman, they are describing this lifting system. Side-lift, side-opening and end-lift then describe the direction that system opens in.
Side-lift and side-opening ottoman beds
A side-lift ottoman bed, also called a side-opening ottoman, hinges along one long side of the bed. The mattress and platform rise up sideways, so you access the storage from the side of the bed rather than the foot.
The big advantage is length clearance. Because the bed opens sideways, you do not need any spare space at the foot end, which makes a side-lift ottoman bed a strong choice when the foot of your bed sits close to a wall, a radiator or a chest of drawers. What you do need is room along one side to stand while the platform is raised. Side opening also tends to suit smaller and single sizes particularly well, where a sideways lift is light and easy to manage on your own.
One practical tip. A side-opening ottoman usually opens from a fixed side, left or right, so think about which side of your bed has the clear floor space before you order. Pushing one side against a wall and then choosing that same side to open from is the most common mistake people make.
End-lift ottoman beds
An end-lift ottoman, sometimes called foot-opening, hinges at the foot of the bed. The mattress rises from the bottom end and you access the storage by standing at the foot of the bed.
This style is often the easier lift on larger beds. The hinge geometry on a double, king or super king means the weight balances well, so an end-lift feels stable and controlled even on a big mattress. The trade-off is space. You need clear floor at the foot of the bed to stand and to let the platform swing up, so end-lift suits rooms where the bed sits with open space in front of it rather than tucked into a corner.
Electric end-lift ottoman beds
If you want the storage without doing any of the lifting yourself, an electric ottoman is the one to look at. Our Electric End Lift Ottoman Divan Bed Base swaps the gas struts for powerful electric actuators built into each side of the base, so the whole mattress platform rises and lowers at the touch of a button. A wireless remote does the work, the motor is quiet, and the movement stays smooth and controlled from start to finish.
That makes it a real help for anyone who finds a manual lift awkward, and it handles a heavy mattress with ease, taking up to 75kg on the lift itself. The storage is the headline though. With a 25cm deep cavity across the whole base, it holds around four times as much as a standard divan with drawers, which turns the space under your bed into proper storage for a whole room's worth of things. It is built to last too, with a reinforced top, solid sides, strong corner joints and a rubberised anti-slip finish that keeps your mattress from shifting. Made to order in Britain, it arrives as two preassembled pieces that link together, so setup is quick. It does need a mains power connection, and the cable is included.

How to choose the right opening for your room
The mechanism you want comes down to the shape of your room and where the bed sits in it, not personal taste alone.
If your bed backs into a corner or the foot is close to a wall or furniture, a side-lift ottoman bed is usually the answer, as long as you have standing room down one side. If your bed sits out in the room with clear floor at the foot, an end-lift works well and is often the smoother lift on a king or super king. For single and small double rooms where space is tight all round, side opening tends to be the most flexible. Measure the clear floor space on each side and at the foot before you decide, and always allow enough height for the mattress to rise fully, especially under a sloped or low ceiling.
Whichever direction you choose, the storage capacity underneath is broadly the same, since the cavity fills the footprint of the bed either way. The opening direction is about access, not how much you can fit.
Storage without giving up support
A common worry is that all this clever engineering means a weaker base or a bed that sags. It should not. A well-built ottoman keeps the same solid, even platform that makes a divan good for your back in the first place, so your mattress is supported properly across its whole surface. The lifting mechanism sits within that structure rather than replacing it. That is why our ottoman range pairs naturally with orthopaedic and pocket spring mattresses, giving you deep storage and proper support in one bed.
You can finish the base in a fabric that suits your room too, from the linen-like Lino to soft Plush Velvet or warm Wool, so the storage stays completely hidden and the bed looks like any other handsome divan.
Ready to reclaim the space under your bed
Once you know your room, choosing an ottoman is simple. Match the opening direction to your clear floor space, pick a base with a proper gas-lift mechanism, and you have storage for a whole room's worth of clutter without adding a single piece of furniture.
